American Pika

American Pika

Latin name: Ochotona Princeps,
Conservsation status: least concern (population is decreasing)

Pikas, also called "whistling hares" because of their loud song, feed in winter on dried haypiles they have stored near the entrance to their burrows. When haying during late summer they may make up to 100 trips a day.

Pikas live primarily in cool micro-climates on rocky slopes, feeding in adjacent meadows. Warmer temperatures and reduced snowpack are the main threats. Some Pikas may move to higher, cooler regions if there is enough vegetation. Pikas living in lower, warmer regions are at risk if they attempt to move to other regions as they are extremely sensitive to heat—more than two hours in temperatures over 78 °F can be lethal. Without enough winter snow for insulation, Pikas will freeze.


Other animals at risk

Polar Bear
Polar Bear
Polar Bears live only in the Arctic. Loss of sea ice has a critically adverse effect on Polar Bears. They hunt from the edge and build snow dens on the ice for resting and raising their cubs. Sea ice decline could open the Arctic to shipping and tourism, further disturbing Arctic habitats. Other threats are oil development and industrial pollution that reaches the Arctic through air and ocean currents.
Monarch Butterfly
Monarch Butterfly
The annual North American migration of the Monarch is listed as a "threatened phenomenon." Climate related threats include: drought, storms, changes in precipitation and dependence on temperature to trigger migration and reproduction. The Monarch feeds and lays eggs exclusively on milkweed plants, so it is also highly vulnerable to herbicides and habitat destruction.
Emperor Penguin
Emperor Penguin
In 50 years, the mean temperature of western Antarctica has risen nearly 3 °C—more than any other region—reducing the extent and thickness of winter ice. The Emperor Penguin is dependent on the ice for breeding, raising chicks and moulting. Less sea ice decreases zooplankton (krill) which feed on algae that grow on the underside of the ice. Krill are an important part of the food web for the Emperor and other Antarctic marine species.
Arctic Fox
Arctic Fox
The Arctic tundra is a region of shrubs, grasses and permanently frozen subsoil. Warming could change the tundra to boreal forest—habitat for the Red Fox. The Red Fox, a predator and a competitor for food, is already beginning to migrate north into the Arctic Fox's territory. Milder tundra weather also causes changes in the population of lemmings and rodents—main food for the Arctic Fox.
