Birds
editHabitats surround this high-elevation mountain area with low-growing seasons; the cold freezes many lakes and plants, restricting their access to food and water.[1] This climate would render it impossible for many bird species to survive.
In this range, horned larks (registered as endangered since July 14, 2005[2]) and American pipits live in alpine habitats, announcing their arrival as snow melts and departing before the snowfall begins[1]. Horned larks are sandy to rusty brown,[3] while American pipits are small with a grey top and stripped bottom.[4] Other species, like White-tailed ptarmigan, are endemic to the mountains, where they have designated the southern limit.[1] Among the species that can adapt to high elevations are the Franklin’s, blue and ruffed grouse, red crossbills, white-winged crossbills, gray jay, Steller’s jay, and pine grosbeaks.[1] Whitebark pine (registered endangered since June 20, 2012[5]) can be eaten by Clark's nutcrackers, whose seeds are harvested from the pine.[6]
The gyrfalcon, the northern harrier and red-tailed hawk, the Swainson's hawk, the bald eagle, and the golden eagles are predators that serve different prey-predator relationships.[1] Golden eagles, distributed equally throughout the world,[7] surprise attack their prey to feed on s mall mammals and larger prey such as marmots, ground squirrels, seals, and coyotes.[8] Other species like the Great gray owl, great horned owl, three-toed, black-backed, pileated, and hairy woodpeckers are common in the mountain all year round[1].
Insects
editThere are few insect databases available; some relevant insect populations are the Bristly tachinid flies, Flower flies, Sarcophagid flies, Blow files, Swallowtail butterflies, and ladybird beetles.[1] Mountain tops are crowded with insects during mating season, where they stay for only a moment before returning to their preferred habitats.[1] The ladybird beetle hibernates in elevated and warm areas to avoid the cold throughout the winter.[9]
Mountain pine beetles create adversities with the lodgepole tree population. Pine trees in British Columbia are experiencing a pine beetle invasion on a landscape level.[10] Lodgepole pine trees are attacked by these beetles yearly, and their larvae build up inside the trees.[1] Over time, healthier trees are becoming increasingly difficult to compete with mountain pine beetles.
