: Corvus dauuricus: Daurian Jackdaw Family: Corvidae (), Length: 32cm.,,The Daurian Jackdaw (Corvus dauuricus) is a member of the Corvidae or crow family of birds. It is closely related to the Eurasian Jackdaw. The name derives from the Dauria region of eastern Russia. It is the same size or perhaps slightly smaller (32 cm in length) than the latter species, with the same proportions and identical habits. The principal difference is its plumage; many but not all adults of this species have large areas of creamy white on the lower parts extending up around the neck as a thick collar. The head, throat, wings and tail are glossy black and the ear coverts are grizzled grey. Darker adults and young birds resemble Eurasian Jackdaws, though Daurian Jackdaws have a black iris, unlike the distinctive grey-white iris of the Eurasian Jackdaw.

Summary[edit] Description: -Photo by Simon Wray, Oregon Department of FIsh and Wildlife Clark's Nutcracker (Nucifraga columbiana) On his historic expedition with Meriwether Lewis, Captain William Clark, the bird's namesake, first mistook this species for a woodpecker undoubtedly because of its long, sharp beak. However, this most specialized member of the North American Crow family uses this apparatus to pry loose its favored seeds from unrelenting cones of several pines, with which the nutcracker has a symbiotic relationship. The whitebark pine, in particular, is totally reliant on Clark's Nutcrackers for seed dispersal and germination. In Oregon the Clark's Nutcracker is a resident along the crest of the Cascades, usually above 4,000 feet, lower on the east slope, from the Columbia River south to the California border, west into the Siskiyous, and east to the Warner Mountains, northeast throughout the Blue and Wallowa mountains. It is very common at Crater Lake. Date: 11 May 2012, 13:18. Source: clarks_nutcracker_2_wray. Author: Oregon Department of Fish & Wildlife.
