Although they are primarily herbivorous, collared pikas have been recorded to consume birds as an opportunistic source of protein and fat (Krajick, 1998). Smith, A., N. Formozov, R. Hoffmann, Z. Changlin, M. Erbajeva. (Franken and Hik, 2004b; Morrison and Hik, 2007; Smith, 2008; Smith, et al., 2004), Collared pikas are one of several species of Ochotonidae that do not burrow; rather they take shelter in their talus habitats. Pp. States and southwestern Canada, and also the collared pika of northern Bc, the Yukon, western Northwest Territories, and Alaska. Distinctive skull characteristics of ochotonids are an absent supraobital process and spongy auditory bullae. They are known to spend much of their day grazing and collecting vegetation for their winter caches. Their hay piles could provide food for other herbivorous mammals. This material is based upon work supported by the breeding is confined to a particular season, reproduction that includes combining the genetic contribution of two individuals, a male and a female, places a food item in a special place to be eaten later. uses smells or other chemicals to communicate. A pika (/ ˈ p aɪ k ə / PY-kə; archaically spelled pica) is a small, mountain-dwelling mammal found in Asia and North America. Collared pikas are asocial animals and constantly chase away intruders to defend their territory. They are asocial and constantly defend their territory by chasing away intruders. Because they are highly sensitive to temperature changes and are restricted to talus outcrops, collared pika are likely to be threatened by climate change. Cached winter hay piles produced by other species of pikas are collected and harvested by farmers to feed domestic cattle and sheep in Siberia (Danell et al., 1998). Little is known about the vocalizations of collared pikas. Collare… Juveniles will disperse within the natal talus patch immediately following the end of gestation to make their own territory (Franken and Hik, 2004a). Pikas are only found in the western part of North America, from British Columbia, Canada to New Mexico, United States. In Canada, the Collared Pika occurs primarily in the mountainous regions of Yukon Territory, extending into northern British Columbia and into Northwest Territories west of the Mackenzie River. Juveniles emerge to t… Morrison, S., D. Hik. November 17, 2008 Nunataks. Note the short, round ears, and the light circle of fur around their neck that forms a “collar." Ecology, 88(11): 2752-2757. Also called "hoarding", defends an area within the home range, occupied by a single animals or group of animals of the same species and held through overt defense, display, or advertisement. Animal behavior, 44: 186-193. [17] Berlin Heidelberg: Springer-Verlag. 2004. 2004. A terrestrial biome with low, shrubby or mat-like vegetation found at extremely high latitudes or elevations, near the limit of plant growth. While this suggests there is no concern for populations at this time, they could respond negatively to climate change. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts. Mammalian herbivores in the boreal forests: their numerical fluctuations and use by man.. Conservation Ecology, 2(2): 9. 1990. The IUCN lists collared pikas as lower risk/least concern. This, in turn, alters growing season and food availability for collared pikas. This terrestrial biome includes summits of high mountains, either without vegetation or covered by low, tundra-like vegetation. Their skulls are relatively flat, with narrow zygomatic arches, short narrow rostra, and a fenestrated maxilla. Also, numerous birds of prey such as eagles and owls will hunt collared pikas (Broadbooks, 1965; Holmes, 1991; Morrison et al., 2004). Collared Pika Survival and Diet By Katie Christie The ecology and behavior of collared pikas is currently not well understood, but this species may be ... Defense instruction (DoDI) 4715.03 and Air Force Instruction (AFI) 32-7694. There are several known carnivorous predators, including ermine, foxes, weasels, lynx, and coyotes. With short limbs, very round body, an even coat of fur, and no external tail, they resemble their close relative, the rabbit, but with short, rounded ears. The differences in dispersal habits between American and collared pikas may be related to the lower densities that generally characterize the latter species. As a result, collared pika have been identified as a species of greatest conservation need for the Alaska Department of Fish and Game, and are of interest to federal land managers in Alaska, including project collaborators on military lands (Joint Base Elmendorf Richardson). Alpine or Altai Pika: O. alpina : China & areas of former USSR: Gray or Gansu Pika: O. cansus When calling, pikas sit with their body hunched and noses pointed slightly in the air. In fact, they are often found chasing away intruders. Females have up to two litters a year that range between 2 to 6 young each and average 2.2 individuals weaned. Tanya Dewey (editor), Animal Diversity Web. (MacDonald and Jones, 1987; Smith, 2008), Collared pika ventral fur is creamy white and the dorsal fur is grayish. Snow-pack is important in insulating pikas from temperature extremes during winter months. 1998. Smith, A. © 2020 Regents of the University of Michigan. In addition to their foraging activities, pikas also will engage in ‘kleptoparastism,’ stealing vegetation from the hay piles of nearby pikas. Collared pika over-winter mortality is high and populations are continuing to decrease over time (Morrison and Hik 2007; Franken and Hik, 2004b; Smith et al., 2004). Pikas as the harbingers of global warming.. Pika haypiles and fecal pellets may improve the chances of plant colonization on talus slopes and fertilize soils. gonochoric/gonochoristic/dioecious (sexes separate), Lagomorph Biology: Evolution, Ecology, and Conservation, Max Planck Institute for Demographic Research, "IUCN Red List of Threatened Species", 2008, http://www.springerlink.com/content/n5m1687741615687/. Providing one of the best Barber services, by the best Italians barbers crew in Malta. The word pika is derived from the Siberian name for this animal, puka. Collared pikas rarely forage more than 10 ft (around 3 m) from the talus, a predator-avoidance behavior that creates a distinct grazing-line visible by the end of the summer. having body symmetry such that the animal can be divided in one plane into two mirror-image halves. Iteroparous animals must, by definition, survive over multiple seasons (or periodic condition changes). Sexing is done by investigating their pseudo-cloaca opening for evidence of genetalia. Individual pikas may make several haystacks within their home range and tend to inhabit the same location annually, usually under overhanging rocks, in crevices and along boulders. November 15, 2008 Ochotona collaris. After depositing food they will make one or two territorial calls from hay piles to neighboring pikas. Collared Pika for a sound recording: Yukon.ca/collared-pika. 2004. (Broadbooks, 1965; MacDonald and Jones, 1987; Smith, 2008), Collared pikas exhibit an alternating male-female distribution pattern of home ranges and tend to simply mate with their nearest neighbor (Franken and Hik, 2004b; Smith, 2008). Around 60% of collared pikas are found in regions of Canada, with most of them being in Yukon. Integrated Comparative Biology, 44: 186-193. We explored the behavioural responses of collared pikas to con‐ and heterospecific vocalizations, in order to determine whether they selectively attend to these calls. (Morrison and Hik, 2007; Smith, 2008), Collared pikas are very vocal, with both sexes emitting calls. Adult and juvenile survival is strongly linked to environmental conditions such as climate (Franken and Hik, 2004b). Journal of Animal Ecology, 73: 889-896. Collared pikas live in mountainous terrain with talus slopes and large boulders, which often presents rock slides. (Smith, et al., 2004). 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. Their hind limbs are slightly larger than the front limbs with 5 digits on each forefoot and 4 digits on each hind foot. active during the day, 2. lasting for one day. Plant diversity is typically low and the growing season is short. Adult survival is correlated with the Pacific Decadal Oscillation (PDO), with a time lag of 1 year. Commonly referred to as the \"rock rabbit,\" American pikas are small mammals that inhabit rocky, cold alpine and subalpine areas, typically at elevations of 8,000 to 13,000 feet. 2008. The Collared Pika has already been extirpated in several areas over the last few decades due to changes in habitat conditions. Krajick, K. 1998. Their habitat is characterized as dominantly subalpine and alpine with strong seasonal variations and a short growing season for vegetation (June to August). "IUCN Red List of Threatened Species" They forage close to their home burrows. Demographic analysis of a declining pika Ochotona collaris population: linking survival to broad-scale climate patterns via spring snowmelt patterns.. Journal of Animal Ecology, 76: 899-907. Herbivory meditates grass-endophyte relationships. If insufficient hay reserves are stockpiled in the summer, collared pikas may have to resort to eating lichens and other small plants in underground snow tunnels during winter. Herbivore-Plant-Soil Associations in the Warming Arctic The Pikas. Interannual variation in timing of parturition and growth of collared pika (Ochotona collaris) in the southwest Yukon. (Franken and Hik, 2004a; Franken and Hik, 2004b), Young collared pikas are born blind and nearly hairless. s . young are born in a relatively underdeveloped state; they are unable to feed or care for themselves or locomote independently for a period of time after birth/hatching. However, research on the calls of the closely related American pika indicates that the function of calls is two-fold, serving as a predator alarm as well as in territory defense (Somers 1973, Ivins and Smith 1983, Conner 1985a). Rabbits, Hares and Pikas. During the summer, the pika harvests and cures food to use during the lean months of the winter, as the animals are active year round. Accessed December 09, 2020 at https://animaldiversity.org/accounts/Ochotona_collaris/. In Oregon, American pikas are celebrated residents of Crater Lake National Park, as well as other mountainous areas of central and eastern Oregon. It is important that surveyors recognize the difference between a Hoary Marmot, Arctic Ground Squirrel, and Collared Pika alarm calls. Because it is not easy to distinguish between sexes by sight it is difficult to observe male investment in rearing offspring. Canadian Journal of Zoology, 82: 533-540. the area in which the animal is naturally found, the region in which it is endemic. National Geographic, December: 62-71. The Animal Diversity Web team is excited to announce ADW Pocket Guides! They favor the borders of talus slopes that are closest to meadows and patches of high quality vegetation. As a collared pika prepares to call, it will sit with a hunched back and point its nose upward. This strategy allows full advantage of the best conditions for growth of young. American pikas are the only other pika species in This could lead to a gradual decrease in litter size over the reproductive season due to pre-implantation losses, resorption of embryos, or losses during weaning which results in 2 to 3 young surviving to be weaned. (Broadbooks, 1965; MacDonald and Jones, 1987), Like other pikas, collared pikas are an excellent example of an ecotone species, meaning their home and shelter are separated from their food storage (Broadbooks, 1965). The pika is a small mammal with short limbs, a rotund body, rounded ears, and no external tail. This includes Greenland, the Canadian Arctic islands, and all of the North American as far south as the highlands of central Mexico. Pikas are herbivorous and spend the summer months actively collecting a wide range of vegetation to subsist on during the winter months. Collared Pikas are generalist herbivores that collect two diets during summer. They are mainly solitary, but are sometimes seen in pairs. "Ochotona collaris" (On-line), Animal Diversity Web. Our collared pika population reached its highest density (1.21/ha) in 2007. Topics Synapomorphy of the Bilateria. reproduction in which fertilization and development take place within the female body and the developing embryo derives nourishment from the female. (Broadbooks, 1965; Holmes, 1991; Morrison, et al., 2004), Ochotona collaris is a key species that is consumed by numerous predators. November 15, 2008 The first is consumed immediately, while the second is stored in ‘haypiles’ within the talus matrix for consumption during winter. and across multiple seasons (or other periods hospitable to reproduction). The main threat to the continued survival of the Collared Pika is climate change. (Broadbooks, 1965; Franken and Hik, 2004a; MacDonald and Jones, 1987), Collared pikas most commonly live in mountainous terrain that contains rock slides with large boulders and talus slopes. There are several known carnivorous predators, including ermine, foxes, weasels, lynx, and coyotes. Although they are at times seen in pairs, they are mainly solitary creatures. In some parts of the world, common kusimanse is popular as pet because of its social nature, ability to learn tricks and create strong bond with its owner. Franken, R., D. Hik. Unlike American pikas (Ochotona princeps), which can produce 9 different vocalizations, collared pikas do not have an extensive repertoire. They forage close to their home burrows. at http://www.springerlink.com/content/n5m1687741615687/. All three species often occupy similar or the same habitats. Actually, there are two species of pika: the collared pika found in Alaska and the Yukon and the regular pika found in the Rocky and Sierra Nevada Mountain ranges of Canada and the U.S. As its name implies, the collared pika does have a rather indistinct, light cream colored band encircling its neck behind its ears. Taxon Information Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. Parturition tends to be synchronous. Some researchers increase the probability of detection by playing a recorded whistle call. Danell, K., T. Willebrand, L. Baskin. Pikas increased their vigilance after playback of alarm calls of heterospecific mammals (marmots and ground squirrels), but responded most strongly to conspecific calls. As a collared pika prepares to call, it will sit with a hunched back and point its nose upward. Ochotona species, like other lagomorphs produce two kinds of fecal pellets: hard and soft. Pikas become sexually mature after their first winter and, after a 30-day gestation, produce a litter of 3-4 offspring in a nest located within the talus. Like a rabbit, it snacks, through the long Alaskan summer, on the plants outside its den. 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). ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe. Collared pikas are sensitive to high ambient temperatures and are restricted to high elevation habitats that are declining in response to climate change (Smith et al., 2004). Collared pikas are diurnal and they do not hibernate in winter. Both females and males can breed and produce young at one year of age. American pikas are the only other pika species in North America, and share many life history traits with collared … It can be found in West Africa. 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. 2008. (Franken and Hik, 2004b; Smith, 2008), The peak of the breeding season occurs in May and early June. While ADW staff and contributors provide references to books and websites that we believe are reputable, we cannot necessarily endorse the contents of references beyond our control. There are no known negative effects of collared pikas on humans. Charlene Leininger (author), University of Alaska Fairbanks, Hayley Lanier (editor, instructor), University of Alaska Fairbanks . The timing and amount of snowfall and snowmelt are influenced by the PDO. In birds, naked and helpless after hatching. Accessed having the capacity to move from one place to another. National Science Foundation Found around the world at elevations of more than 20,000 feet, the pika is one of the most resilient beasts around. They have a common ano-genital opening, similar to birds, that is considered a pseudo-cloaca (MacDonald and Jones, 1987; Broadbooks, 1965). They have hairy plantar surfaces on the feet. The call of a pika is unmistakable once it has been heard. ("IUCN Red List of Threatened Species", 2008; Smith, et al., 2004), The monogeneric family Ochotonidae comprises about one third the diversity of the Order Lagomorpha. The Animal Diversity Web is an educational resource written largely by and for college students. Ecology and distribution of the pikas of the Washington and Alaska.. American Midland Naturalist, 73(2): 299-335. Collared pikas, along with other herbivorous mammals like hoary marmots (Marmota caligata) impact grass and herbaceous plant species in their high elevation habitats (Koh and Hik, 2007). Foraging distance varies according to degrees of predation risk (Holmes, 1991; Morrison et al., 2004). Although, some species of pikas have be known to have post-partum estrous and produce a second litter per year further research is need to investigate if this is true for O. collaris. Collared pikas have a call that sounds like a recurring single sharp note with each series varying in loudness and is similar to the American pika’s short call. 14-26 in J Chapman, J Flux, eds. However, there are two species of Pika that live in North America. Common kusimanse lives near the water. Predator risk affects foraging behavior of pikas: observational and experimental evidence.. Collared pikas are considered facultatively monogamous because most males are unable to control enough territory to gain access to multiple females. offspring are produced in more than one group (litters, clutches, etc.) Collared pikas reach adult size in 40 to 50 days. Morrsion, S. 2006. Collared pikas have a call that sounds like a recurring single sharp note with each series varying in loudness and is similar to the American pika ’s short call. An animal that eats mainly plants or parts of plants. Disclaimer: There is one designatable unit for Collared Pika … Collared pikas often colonize taluses that are on southwest facing slopes because they tend to have shorter period of snow cover and a longer plant growing season (Franken and Hik, 2004a). Contributor Galleries Lagomorph Biology: Evolution, Ecology, and Conservation. Holmes, W. 1991. Leininger, C. 2009. (Broadbooks, 1965; Krajick, 1998), Collared pikas have no natural defense against predators besides hiding in cracks, crevices, and under large boulders in talus. Koh, S., D. Hik. Morrison, S., L. Barton, P. Caputa, D. Hik. Female collared pikas are responsible for most of the parental investment and bear the brunt of energetic constraints of gestation and lactation. Pikas rarely forage more than 10 m from talus into meadows to collect food (Morrison, 2006). Collared pikas vocalize frequently during hay gathering. Franken, R., D. Hik. Foraging ecology and population dynamics of collared pikas in southwestern Yukon.. Arctic, 59(1): 104-107. (Danell, et al., 1998; Smith, et al., 1990). at http://www.consecol,org/vol2/iss2/art9. Both territorial and predator calls produced sound approximately the same (Trefry, Ochotona thesis 2008). Parturition dates vary among years in response to the highly seasonal habitat. They have been characterized as being asocial, and as such are extremely defensive of their territories. The Collared Pika’s Canadian range is fairly remote and, as such, human activity has a minimal impact on the species. Help us improve the site by taking our survey. Species, 41: 4-5. Grants DRL 0089283, DRL 0628151, DUE 0633095, DRL 0918590, and DUE 1122742. A low snow-pack year could expose collared pikas and their stored food to freezing ambient temperatures, but an earlier snowmelt could lengthen the growing season and allow more time to feed and store food for the next winter (Smith et al. Convergent in birds. Geographic Range. They consume their soft pellets to reduce the loss of nutritional value in their food. (Franken and Hik, 2004b; Morrison and Hik, 2007; Smith, et al., 2004), Collared pikas can have a relatively long lifespan, up to 6 to 7 years (Smith, 2008). They do not burrow but instead take shelter within their talus habitats. The most diagnostic characteristic of the collared pikas is the creamy-buff fur patch over the facial gland which differs from their close relative, American pikas (Ochotona princeps), which has a brown patch. (Koh and Hik, 2007), Collared pikas are interesting and unique members of their alpine habitats. living in the Nearctic biogeographic province, the northern part of the New World. Instead, they are known to take shelter within their talus habitats. (Franken and Hik, 2004b; Holmes, 1991; Morrison and Hik, 2007; Morrison, et al., 2004; Morrsion, 2006; Smith, 2008), Collared pikas live in low densities (2 to 15 individuals/ha) with a home range about 25 to 30 m in diameter (Morrison and Hik, 2007; Smith, 2008). Collared pika in Denali National Park, AK. They also consume fecal pellets of other species such as hoary marmots (Marmota caligata) and ermine (Mustela erminea) (Broadbooks, 1965). 2007. However, male reproductive success depends on gaining habitat and attracting females (Franken and Hik, 2004b). Additional support has come from the Marisla Foundation, UM College of Literature, Science, and the Arts, Museum of Zoology, and Information and Technology Services. Roughly the size of a fist, the pika tends to be underestimated amongst hikers and climbers, though this should not be the case. Closely related to hares and rabbits, pikas are charismatic but lesser known members of the order Lagomorpha. Collared pikas are diurnal and do not hibernate during the winter. Although collared pikas belong to the Ochotonidae species, unlike many other of that group they do not burrow. Search in feature Biology. animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Collared pikas have no natural defense against predators besides hiding in cracks, crevices, and under large boulders in talus. Influences of habitat quality, patch size, and connectivity on colonization and extinction dynamics of collared pikas Ochotona collaris. There are distinctive patches on the nape and shoulder forming a collar thus giving them their common name. Accessed In North America, they also are called "rock rabbits," "coneys," and "little chief hares." They also have been recorded inhabiting areas near sea level in southern Alaska and British Columbia (MacDonald and Jones, 1987; Broadbooks, 1965). Animals with bilateral symmetry have dorsal and ventral sides, as well as anterior and posterior ends. MacDonald, S., C. Jones. 2004. Mammalian Species, 281: 1-4. Outside Canada, Collared Pikas occur in southern and central Alaska. having markings, coloration, shapes, or other features that cause an animal to be camouflaged in its natural environment; being difficult to see or otherwise detect.

It can be heard over a considerable distance. Sarus cranes (Grus antigone) are located in northern India, southeast Asia, and in the northern parts of Australia.Most sarus cranes are widely distributed along the Gangetic plain and in eastern Rajasthan in the northern states of India. 2007. Collared pikas, however, disperse shortly after weaning in order to find a vacant territory (Morrison & Hik 2007). The dental formula is; I 2/1 with 2nd peg like incisors, C 0/0, P 2/3, M 2/3 (MacDonald and Jones, 1987). Pikas defend individual territories (about 15-25 m radius) and have a promiscuous mating system. collared pika (Ochotona collaris) is the only species of pika found in Alaska. The ADW Team gratefully acknowledges their support. (On-line). American pika indicates that the function of calls is two-fold, serving as a predator alarm as well as in territory defense (Somers 1973, Ivins and Smith 1983, Conner 1985a).
