Their habitat is characterized as dominantly subalpine and alpine with strong seasonal variations and a short growing season for vegetation (June to August). Pikas are active during the day, it spends most of the day looking for food, guarding it's territory and watching for predators. The appearance of collared pikas is similar to other members of the genus Ochotona. 36), Zgurski, Jessie Marie. [8] There have five digits on each front foot and only 4 on each hind foot. A pika (/ ˈ p aɪ k ə / PY-kə; archaically spelled pica) is a small mountain-dwelling mammal found in Asia and North America. Juveniles will disperse within the natal talus patch immediately following the end of gestation to make their own territory (Franken and Hik, 2004a). “PHYLOGEOGRAPHY, ECOGEOGRAPHIC VARIATION, AND EVOLUTIONARY HISTORY OF THE COLLARED PIKA [OCHOTONA COLLARIS.”, MacDonald, Stephen O. and Jones, Clyde. Smith, A. T. 1978a. About LDT; Taxonomy Tees! “COLLARED PIKA (OCHOTONA COLLARIS) OCCUPANCY IN TOMBSTONE TERRITORIAL PARK, YUKON.”, Morrison, Shawn, Barton, Luc, Caputra, Peter, Hik, David S.. 2004. Females have up to two litters a year that range between 2 to 6 young each and average 2.2 individuals weaned. As they do not hibernate, pikas gather cuttings of preferred plants, cure them in sheltered, sunny places, and store … [8] This species is often kleptoparasitic and takes food from others. MAINTENANT DISPONIBLE EN FORMAT CARTE DE SOUHAIT! [8] This indicates no sexual dimorphism; consequently, one must examine the pseudo-cloaca for evidence of specific genitalia to distinguish the sex of the collared 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. Species Ochotona collaris collared pika. When it comes to their feet, they have hairy plantar surfaces. Breeding season: Breeding occurs from May to June. [9] It spends no time burrowing because it uses its talus site as a means of protection and habitation. Accessed October 03, 2014 at. "Ochotona collaris" (On-line), Animal Diversity Web. [14] However, the pinnacle of the mating season arises in the summer in May and early June. The call is a single, piercing note that sounds like “ank” or “ink” and can be heard for several hundred yards. 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. Collared Pika. However, male reproductive success depends on gaining habitat and attracting females (Franken and Hik, 2004b). [8] While some mammals have reduced clavicles in order for more range of motion, the collared pika has a well-developed clavicle supporting the scapula. Parturition tends to be synchronous. [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 that of O. The days grow shorter until the sun doesn’t come out at all. 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). They also consume fecal pellets of other species such as hoary marmots (Marmota caligata) and ermine (Mustela erminea) (Broadbooks, 1965). They favor the borders of talus slopes that are closest to meadows and patches of high quality vegetation. As compared to their front limbs, their hind limbs are somewhat larger, and they have five digits on each forefoot and four on each hindfoot. NOW AVAILABLE AS A CARD! 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. Menu and widgets. [8] Collared pikas tend to have multiple haystacks of vegetation throughout their home range and often dwell in the same site annually. Observations: Little is known about the longevity of these animals. Collared pikas are considered facultatively monogamous because most males are unable to control enough territory to gain access to multiple females. collared pika calls transmit with less degradation across their own species' habitat than the habitat of their congener. [16] Upon finding some asynchronous breeding among pikas, it was suggested that due to not being able to predict snowmelt, this type of breeding could ensure some success in breeding. [11] Although both can reproduce at one year of age, the male’s reproductive success is reliant on acquiring habitat and drawing females. [8], The estimated population density is roughly around 6.4 to 7.2 individuals per hectare. Collared pikas are rather small in size, reaching around only 5.5 ounces in adulthood, and have a concealed tail and short round ears. Ochotona dauurica: information (1) Species Ochotona hyperborea northern pika. Adaptations, Defences, and Behavior; Habitat and Range; Life Cycle; Diet; Species Survival Status; Sites Used; Video; Physical Characteristics of the American Pika. 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). “The mating system, dispersal behavior and genetic structure of a collared pika (Ochotona collaris: Ochotonidae) population in the southwest Yukon, and a phylogeny of the genus Ochotona.”. A pika is a very vocal animal. Their hind limbs are slightly larger than the front limbs with 5 digits on each forefoot and 4 digits on each hind foot. Adaptations: To live through the alpine winter, because they do not hibernate, the pikas gather food, grasses mostly, to store for the winter. Pika haypiles and fecal pellets may improve the chances of plant colonization on talus slopes and fertilize soils. Two species are known in Canada; 18 worldwide. 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). [9] During the cold winters, the collared pika does not hibernate, but instead stays active, counting on their food sources for energy and survival, and uses the snowpack as a means of insulation. Italian's Barber Shop where do pikas live - Located in Triq Birkirkara San Gwan. [3] It is a small (~160 gram) 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. [8] Each individual within this species will preserve its own territory and its own vegetation cache or haypile, and defend it with full force. [9] However, although it has multiple haystacks, it mainly focuses on one while the others are much smaller and localized caches. A pika, archaically spelt pica, is a small-sized mountain-dwelling mammal native to Asia and North America. In Oregon, American pikas are celebrated residents of Crater Lake National Park, as well as other mountainous areas of central and eastern Oregon. Foraging Behavior: stores or caches food. [10] The food caches have been seen to be similar to the size of location of storage. Collared pikas reach adult size in 40 to 50 days. They are mainly solitary, although they may be seen in pairs occasionally. [16], Collared pikas are a fairly vocal species. Contact Us; Gallery; Find an Episode!

They also have been recorded inhabiting areas near sea level in southern Alaska and British Columbia (MacDonald and Jones, 1987; Broadbooks, 1965). It uses both song and call vocalizations. [8] 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. [3] This species is known as an ecotone species for the way that it keeps its shelter and food storage separate from each other. Colored pikas minimize their exposure to extreme ambient temperatures by seeking shelter in piles of boulders adjacent to alpine meadows. Your Thirty Minutes of Interesting Animal Info. [10], Ochotona collaris has been classified under 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 Special Concern. Collared pikas share common characteristics with other Ochotona species, such as their small size (around 160 g), short round ears, and a concealed tail (Smith, 2008). It has large rounded ears, and no visible tail. Step 2, specify recipient of certificate. [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 therefore it is important to note patterns between closely related species, such as the collared pika and the American pika. [3] This gap encompasses both British Columbia and Alberta, Canada. [8] They range between 130 to 200 g in body mass and 17.8 to 19.8 cm in length. Female collared pikas are responsible for most of the parental investment and bear the brunt of energetic constraints of gestation and lactation. [12] 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 Richardson Mountains, south into northwestern British Columbia and west close to the Mackenzie River of the Northwest Territories. Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; viviparous. These little mammals have stout bodies, short legs, and small ears. [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. Collared pikas are diurnal and do not hibernate during the winter. Average age at sexual or reproductive maturity (male): 1 years. [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. Life, Death, and Taxonomy. princeps. 2004; Morrison and Hik, 2007). The timing and amount of snowfall and snowmelt are influenced by the PDO. [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. On the dorsal side of their bodies, they have dull grayish fur with gray patches on their shoulders and nape creating a distinguishable collar, while on the ventral side they have an opaque white-colored fur. Their sharp, curved claws help them climb from rock to rock with ease. With short limbs, very round body, and even coat of fur, and no external tail, they resemble their close cousin the rabbit, but with short rounded ears. [8] In 1973, it was suggested that during the isolation of the Wisconsin glaciation, O. collaris became its own species separate from O. It has a small rounded body and brownish fur. [3] Therefore, the collared pika is seen as an asocial species and prefers solitude. There is no discernable size difference between … 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; consequently, they only have one annual molt. IUCN Red List of Threatened Species: least concern. Pikas are one of the few mammals in the lower 48 states that can survive their entire lives in alpine terrain, the windswept no-man's-land above tree line. Boulders provide protection from the sun, rain, wind, and fluctuations in air temperature. 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. To survive the desolate Alaskan winter one little botanist will turn to an unlikely tool to maintain the balance of life, death, and Taxonomy. There are a variety of species, all of which come in different shapes and sizes. [12] Consequently, collared pikas are one of the pika species that has been recognized as an indicator species for the effect of climate change on alpine ecosystems. The Alaskan Winter is harsh. Snow-pack is important in insulating pikas from temperature extremes during winter months. 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. Other Physical Features: endothermic ; homoiothermic; bilateral symmetry. Rocky Mountain pika (Ochotona princeps) is found throughout the Rocky Mountains in BC and Alberta. Also, numerous birds of prey such as eagles and owls will hunt collared pikas (Broadbooks, 1965; Holmes, 1991; Morrison et al., 2004). collared pika calls showed more similarity than expected given that they are distinct, allopatric species. [14], Collared pikas generally mate with those closest to them or 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 based on the fact that males often travel to territories of several females during the spring before mating season begins. [8] Parturition timing for northern alpine herbivores is vital due to the brief snow-free timeframe and lack of food sources. 2011. Pikas have fur-covered feet, but bare toe pads. Parturition dates vary among years in response to the highly seasonal habitat. [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.
