Mountain bluebird The mountain bluebird ("Sialia currucoides") is a medium-sized bird weighing about 30 g with a length from 16 - . They have light underbellies and black eyes. Adult males have thin bills and are bright turquoise-blue and somewhat lighter underneath. Adult females have duller blue wings and tail, grey breast, grey crown, throat and back. In fresh fall plumage, the female's throat and breast are tinged with red-orange, brownish near the flank contrasting with white tail underparts. Their call is a thin 'few'; while their song is warbled high 'chur chur'. It is the state bird of Idaho and Nevada. It is an omnivore and it can live 6 to 10 years in the wild. It eats spiders, grasshoppers, flies and other insects, and small fruits. The mountain bluebird is a relative of the eastern and western bluebirds.
Channel Islands spotted skunk The Channel Island spotted skunk ("Spilogale gracilis amphiala") is an insular endemic carnivore and a subspecies of the western spotted skunk ("Spilogale gracilis"). Little is known about their exact variations from the mainland spotted skunk and variations between locations, resolution of which awaits further genetic and morphologic evaluation. The skunk is only currently found on two islands off the southern coast of California (Santa Cruz Island, and Santa Rosa Island, where its occurrence was once thought to be rare but recently experienced a population surge in the 1990s). Its presence has been recorded on San Miguel Island, but it has since been declared extinct in that area. The Channel Island skunk is one of two terrestrial carnivores on the islands, the other being the island fox. It is designated as a "species of special concern" by the state of California.
