“Forage selection by collared pikas, Ochotona collaris, under varying degrees of predation risk.”, Kays, Roland W., Wilson, Don E.. “ 2009. princeps. Collared pikas live in central and southern Alaska and parts of Canada in boulder fields. [3] The distance in which the collared pika ventures out to forage is highly dependent on level of predation risk. They sometimes eat birds, which provide them with protein and fat. [7] Thousands of trips are made during July and August to collect vegetation for winter. [11] The parturition time of most collared pikas is often synchronous in terms of breeding,[11] however there has been a study that has identified some correlation between variation in initiating the first litter and the variation of timing of the snowmelt. [14], Collared pikas generally mate with their nearest neighbors and are believed to be facultatively monogamous, but they have also been predicted to participate in polygynandry and reproduce with multiple partners, because males often travel to territories of several females during the spring before mating season begins. Their hay piles could provide food for other herbivorous mammals. In North America, they also are called "rock rabbits," "coneys," and "little chief hares." Once close to its home territory, the Collared pika may approach within several meters, if you stay very quiet and still for a few minutes. Collared pikas are easily found because you can hear their alarm call when you walk past them. more polls >> Use Classi But don't be fooled — these mammals are known for their alarm-like call and being territorial. collared pika calls transmit with less degradation across their own species’ habitat than the habitat of their congener. 2. These animals are kleptoparasitic and steal food from one another. These animals vocalize often during hay gathering. O. collaris is distributed over a wide range of terrain that encompasses the west side of the Northwest Territories, almost all of the Yukon Territory, northern British Columbia, and the central and southern parts of Alaska. The breeding season peaks from May to early June. Collared Pikas are behaviorally restricted to talus patches and typically remain within 10 metres of the talus edge when foraging in meadows. They are known by various names including cony and rock rabbit, the latter referring to the fact that N American and some Asian pikas occur only in rocky habitats. They are called "coneys," "rock rabbits," and "little chief hares" In North America. pika habitat. [2] It is asocial, does not hibernate,[5] and spends a large part of its time in the summer collecting vegetation that is stored under rocks ("haypiles") as a supply of food for the winter. Outside Canada, Collared Pikas occur in southern and central Alaska. It is closely related to the American pika (O. princeps), but it is a monotypic form containing no recognized subspecies. Collared pikas are the only pika species found in Alaska. Pikas defend individual territories of about 15 to 25 m radius. All except two of the 30 species of pika alive today occur in Asia, which is probably where they originated. Collared pikas live in mountainous terrain with talus slopes and large boulders, which often presents rock slides. Both the males and females of this species are very vocal. [9], O. collaris is distributed over a wide range of terrain that encompasses the west side of the Northwest Territories, almost all of the Yukon Territory, northern British Columbia, and the central and southern parts of Alaska. “COLLARED PIKA (OCHOTONA COLLARIS) OCCUPANCY IN TOMBSTONE TERRITORIAL PARK, YUKON.”, Morrison, Shawn, Barton, Luc, Caputra, Peter, Hik, David S.. 2004. All but two of the 30 living species of pika occur in Asia, where they … [14] The young remain in the nest around 30 days before they are weaned and emerge to the surface. [14] However, the pinnacle of the mating season arises in May and early June. You need to focus on where the call is coming from and watch out for movement among rocks, or the pika's silhouette against the sky. These analyses were applied to data collected from a ten year study in the Ruby Ranges in the Yukon Territory. They will also eat low-lying vegetation such as lichen that is under the snow during the winter. [8] In 1973, during the isolation of the Wisconsin glaciation, O. collaris may have become its own species separate from O. Geographic call variation in these two species of pikas likely reflects genetic divergence, and may be a result of separate evolutionary histories. The Liard River valley may form a barrier between the Collared Pika and the more southern American Pika. They consume their soft fecal pellets to reduce the loss of nutritional value in their food. Collared Pika (Ochotona collaris) in typical rockslide habitat near Hatcher Pass in August on a sunny day. [9] The female is the one that yields the most parental investment and is burdened by energetic constraints during gestation and lactation. [9], The female’s gestation period lasts about 30 days and produces a litter of blind and almost hairless offspring. Tiere Collared Pika oder Arctic Ground Squirrel? Litters are typically of two or three offspring, though there have been reports of litters with up to six offspring. Juvenile pikas can achieve the size of an adult around 40 to 50 days. They live in mountainous terrain with large boulders and talus slopes, which often have rock slides. [3] Therefore, the collared pika is seen as an asocial species and prefers solitude. Because of this, they actually needcold temperatures, and can die if exposed to hotter climates. [2] Nevertheless, the collared pika may be susceptible to the negative effects of climate change, and some investigation should be instigated to monitor the negative effects of the new unlimited, year-round hunting rules[where?] [9] Sexual dimorphism makes perceiving how much the male invests in nurturing the young difficult. In relation to the location of distribution of the American pika, O. collaris is located farther north of those regions and is separated by 800 km. [8] The studies of the size variation of the fossils showed that the morphology of Pleistocene pikas was flexible with the alteration of environments from early to middle Pleistocene in both Alaska and Yukon. [17] When interacting on a territory, collared pikas use a softer call than their normal vocalizations. Collared pika with identification tag. The collared pika (Ochotona collaris) is a species of mammal in the pika family, Ochotonidae, and part of the order Lagomorpha which comprises rabbits, hares, and pikas. According to IUCN, the Collared pika is common and widespread throughout its range but no overall population estimate is available. [2], MacDonald, Stephen O. and Jones, Clyde. Collared Pika on The IUCN Red List site -, https://en.wikipedia.org/wiki/Collared_pika, http://www.iucnredlist.org/details/41257/0. [9] Adult males specifically have their own call that sounds like a strong series of “kie” calls and clicking during mating season. Pikas are highly alert, and have excellent hearing and vision. [3] This species is known as an ecotone species for the way that it keeps its shelter and food storage separate from each other. Range map information. [8] This process of gathering and foraging for vegetation to add to their caches is referred to as “haying”, which is what they spend most of the day doing. Puma or Hyena? The collared pika (Ochotona collaris) is a species of mammal in the pika family, Ochotonidae, and part of the order Lagomorpha, which comprises rabbits, hares, and pikas. A pika has fur-covered feet, but its toe pads are bare. Cute or not: desert golden mole? The word pika is derived from the Siberian name for this animal, puka. [11] During their rest periods, collared pikas have been found to sit on rocks and expose themselves to the sunlight. This talus-meadow combination offers access to forage (meadow) and shelter from predators and weather (talus). habitat and physiological requirements (Morrison and Hik 2007; COSEWIC 2011). [Updated by COSEWIC- Nov. 2011] Top your own Pins on Pinterest Collared pikas will at times also inhabit areas near sea level in British Columbia and Alaska. [12], The lifespan of O. collaris can be up to 7 years in the wild. 36), Smithsonian National Museum of Natural History, http://animaldiversity.ummz.umich.edu/accounts/Ochotona_collaris/, "Notes on the Collared Pika, Ochotona collaris (Nelson), in Alaska", "Interannual Variation in Timing of Parturition and Growth of Collared Pikas (Ochotona collaris) in the Southwest Yukon", http://www.env.gov.yk.ca/publications-maps/documents/PikaSurveyReport2013.pdf, http://www.nrcresearchpress.com/doi/abs/10.1139/z04-024#.VDKy1SldX1s, https://books.google.com/books?id=YjIIRZwbWIEC&printsec=copyright&source=gbs_pub_info_r#v=onepage&q&f=false, https://en.wikipedia.org/w/index.php?title=Collared_pika&oldid=984533169, Vague or ambiguous geographic scope from June 2020, Creative Commons Attribution-ShareAlike License, This page was last edited on 20 October 2020, at 16:03. [2] Both collared pikas and American pikas are commonly believed to be philopatric species. princeps. They live in mountainous terrain with large boulders and talus slopes, which often have rock slides. It is a small (~160 gram) alpine lagomorph that lives in boulder fields of central and southern Alaska (U.S. ), and in parts of Canada, including northern British Columbia, Yukon, and western parts of the Northwest Territories. They do not burrow but instead take shelter within their talus habitats. [8] Parturition timing for northern alpine herbivores is vital due to the brief snow-free timeframe and lack of food sources. [9] However, although it has multiple haystacks, it mainly focuses on one while the others are much smaller and localized caches. During the cold winters, the collared pika does not hibernate, but instead stays active, counting on its food sources for energy and survival, and uses the snowpack as a means of insulation. [10] The food caches have been seen to be similar to the size of location of storage. They rarely forage further than 10 m from the talus into meadows. Their hay piles could provide food for other herbivorous mammals. Alaska. [8] Of the 30 existing species of pika, only two inhabit North America, O. collaris and O. princeps. A pika's call is unmistakable once you have heard it: a single, piercing note like “ank” or “ink” heard over several hundred yards. [8] Each individual within this species preserves its own territory and its own vegetation cache or haypile, and defends it with full force. Collared pikas live in central and southern Alaska and parts of Canada, including in the west in the Northwest Territories and in northern British Columbia, Yukon. It is the only pika found in Alaska. Col­lared pikas, Ochotona col­laris, are found in the moun­tain­ous re­gions of cen­tral and south­east­ern Alaska, in the Yukon-Tanana up­lands to the Chig­mit Moun­tains, and from the Richard­son Moun­tains north of the Artic cir­cle in the Yukon, west of the Macken­zie River in the North­west Ter­ri­to­ries, and south into north­west­ern British Co­lum­bia (Mac­Don­ald and Jones, 1987). [16], Collared pikas are a fairly vocal species. 2: Fur color: So in the picture to the right you see the Pika that hasn't had any change of fur color is having some problems: He grew his fur out but it grew out in the wrong color. 2. Closely related to hares and rabbits, pikas are charismatic but lesser known members of the order Lagomorpha. Juveniles remain on the natal territory for only a short time (a few days) before they become independent and disperse to find their own territories. [13] Gathering begins to take place around the end of June or beginning of July and increases at a constant rate as time progresses. [8] As observed, collared pikas are likely to use whatever is near the rockslides, such as leaves, flowering plants, berries, or anything else they can find to add to their food caches; even feces of other animals have been found within the haystacks of collared pikas. [12] Consequently, collared pikas have been recognized as an indicator species for the effect of climate change on alpine ecosystems. They are sexually mature where they are one year old. [8], Collared pika colonies are mainly found in the mountain regions and they typically inhabit rock slides near areas of vegetation and fields of meadows. Collared pikas sit to call with their body hunched up and their nose pointed slightly into the air. Other habitat quality features such as aspect, amount of meadow, and average survival (a proxy measure of patch quality) were also found to influence pika persistence. [8] Not much is known about the vocalization of collared pikas, but many studies on the American pika indicate a function of both a defensive mechanism and a warning signal against predators. More specifically, in Alaska, they occur most frequently in ranges around the Yukon-Tanana uplands and Chigmit Mountains, to the head of Lynn Canal near Skagway; in Canada, they occur from Rich… Due to these talus sites, the species’ range distribution is broken up into several condensed areas. Collared pika on Hatcher Pass, Alaska Pikas are native to cold climates, mostly in Asia , North America , and parts of Eastern Europe . [8] While some mammals have reduced clavicles for more range of motion, the collared pika has a well-developed clavicle supporting the scapula. Females produce up to two litters per year, of 2 to 6 young, born in nests within the talus. Population densities are generally higher on south-facing slopes presumably because of their higher primary productivity. Let's move on to another Pika that might be going through some changes. They can be easily found because of their alarm call that carries across the alpine when you walk by. They are lesser known but nonetheless charismatic members of the order Lagomorpha and are closely related to rabbits and hares. In addition, an interesting characteristic about the male collared pika is that it has no scrotum and the location of its testes is not visibly apparent. It is part of a dataset of projected current and future potential distributions of 366 terrestrial vertebrate species, including 12 amphibians, 237 birds, and 117 mammals, based on correlative bioclimatic models and projected changes in biomes. What kind of habitat/landscape has you favorite animals? [3] Collared pikas, like most other pikas, choose to live around rock slides to use the rocks as protection against the high temperatures they must endure throughout the day; they are referred to as cold-adapted lagomorphs. Collared pika (O. collaris) is found in northern BC and throughout YT and Alaska. Collared pikas are diurnal and they do not hibernate in winter. Response Statement - Collared Pika. An individual may build several haystacks within its home range and tends to each year inhabit the same location, usually under overhanging rocks, along boulders and in crevices. [16] Upon finding some asynchronous breeding among pikas, due to not being able to predict snowmelt, this type of breeding could ensure some success in breeding. [9] One of the main predators of the collared pika found in south-central Alaska is the ermine,[10] but also include martens, weasels, foxes, eagles, coyotes, and other various birds. Learn about Yukon Collared Pika and how and where to view them. [9] The soles of their feet are covered with long fur, while still exposing their digital pads on the soles of their feet and their curved claws. The boulders help shelter the pikas from weather and predators. Though there is a wide variety of species, all are adapted to life in cold climates. A Collared pika is born blind and almost hairless. [8] Collared pikas, both male and female, are reproductively developed at one year of age and give birth to two or three young each year in their nests within the talus. [8], In central Alaska, within the Pleistocene deposits, preserved specimens of collared pika were found along with some dung pellets; in addition to central Alaska, the Yukon territory also contained some fossilized specimens. Most species live on rocky mountainsides, where numerous crevices are available for their shelter, although some pikas also construct crude burrows. Which of these three animals do you like the most? Collared pikas sure are cute, eh? Mammals of North America: (Second Edition).” Princeton University Press. The Collared pika is a key species that is consumed by numerous predators (ermines, weasels, foxes, owls, eagles). [2] Due to these talus sites, the species’ range distribution is broken into several condensed areas. Aug 9, 2013 - This Pin was discovered by Betty Hatcher Moore. that allow for the hunting of collared pikas. “We lure them into live traps with native vegetation,” Christie said. vs: Arctic Ground eichhörnchen zanhar1 posted vor 10 Monaten: view results | next poll >> Tiere More Polls. Collared Pikas live in mountainous areas and commonly inhabit boulder fields found above tree lines and adjacent to alpine meadows. On the dorsal side of their bodies, they have dull grayish fur with gray patches on their shoulders and nape creating a distinguishable collar,[8] while on the ventral side they have an opaque white-colored fur. 2015; Leach et al. [11] They have constricted, flat skulls with no supraorbital processes, slender zygomatic arches, and 26 teeth. [9] 2015), but expectations of future distributional change are equivocal (COSEWIC 2011; Hope et al. Collared Pikas mostly live in cool and dry mountain boulder fields, or talus, with nearby meadows. The collared pika (O. collaris) of Alaska and northern Canada has been found on the isolated nunataks (crags or peaks surrounded by glaciers) in Kluane National Park, and O. macrotis has been recorded at 6,130 metres (20,113 feet) on the slopes of the Himalayas. They have stocky bodies, large round ears, short legs, and almost no tail. They typically produce one litter per year, but may produce two litters without successful weaning. As they look like small rabbits, naturalists at first called Collared pikas coneys or rock rabbits. [8] Collared pikas tend to have multiple haystacks of vegetation throughout their home range and often dwell in the same site annually. The Collared Pika (Ochotona collaris) is considered an indicator species for climate change, because of their sensitivity to climatic fluctuations and the natural isolation of suitable habitat. As pika distribution shifts northward in response to climate change, population growth at the leading edge of their range may be inhibited by a lack of available habitat. The pika has adapted to life in areas that rarely get above freezing and can overheat and die when exposed to temperatures as mild as 78 degrees Fahrenheit. Given their susceptibility to climate change, Collared Pika is listed as Special Concern in … [3] It is a small (about 160 g) alpine lagomorph that lives in boulder fields of central and southern Alaska (U.S.),[4] and in parts of Canada, including northern British Columbia, Yukon, and western parts of the Northwest Territories. Collared Pikas are behaviorally restricted to talus patches … They prefer living along the borders of talus slopes that have meadows and patches of high-quality vegetation in the immediate vicinity. Habitat and biology. Collared pikas are asocial animals and constantly chase away intruders to defend their territory. How do you catch a pika? Collared pika colonies are mainly found in the mountain regions and they typically inhabit rock slides near areas of vegetation and fields of meadows. [8] This territorial call informs neighboring collared pikas of haypile possession. Unlike other mountain species that can move to higher altitudes in warming climates, pikas live so high on the mountain that there is no where for them to go. [2] In various regions of the Yukon, the range is around one to four pikas per hectare. Young remain in their nest for about 30 days before being weaned, when they emerge to the surface. In this research project I applied multivariate analyses to explore the relationship between habitat occupancy by collared pikas and a number of spatial, environmental and climate variables. Collared Pikas inhabit primarily alpine boulder fields (talus) that are interspersed with meadow. Around 60% of collared pikas are found in regions of Canada, with most of them being in Yukon. More typically, however, they are found in the mountainous regions of central and southeastern Alaska, from the Richardson Mountains north of the Arctic circle in the Yukon, west of the … Similarly, habitat occupancy of collared pika was governed by talus patch size and connectivity (Franken and Hik 2004). [9] They are most active during the morning and late afternoon. Modeling of previous glacial periods suggest that the distribution of collared pika has decreased in response to warming after the Last Glacial Maximum (COSEWIC 2011; Hope et al. "Pika" comes from the Siberian word for this animal, "puka." Collared pikas impact grass and herbaceous plant species in their high elevation habitats. Pick one: Collared Pika. Black Bellied Hamster or Quokka? Females are responsible for the majority of parental care. [17] As a collared pika prepares to call, it sits with a hunched back and points its nose upward. “Forage selection by collared pikas, Ochotona collaris, under varying degrees of predation risk.”, Kays, Roland W., Wilson, Don E.. “ 2009. While there is no apparent concern for Collared pikas at this time, climate change could be a threat, as they are sensitive to high temperatures in their environment, and the high elevation habitats to which they are restricted are declining as a result of climate change. [8] Some features that are helpful in identifying O. collaris from O. princeps are the creamy-colored fur over the facial gland, which is brown in O. princeps; and in addition, the skull size of O. collaris is broader with a shorter nasal area, a greater tympanic bullae, and different teeth morphology than those of O. “They readily go into traps to grab the plant material and bring it back to their haypiles. [8] Collared pika calls sound like a recurring single sharp note with each series varying in loudness and is similar to the American pika’s short call. Adult size is reached after just 40 to 50 days. [12] Their homes have a range of about 30 m in diameter with caches and dens distancing from 30 to 70 m.[8] The way organisms respond to climate change can be a distinct and peculiar characteristic, so patterns between closely related species, such as the collared pika and the American pika, are important. A Collared pika is a generalist herbivore (folivore), eating the leaves and stems of various grasses, small shrubs and forbs. “Mammalian Species: Ochotona collaris.”, Leininger, C. 2009. The vast majority of species live in mountainous regions among the rocks and crevices. Good pika habitat consists of medium-sized boulders surrounded by alpine vegetation but not too overgrown with shrubs. [9] The mortality rate is high during winter and they have suffered from a continuous reduction of population over time. Much of the day they spend grazing or gathering vegetation to store for winter, a foraging behavior called "haying." We found no support for the acoustic adaptation hypothesis. [18] The struggle to survive the winters and the fast-rate climate variations have affected their growing season and availability of resources, especially from the negative impact of not having snowpacks to keep them insulated or to keep their food and shelters hidden from predators. [12], Collared pikas are diurnal herbivores and spend time foraging through vegetation during the summer. (Pg. Collared pikas live in central and southern Alaska and parts of Canada, including in the west in the Northwest Territories and in northern British Columbia, Yukon. [13] When gathering food, pika rarely travels more than 10 m away from its talus site. Collared Pikas inhabit primarily alpine boulder fields (talus) that are interspersed with meadow. Its sharp, curved claws help it climb easily from rock to rock. The skull of a collared pika is relatively flat, and it does not have a spongy auditory bullae or a supraorbital process. [12] Currently, no actions are being taken to preserve this species, and no threats have been acknowledged against this species. They are mainly solitary, but are sometimes seen in pairs. [8], They are petite in size with longer hind limbs than their fore limbs, with their hind limbs being about 2.9 to 3.1 cm. [17] Both males and females can emit vocalizations from some sort of fixed position within their home ranges, especially during the period of gathering. [9] For both male and females, the average weight is around 157 g, with maximum growth rates increasing moving toward the northern parts of collared pika territories.

collared pika habitat

[11] Although both can reproduce at one year of age, the male’s reproductive success is reliant on acquiring habitat and drawing females. Due to the remote nature of its range in Canada, direct disturbance to Collared Pika habitat and populations has been minimal and is expected to remain so in the coming decades. [6] Some individuals have been observed collecting and consuming dead birds as sources of fat and protein. The appearance of collared pikas is similar to other members of the genus Ochotona. [15] No population trend is known, but the population of collared pikas has experienced a decline since 1995 in the Yukon area, and is proposed to have a higher probability of extinction within that specific area in 10 to 15 years. There is one designatable unit for Collared Pika in Canada. This small rabbit-relative is a Beringian relict that is restricted to talus slopes in alpine areas in northern west British Columbia, Yukon, and Northwest Territories. The "collar" from which the Collared pika gets its name is a distinct grayish patch on its shoulder and neck, which is in definite contrast with the white fur on the chest and stomach. A pika, archaically spelt pica, is a small-sized mountain-dwelling mammal native to Asia and North America.
“Forage selection by collared pikas, Ochotona collaris, under varying degrees of predation risk.”, Kays, Roland W., Wilson, Don E.. “ 2009. princeps. Collared pikas live in central and southern Alaska and parts of Canada in boulder fields. [3] The distance in which the collared pika ventures out to forage is highly dependent on level of predation risk. They sometimes eat birds, which provide them with protein and fat. [7] Thousands of trips are made during July and August to collect vegetation for winter. [11] The parturition time of most collared pikas is often synchronous in terms of breeding,[11] however there has been a study that has identified some correlation between variation in initiating the first litter and the variation of timing of the snowmelt. [14], Collared pikas generally mate with their nearest neighbors and are believed to be facultatively monogamous, but they have also been predicted to participate in polygynandry and reproduce with multiple partners, because males often travel to territories of several females during the spring before mating season begins. Their hay piles could provide food for other herbivorous mammals. In North America, they also are called "rock rabbits," "coneys," and "little chief hares." Once close to its home territory, the Collared pika may approach within several meters, if you stay very quiet and still for a few minutes. Collared pikas are easily found because you can hear their alarm call when you walk past them. more polls >> Use Classi But don't be fooled — these mammals are known for their alarm-like call and being territorial. collared pika calls transmit with less degradation across their own species’ habitat than the habitat of their congener. 2. These animals are kleptoparasitic and steal food from one another. These animals vocalize often during hay gathering. O. collaris is distributed over a wide range of terrain that encompasses the west side of the Northwest Territories, almost all of the Yukon Territory, northern British Columbia, and the central and southern parts of Alaska. The breeding season peaks from May to early June. Collared Pikas are behaviorally restricted to talus patches and typically remain within 10 metres of the talus edge when foraging in meadows. They are known by various names including cony and rock rabbit, the latter referring to the fact that N American and some Asian pikas occur only in rocky habitats. They are called "coneys," "rock rabbits," and "little chief hares" In North America. pika habitat. [2] It is asocial, does not hibernate,[5] and spends a large part of its time in the summer collecting vegetation that is stored under rocks ("haypiles") as a supply of food for the winter. Outside Canada, Collared Pikas occur in southern and central Alaska. It is closely related to the American pika (O. princeps), but it is a monotypic form containing no recognized subspecies. Collared pikas are the only pika species found in Alaska. Pikas defend individual territories of about 15 to 25 m radius. All except two of the 30 species of pika alive today occur in Asia, which is probably where they originated. Collared pikas live in mountainous terrain with talus slopes and large boulders, which often presents rock slides. Both the males and females of this species are very vocal. [9], O. collaris is distributed over a wide range of terrain that encompasses the west side of the Northwest Territories, almost all of the Yukon Territory, northern British Columbia, and the central and southern parts of Alaska. “COLLARED PIKA (OCHOTONA COLLARIS) OCCUPANCY IN TOMBSTONE TERRITORIAL PARK, YUKON.”, Morrison, Shawn, Barton, Luc, Caputra, Peter, Hik, David S.. 2004. All but two of the 30 living species of pika occur in Asia, where they … [14] The young remain in the nest around 30 days before they are weaned and emerge to the surface. [14] However, the pinnacle of the mating season arises in May and early June. You need to focus on where the call is coming from and watch out for movement among rocks, or the pika's silhouette against the sky. These analyses were applied to data collected from a ten year study in the Ruby Ranges in the Yukon Territory. They will also eat low-lying vegetation such as lichen that is under the snow during the winter. [8] In 1973, during the isolation of the Wisconsin glaciation, O. collaris may have become its own species separate from O. Geographic call variation in these two species of pikas likely reflects genetic divergence, and may be a result of separate evolutionary histories. The Liard River valley may form a barrier between the Collared Pika and the more southern American Pika. They consume their soft fecal pellets to reduce the loss of nutritional value in their food. Collared Pika (Ochotona collaris) in typical rockslide habitat near Hatcher Pass in August on a sunny day. [9] The female is the one that yields the most parental investment and is burdened by energetic constraints during gestation and lactation. [9], The female’s gestation period lasts about 30 days and produces a litter of blind and almost hairless offspring. Tiere Collared Pika oder Arctic Ground Squirrel? Litters are typically of two or three offspring, though there have been reports of litters with up to six offspring. Juvenile pikas can achieve the size of an adult around 40 to 50 days. They live in mountainous terrain with large boulders and talus slopes, which often have rock slides. [3] Therefore, the collared pika is seen as an asocial species and prefers solitude. Because of this, they actually needcold temperatures, and can die if exposed to hotter climates. [2] Nevertheless, the collared pika may be susceptible to the negative effects of climate change, and some investigation should be instigated to monitor the negative effects of the new unlimited, year-round hunting rules[where?] [9] Sexual dimorphism makes perceiving how much the male invests in nurturing the young difficult. In relation to the location of distribution of the American pika, O. collaris is located farther north of those regions and is separated by 800 km. [8] The studies of the size variation of the fossils showed that the morphology of Pleistocene pikas was flexible with the alteration of environments from early to middle Pleistocene in both Alaska and Yukon. [17] When interacting on a territory, collared pikas use a softer call than their normal vocalizations. Collared pika with identification tag. The collared pika (Ochotona collaris) is a species of mammal in the pika family, Ochotonidae, and part of the order Lagomorpha which comprises rabbits, hares, and pikas. According to IUCN, the Collared pika is common and widespread throughout its range but no overall population estimate is available. [2], MacDonald, Stephen O. and Jones, Clyde. Collared Pika on The IUCN Red List site -, https://en.wikipedia.org/wiki/Collared_pika, http://www.iucnredlist.org/details/41257/0. [9] Adult males specifically have their own call that sounds like a strong series of “kie” calls and clicking during mating season. Pikas are highly alert, and have excellent hearing and vision. [3] This species is known as an ecotone species for the way that it keeps its shelter and food storage separate from each other. Range map information. [8] This process of gathering and foraging for vegetation to add to their caches is referred to as “haying”, which is what they spend most of the day doing. Puma or Hyena? The collared pika (Ochotona collaris) is a species of mammal in the pika family, Ochotonidae, and part of the order Lagomorpha, which comprises rabbits, hares, and pikas. A pika has fur-covered feet, but its toe pads are bare. Cute or not: desert golden mole? The word pika is derived from the Siberian name for this animal, puka. [11] During their rest periods, collared pikas have been found to sit on rocks and expose themselves to the sunlight. This talus-meadow combination offers access to forage (meadow) and shelter from predators and weather (talus). habitat and physiological requirements (Morrison and Hik 2007; COSEWIC 2011). [Updated by COSEWIC- Nov. 2011] Top your own Pins on Pinterest Collared pikas will at times also inhabit areas near sea level in British Columbia and Alaska. [12], The lifespan of O. collaris can be up to 7 years in the wild. 36), Smithsonian National Museum of Natural History, http://animaldiversity.ummz.umich.edu/accounts/Ochotona_collaris/, "Notes on the Collared Pika, Ochotona collaris (Nelson), in Alaska", "Interannual Variation in Timing of Parturition and Growth of Collared Pikas (Ochotona collaris) in the Southwest Yukon", http://www.env.gov.yk.ca/publications-maps/documents/PikaSurveyReport2013.pdf, http://www.nrcresearchpress.com/doi/abs/10.1139/z04-024#.VDKy1SldX1s, https://books.google.com/books?id=YjIIRZwbWIEC&printsec=copyright&source=gbs_pub_info_r#v=onepage&q&f=false, https://en.wikipedia.org/w/index.php?title=Collared_pika&oldid=984533169, Vague or ambiguous geographic scope from June 2020, Creative Commons Attribution-ShareAlike License, This page was last edited on 20 October 2020, at 16:03. [2] Both collared pikas and American pikas are commonly believed to be philopatric species. princeps. They live in mountainous terrain with large boulders and talus slopes, which often have rock slides. It is a small (~160 gram) alpine lagomorph that lives in boulder fields of central and southern Alaska (U.S. ), and in parts of Canada, including northern British Columbia, Yukon, and western parts of the Northwest Territories. They do not burrow but instead take shelter within their talus habitats. [8] Parturition timing for northern alpine herbivores is vital due to the brief snow-free timeframe and lack of food sources. [9] However, although it has multiple haystacks, it mainly focuses on one while the others are much smaller and localized caches. During the cold winters, the collared pika does not hibernate, but instead stays active, counting on its food sources for energy and survival, and uses the snowpack as a means of insulation. [10] The food caches have been seen to be similar to the size of location of storage. They rarely forage further than 10 m from the talus into meadows. Their hay piles could provide food for other herbivorous mammals. Alaska. [8] Of the 30 existing species of pika, only two inhabit North America, O. collaris and O. princeps. A pika's call is unmistakable once you have heard it: a single, piercing note like “ank” or “ink” heard over several hundred yards. [8] Each individual within this species preserves its own territory and its own vegetation cache or haypile, and defends it with full force. Collared pikas live in central and southern Alaska and parts of Canada, including in the west in the Northwest Territories and in northern British Columbia, Yukon. It is the only pika found in Alaska. Col­lared pikas, Ochotona col­laris, are found in the moun­tain­ous re­gions of cen­tral and south­east­ern Alaska, in the Yukon-Tanana up­lands to the Chig­mit Moun­tains, and from the Richard­son Moun­tains north of the Artic cir­cle in the Yukon, west of the Macken­zie River in the North­west Ter­ri­to­ries, and south into north­west­ern British Co­lum­bia (Mac­Don­ald and Jones, 1987). [16], Collared pikas are a fairly vocal species. 2: Fur color: So in the picture to the right you see the Pika that hasn't had any change of fur color is having some problems: He grew his fur out but it grew out in the wrong color. 2. Closely related to hares and rabbits, pikas are charismatic but lesser known members of the order Lagomorpha. Juveniles remain on the natal territory for only a short time (a few days) before they become independent and disperse to find their own territories. [13] Gathering begins to take place around the end of June or beginning of July and increases at a constant rate as time progresses. [8] As observed, collared pikas are likely to use whatever is near the rockslides, such as leaves, flowering plants, berries, or anything else they can find to add to their food caches; even feces of other animals have been found within the haystacks of collared pikas. [12] Consequently, collared pikas have been recognized as an indicator species for the effect of climate change on alpine ecosystems. They are sexually mature where they are one year old. [8], Collared pika colonies are mainly found in the mountain regions and they typically inhabit rock slides near areas of vegetation and fields of meadows. Collared pikas sit to call with their body hunched up and their nose pointed slightly into the air. Other habitat quality features such as aspect, amount of meadow, and average survival (a proxy measure of patch quality) were also found to influence pika persistence. [8] Not much is known about the vocalization of collared pikas, but many studies on the American pika indicate a function of both a defensive mechanism and a warning signal against predators. More specifically, in Alaska, they occur most frequently in ranges around the Yukon-Tanana uplands and Chigmit Mountains, to the head of Lynn Canal near Skagway; in Canada, they occur from Rich… Due to these talus sites, the species’ range distribution is broken up into several condensed areas. Collared pika on Hatcher Pass, Alaska Pikas are native to cold climates, mostly in Asia , North America , and parts of Eastern Europe . [8] While some mammals have reduced clavicles for more range of motion, the collared pika has a well-developed clavicle supporting the scapula. Females produce up to two litters per year, of 2 to 6 young, born in nests within the talus. Population densities are generally higher on south-facing slopes presumably because of their higher primary productivity. Let's move on to another Pika that might be going through some changes. They can be easily found because of their alarm call that carries across the alpine when you walk by. They are lesser known but nonetheless charismatic members of the order Lagomorpha and are closely related to rabbits and hares. In addition, an interesting characteristic about the male collared pika is that it has no scrotum and the location of its testes is not visibly apparent. It is part of a dataset of projected current and future potential distributions of 366 terrestrial vertebrate species, including 12 amphibians, 237 birds, and 117 mammals, based on correlative bioclimatic models and projected changes in biomes. What kind of habitat/landscape has you favorite animals? [3] Collared pikas, like most other pikas, choose to live around rock slides to use the rocks as protection against the high temperatures they must endure throughout the day; they are referred to as cold-adapted lagomorphs. Collared pika (O. collaris) is found in northern BC and throughout YT and Alaska. Collared pikas are diurnal and they do not hibernate in winter. Response Statement - Collared Pika. An individual may build several haystacks within its home range and tends to each year inhabit the same location, usually under overhanging rocks, along boulders and in crevices. [16] Upon finding some asynchronous breeding among pikas, due to not being able to predict snowmelt, this type of breeding could ensure some success in breeding. [9] One of the main predators of the collared pika found in south-central Alaska is the ermine,[10] but also include martens, weasels, foxes, eagles, coyotes, and other various birds. Learn about Yukon Collared Pika and how and where to view them. [9] The soles of their feet are covered with long fur, while still exposing their digital pads on the soles of their feet and their curved claws. The boulders help shelter the pikas from weather and predators. Though there is a wide variety of species, all are adapted to life in cold climates. A Collared pika is born blind and almost hairless. [8] Collared pikas, both male and female, are reproductively developed at one year of age and give birth to two or three young each year in their nests within the talus. [8], In central Alaska, within the Pleistocene deposits, preserved specimens of collared pika were found along with some dung pellets; in addition to central Alaska, the Yukon territory also contained some fossilized specimens. Most species live on rocky mountainsides, where numerous crevices are available for their shelter, although some pikas also construct crude burrows. Which of these three animals do you like the most? Collared pikas sure are cute, eh? Mammals of North America: (Second Edition).” Princeton University Press. The Collared pika is a key species that is consumed by numerous predators (ermines, weasels, foxes, owls, eagles). [2] Due to these talus sites, the species’ range distribution is broken into several condensed areas. Aug 9, 2013 - This Pin was discovered by Betty Hatcher Moore. that allow for the hunting of collared pikas. “We lure them into live traps with native vegetation,” Christie said. vs: Arctic Ground eichhörnchen zanhar1 posted vor 10 Monaten: view results | next poll >> Tiere More Polls. Collared Pikas live in mountainous areas and commonly inhabit boulder fields found above tree lines and adjacent to alpine meadows. On the dorsal side of their bodies, they have dull grayish fur with gray patches on their shoulders and nape creating a distinguishable collar,[8] while on the ventral side they have an opaque white-colored fur. 2015; Leach et al. [11] They have constricted, flat skulls with no supraorbital processes, slender zygomatic arches, and 26 teeth. [9] 2015), but expectations of future distributional change are equivocal (COSEWIC 2011; Hope et al. Collared Pikas mostly live in cool and dry mountain boulder fields, or talus, with nearby meadows. The collared pika (O. collaris) of Alaska and northern Canada has been found on the isolated nunataks (crags or peaks surrounded by glaciers) in Kluane National Park, and O. macrotis has been recorded at 6,130 metres (20,113 feet) on the slopes of the Himalayas. They have stocky bodies, large round ears, short legs, and almost no tail. They typically produce one litter per year, but may produce two litters without successful weaning. As they look like small rabbits, naturalists at first called Collared pikas coneys or rock rabbits. [8] Collared pikas tend to have multiple haystacks of vegetation throughout their home range and often dwell in the same site annually. The Collared Pika (Ochotona collaris) is considered an indicator species for climate change, because of their sensitivity to climatic fluctuations and the natural isolation of suitable habitat. As pika distribution shifts northward in response to climate change, population growth at the leading edge of their range may be inhibited by a lack of available habitat. The pika has adapted to life in areas that rarely get above freezing and can overheat and die when exposed to temperatures as mild as 78 degrees Fahrenheit. Given their susceptibility to climate change, Collared Pika is listed as Special Concern in … [3] It is a small (about 160 g) alpine lagomorph that lives in boulder fields of central and southern Alaska (U.S.),[4] and in parts of Canada, including northern British Columbia, Yukon, and western parts of the Northwest Territories. Collared Pikas are behaviorally restricted to talus patches … They prefer living along the borders of talus slopes that have meadows and patches of high-quality vegetation in the immediate vicinity. Habitat and biology. Collared pikas are asocial animals and constantly chase away intruders to defend their territory. How do you catch a pika? Collared pika colonies are mainly found in the mountain regions and they typically inhabit rock slides near areas of vegetation and fields of meadows. [8] This territorial call informs neighboring collared pikas of haypile possession. Unlike other mountain species that can move to higher altitudes in warming climates, pikas live so high on the mountain that there is no where for them to go. [2] In various regions of the Yukon, the range is around one to four pikas per hectare. Young remain in their nest for about 30 days before being weaned, when they emerge to the surface. In this research project I applied multivariate analyses to explore the relationship between habitat occupancy by collared pikas and a number of spatial, environmental and climate variables. Collared Pikas inhabit primarily alpine boulder fields (talus) that are interspersed with meadow. Around 60% of collared pikas are found in regions of Canada, with most of them being in Yukon. More typically, however, they are found in the mountainous regions of central and southeastern Alaska, from the Richardson Mountains north of the Arctic circle in the Yukon, west of the … Similarly, habitat occupancy of collared pika was governed by talus patch size and connectivity (Franken and Hik 2004). [9] They are most active during the morning and late afternoon. Modeling of previous glacial periods suggest that the distribution of collared pika has decreased in response to warming after the Last Glacial Maximum (COSEWIC 2011; Hope et al. "Pika" comes from the Siberian word for this animal, "puka." Collared pikas impact grass and herbaceous plant species in their high elevation habitats. Pick one: Collared Pika. Black Bellied Hamster or Quokka? Females are responsible for the majority of parental care. [17] As a collared pika prepares to call, it sits with a hunched back and points its nose upward. “Forage selection by collared pikas, Ochotona collaris, under varying degrees of predation risk.”, Kays, Roland W., Wilson, Don E.. “ 2009. While there is no apparent concern for Collared pikas at this time, climate change could be a threat, as they are sensitive to high temperatures in their environment, and the high elevation habitats to which they are restricted are declining as a result of climate change. [8] Some features that are helpful in identifying O. collaris from O. princeps are the creamy-colored fur over the facial gland, which is brown in O. princeps; and in addition, the skull size of O. collaris is broader with a shorter nasal area, a greater tympanic bullae, and different teeth morphology than those of O. “They readily go into traps to grab the plant material and bring it back to their haypiles. [8] Collared pika calls sound like a recurring single sharp note with each series varying in loudness and is similar to the American pika’s short call. Adult size is reached after just 40 to 50 days. [12] Their homes have a range of about 30 m in diameter with caches and dens distancing from 30 to 70 m.[8] The way organisms respond to climate change can be a distinct and peculiar characteristic, so patterns between closely related species, such as the collared pika and the American pika, are important. A Collared pika is a generalist herbivore (folivore), eating the leaves and stems of various grasses, small shrubs and forbs. “Mammalian Species: Ochotona collaris.”, Leininger, C. 2009. The vast majority of species live in mountainous regions among the rocks and crevices. Good pika habitat consists of medium-sized boulders surrounded by alpine vegetation but not too overgrown with shrubs. [9] The mortality rate is high during winter and they have suffered from a continuous reduction of population over time. Much of the day they spend grazing or gathering vegetation to store for winter, a foraging behavior called "haying." We found no support for the acoustic adaptation hypothesis. [18] The struggle to survive the winters and the fast-rate climate variations have affected their growing season and availability of resources, especially from the negative impact of not having snowpacks to keep them insulated or to keep their food and shelters hidden from predators. [12], Collared pikas are diurnal herbivores and spend time foraging through vegetation during the summer. (Pg. Collared pikas live in central and southern Alaska and parts of Canada, including in the west in the Northwest Territories and in northern British Columbia, Yukon. [13] When gathering food, pika rarely travels more than 10 m away from its talus site. Collared Pikas inhabit primarily alpine boulder fields (talus) that are interspersed with meadow. Its sharp, curved claws help it climb easily from rock to rock. The skull of a collared pika is relatively flat, and it does not have a spongy auditory bullae or a supraorbital process. [12] Currently, no actions are being taken to preserve this species, and no threats have been acknowledged against this species. They are mainly solitary, but are sometimes seen in pairs. [8], They are petite in size with longer hind limbs than their fore limbs, with their hind limbs being about 2.9 to 3.1 cm. [17] Both males and females can emit vocalizations from some sort of fixed position within their home ranges, especially during the period of gathering. [9] For both male and females, the average weight is around 157 g, with maximum growth rates increasing moving toward the northern parts of collared pika territories.
