In addition, research data have shown that young collared pikas rarely disperse over 300 m away from their original den, and adults hardly ever leave an established territory. Closely related to hares and rabbits, pikas are charismatic but lesser known members of the order Lagomorpha. [15] The males receive the females around the end of spring. 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. Habitat and biology. Learn about Yukon Collared Pika and how and where to view them. [3] This species is known as an ecotone species for the way that it keeps its shelter and food storage separate from each other. Because of this, they actually needcold temperatures, and can die if exposed to hotter climates. [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. They live in mountainous terrain with large boulders and talus slopes, which often have rock slides. [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. Your adoption kit comes with a plush toy, a stunning poster with species facts, a personalized certificate and an optional reusable tote bag! 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. [9] Their winter pelts are similar to O. princeps, but during the other seasons, O. collaris' fur is a darker gray and is less thick than in the winter;[8] consequently, they only have one annual molt. [10] During the summer, young that resemble the size of an adult are fully gray, while actual adults have brown stains around their heads or necks. [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. 1987. [8] In 1973, during the isolation of the Wisconsin glaciation, O. collaris may have become its own species separate from O. Population densities are generally higher on south-facing slopes presumably because of their higher primary productivity. Collared pikas are diurnal and they do not hibernate in winter. Its sharp, curved claws help it climb easily from rock to rock. [3] Therefore, the collared pika is seen as an asocial species and prefers solitude. 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. Tiere Collared Pika oder Arctic Ground Squirrel? 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. Given their susceptibility to climate change, Collared Pika is listed as Special Concern in … The collared pika (Ochotona collaris) is the only species of pika found in Alaska. [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. A Collared pika is a generalist herbivore (folivore), eating the leaves and stems of various grasses, small shrubs and forbs. [Updated by COSEWIC- Nov. 2011] Top Collared pikas sit to call with their body hunched up and their nose pointed slightly into the air. Collared Pikas inhabit primarily alpine boulder fields (talus) that are interspersed with meadow. [3] This gap encompasses both British Columbia and Alberta, Canada. Females are responsible for the majority of parental care. [7] Thousands of trips are made during July and August to collect vegetation for winter. [9] They are most active during the morning and late afternoon. They live in mountainous terrain with large boulders and talus slopes, which often have rock slides. [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. [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?] your own Pins on Pinterest Outside Canada, Collared Pikas occur in southern and central Alaska. Pick one: Collared Pika. "Ochotona collaris" (On-line), Animal Diversity Web. Much of the day they spend grazing or gathering vegetation to store for winter, a foraging behavior called "haying." “Forage selection by collared pikas, Ochotona collaris, under varying degrees of predation risk.”, Kays, Roland W., Wilson, Don E.. “ 2009. [8] Parturition timing for northern alpine herbivores is vital due to the brief snow-free timeframe and lack of food sources. [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. [9] Collared Pikas are behaviorally restricted to talus patches … These animals are kleptoparasitic and steal food from one another. Their hay piles could provide food for other herbivorous mammals. [13] Gathering begins to take place around the end of June or beginning of July and increases at a constant rate as time progresses. Those species that burrow live in less mountainous regions known as steppe, or grassland. Collared Pikas mostly live in cool and dry mountain boulder fields, or talus, with nearby meadows. "Coney" is a generic word for many small mammals that live amongst rocks, including pika and hyrax. [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. Litters are typically of two or three offspring, though there have been reports of litters with up to six offspring. 2. [8] They have five digits on each front foot and only four on each hind foot. [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. [14] The young remain in the nest around 30 days before they are weaned and emerge to the surface. Due to these talus sites, the species’ range distribution is broken up into several condensed areas. Aug 9, 2013 - This Pin was discovered by Betty Hatcher Moore. They consume their soft fecal pellets to reduce the loss of nutritional value in their food. According to IUCN, the Collared pika is common and widespread throughout its range but no overall population estimate is available. Most species live on rocky mountainsides, where numerous crevices are available for their shelter, although some pikas also construct crude burrows. [8] While some mammals have reduced clavicles for more range of motion, the collared pika has a well-developed clavicle supporting the scapula. The breeding season peaks from May to early June. 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. 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. Collared pika (O. collaris) is found in northern BC and throughout YT and Alaska. A pika's call is unmistakable once you have heard it: a single, piercing note like “ank” or “ink” heard over several hundred yards. 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 … 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… [17] As a collared pika prepares to call, it sits with a hunched back and points its nose upward. vs: Arctic Ground eichhörnchen zanhar1 posted vor 10 Monaten: view results | next poll >> Tiere More Polls. The Liard River valley may form a barrier between the Collared Pika and the more southern American Pika. Let's move on to another Pika that might be going through some changes. [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. Young remain in their nest for about 30 days before being weaned, when they emerge to the surface. Collared Pikas inhabit primarily alpine boulder fields (talus) that are interspersed with meadow. “We lure them into live traps with native vegetation,” Christie said. [10] The food caches have been seen to be similar to the size of location of storage. [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. But don't be fooled — these mammals are known for their alarm-like call and being territorial. Pikas are highly alert, and have excellent hearing and vision. [2] Due to these talus sites, the species’ range distribution is broken into several condensed areas. They typically produce one litter per year, but may produce two litters without successful weaning. (Pg. 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. This talus-meadow combination offers access to forage (meadow) and shelter from predators and weather (talus). [8] This territorial call informs neighboring collared pikas of haypile possession. 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. They prefer living along the borders of talus slopes that have meadows and patches of high-quality vegetation in the immediate vicinity. [12], Collared pikas are diurnal herbivores and spend time foraging through vegetation during the summer. [9], The female’s gestation period lasts about 30 days and produces a litter of blind and almost hairless offspring. 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. Collared Pika on The IUCN Red List site -, https://en.wikipedia.org/wiki/Collared_pika, http://www.iucnredlist.org/details/41257/0. 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. [9] Sexual dimorphism makes perceiving how much the male invests in nurturing the young difficult. 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. more polls >> Use Classi that allow for the hunting of collared pikas. [8] They do not have a pubic symphysis therefore it does not have a pubic arch within its pelvic girdle. They are mainly solitary, but are sometimes seen in pairs. They are sexually mature where they are one year old. 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. These animals vocalize often during hay gathering. [9] The female is the one that yields the most parental investment and is burdened by energetic constraints during gestation and lactation. Range map information. pika habitat. All but two of the 30 living species of pika occur in Asia, where they … “COLLARED PIKA (OCHOTONA COLLARIS) OCCUPANCY IN TOMBSTONE TERRITORIAL PARK, YUKON.”, Morrison, Shawn, Barton, Luc, Caputra, Peter, Hik, David S.. 2004. [8] They range between 130 and 200 g in body mass and 17.8 to 19.8 cm in length. 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 pika on Hatcher Pass, Alaska Pikas are native to cold climates, mostly in Asia , North America , and parts of Eastern Europe . It is the only pika found in Alaska. [2] In various regions of the Yukon, the range is around one to four pikas per hectare. [9] They spend no time burrowing because they use their talus sites for protection and habitation. [16], Collared pikas are a fairly vocal species. collared pika calls transmit with less degradation across their own species’ habitat than the habitat of their congener. They sometimes eat birds, which provide them with protein and fat. Collared pikas are easily found because you can hear their alarm call when you walk past them. 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. The boulders help shelter the pikas from weather and predators. 2015), but expectations of future distributional change are equivocal (COSEWIC 2011; Hope et al. All except two of the 30 species of pika alive today occur in Asia, which is probably where they originated. Collared Pikas are behaviorally restricted to talus patches and typically remain within 10 metres of the talus edge when foraging in meadows. [11] Although both can reproduce at one year of age, the male’s reproductive success is reliant on acquiring habitat and drawing females. Response Statement - Collared Pika. 30 days is the period of gestation. This talus-meadow combination offers access to forage (meadow) and shelter from predators and weather (talus). 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. With your symbolic adoption, you're helping WWF-Canada ensure the long-term survival of species like the collared pika and its habitat. [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. 2015; Leach et al. [8] Collared pikas tend to have multiple haystacks of vegetation throughout their home range and often dwell in the same site annually. Collared pikas also sometimes live in areas close to sea level in Alaska and British Columbia. [13] Collared pikas have also been found to be the victims of parasitism to fleas and parasitic helminthes such as Sarcocystis species, which have been found in their striated muscles. This dataset shows modelled habitat suitability for the Collared Pika (Ochotona collaris) under current and projected future conditions. [11] They have constricted, flat skulls with no supraorbital processes, slender zygomatic arches, and 26 teeth. The Collared pika is a key species that is consumed by numerous predators (ermines, weasels, foxes, owls, eagles). [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. 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. [6] Some individuals have been observed collecting and consuming dead birds as sources of fat and protein. [8], The estimated population density is roughly around 6.4 to 7.2 individuals per hectare. Pikas defend individual territories of about 15 to 25 m radius. princeps. Collared Pikas live in mountainous areas and commonly inhabit boulder fields found above tree lines and adjacent to alpine meadows. [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. [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. The vast majority of species live in mountainous regions among the rocks and crevices. [8] Of the 30 existing species of pika, only two inhabit North America, O. collaris and O. princeps. "Pika" comes from the Siberian word for this animal, "puka." They rarely forage further than 10 m from the talus into meadows. Both the males and females of this species are very vocal. This helps the Pika stay warm in the freezing temperatures. [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. They prefer to live at the edges of talus slopes, where there are meadows and areas of high-quality vegetation immediately nearby. They will also eat low-lying vegetation such as lichen that is under the snow during the winter. Collared pikas are the only pika species found in Alaska. [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. Females produce up to two litters per year, of 2 to 6 young, born in nests within the talus. They can be easily found because of their alarm call that carries across the alpine when you walk by. How do you catch a pika? 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. Collared pikas live in mountainous terrain with talus slopes and large boulders, which often presents rock slides. As they look like small rabbits, naturalists at first called Collared pikas coneys or rock rabbits. 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. The skull of a collared pika is relatively flat, and it does not have a spongy auditory bullae or a supraorbital process. [2] Both collared pikas and American pikas are commonly believed to be philopatric species. 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. princeps. Collared pikas sure are cute, eh? habitat and physiological requirements (Morrison and Hik 2007; COSEWIC 2011). [9] The mortality rate is high during winter and they have suffered from a continuous reduction of population over time. [2] Due to collared pikas being a cold-adapted species, their resilience to climate change is limited, so they have a high risk of extirpation of any populations found at lower altitudes and lower in latitude. Which of these three animals do you like the most? 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. 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 Pika (Ochotona collaris) in typical rockslide habitat near Hatcher Pass in August on a sunny day. Collared Pikas, both male and female, may have multiple mates. 2. They do not burrow but instead take shelter within their talus habitats. 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. 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. There is one designatable unit for Collared Pika in Canada. [11] During their rest periods, collared pikas have been found to sit on rocks and expose themselves to the sunlight. [9] Adult males specifically have their own call that sounds like a strong series of “kie” calls and clicking during mating season. It is closely related to the American pika (O. princeps), but it is a monotypic form containing no recognized subspecies. 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. Mammals of North America: (Second Edition).” Princeton University Press. We found no support for the acoustic adaptation hypothesis. [12], The lifespan of O. collaris can be up to 7 years in the wild. Currently this species is classified as Least Concern (LC) on the IUCN Red List. 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. [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. Collared pika with identification tag. Juvenile pikas can achieve the size of an adult around 40 to 50 days. Collared pikas are asocial animals and constantly chase away intruders to defend their territory. Collared pikas impact grass and herbaceous plant species in their high elevation habitats. Collared pikas will at times also inhabit areas near sea level in British Columbia and Alaska. [14] However, the pinnacle of the mating season arises in May and early June. [2], MacDonald, Stephen O. and Jones, Clyde. They have stocky bodies, large round ears, short legs, and almost no tail. “They readily go into traps to grab the plant material and bring it back to their haypiles. These analyses were applied to data collected from a ten year study in the Ruby Ranges in the Yukon Territory. The appearance of collared pikas is similar to other members of the genus Ochotona. 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, 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). 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. [12] Consequently, collared pikas have been recognized as an indicator species for the effect of climate change on alpine ecosystems. Around 60% of collared pikas are found in regions of Canada, with most of them being in Yukon. Geographic call variation in these two species of pikas likely reflects genetic divergence, and may be a result of separate evolutionary histories. [17] When interacting on a territory, collared pikas use a softer call than their normal vocalizations. A pika has fur-covered feet, but its toe pads are bare. [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. Cute or not: desert golden mole? Accessed October 03, 2014 at, Kukka, Piia M., McCulley, Alice, Suitor, Mike, Eckert, Cameron D. and Jung, Thomas S.. 2014. Though there is a wide variety of species, all are adapted to life in cold climates. [9], Collared pikas are defenseless against predators and can only hide within cracks or crevices in the mountainous areas where they live; the rocks of the terrain are their only shelter. [2] Around 60% of collared pikas are found in regions of Canada, with most of them being in Yukon. [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. They are called "coneys," "rock rabbits," and "little chief hares" In North America. 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. This species tends to mate with the nearest neighbors, a system known as ‘facultatively (functionally) monogamous.’ In monogamous behavior, males mate only with one female. Adult size is reached after just 40 to 50 days. [10], O. collaris has been classified as of least concern for conservation status according to the IUCN Red List of Threatened Species,[2] yet as said by the Status of Endangered Wildlife in Canada, as a result of collared pikas inhabiting areas with fast climate changes and their sensitivity to climatic variation, they are considered of special concern. [13] When gathering food, pika rarely travels more than 10 m away from its talus site. Some species also construct burrows in the soil. Although heard, these animals are not necessarily so easy to see because they are camouflaged perfectly amongst the rocks. A Collared pika is born blind and almost hairless. Alaska. [8] Each individual within this species preserves its own territory and its own vegetation cache or haypile, and defends it with full force. [8] This species is often kleptoparasitic and takes food from others. A pika, archaically spelt pica, is a small-sized mountain-dwelling mammal native to Asia and North America. Habitat. 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. [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. Their hay piles could provide food for other herbivorous mammals. 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. Puma or Hyena? Black Bellied Hamster or Quokka? 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. The word pika is derived from the Siberian name for this animal, puka. They are lesser known but nonetheless charismatic members of the order Lagomorpha and are closely related to rabbits and hares. [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. 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.
