	Crow (bird) - Search View - MSN Encarta
		Crows in turn may be mobbed by other birds, because their omnivorous diet includes eggs and nestlings as well as other small animals, vegetable matter, carrion, and garbage.
		The American crow is up to 50 cm (up to 20 in) long and has an average lifespan of approximately 15 years in the wild.
		The American crow is classified as Corvus brachyrhynchos, the northwestern crow as Corvus caurinus, the fish crow as Corvus ossifragus, and the Mexican crow as Corvus imparatus.

	Crow - Wikipedia, the free encyclopedia
		Crows, and especially ravens, often feature in legends or mythology as portents or harbingers of doom or death, because of their dark plumage, unnerving calls, and tendency to eat carrion.
		In mythology and folklore as a whole, crows tend to be symbolic more of the spiritual aspect of death, or the transition of the spirit into the afterlife, whereas ravens tend more often to be associated with the negative (physical) aspect of death.
		Crows in the northwestern US (a blend of Corvus brachyrhynchos and Corvus caurinus) show modest linguistic capabilities and the ability to relay information over great distances, live in complex, hierarchic societies involving hundreds of individuals with various "occupations", and have an intense rivalry with the area's less socially-advanced ravens.

	Northwestern Crow - Wikipedia, the free encyclopedia
		The Northwestern Crow (Corvus caurinus) is very similar to the more western forms of the American Crow (Corvus brachyrhynchos) but it is slightly smaller (33-41 cm in length) and has proportinately smaller feet with a slightly more slender bill.
		It is the calls that are significantly different and often serve to identify it.
		It is a typical crow nest with 4-5 eggs usually laid.

	Crow
		The crow (Corvidae) is a large family of birds that includes jackdows, choughs, JAYS, MAGPIES and nutcrackers as well as crows and RAVENS.
		The crow family represents one of the most advanced stages of avian evolution, showing, for example, a highly developed intelligence and a complex social organization.
		The northwestern crow nests mainly in coniferous trees; the American crow, in deciduous and coniferous trees and, occasionally, in low bushes.

	Life History of the Crow: Crows.net Project.
		The American crow is a fairly large bird, 17 to 21 inches from bill to tail (43-53 cm), with the mean weight for males 458 grams and for females, 438 grams.
		Northwestern Crow The Northwestern Crow, Corvus caurinus is nearly indistinguishable visually from the American crow, although it is somewhat smaller, ranging from 33 to 41 cm.
		Young crows will be completely dependent upon their parents for food for a couple of weeks after leaving the nest and it may be three or four months before they are completely able to obtain all of their food themselves.

		Northwestern Crow is resident along the Pacific coast from south-coastal and southeastern Alaska south through British Columbia west of the Coast Mountains and Cascade Mountains, to northwestern Washington, including the Queen Charlotte Islands, Vancouver Island, and all other coastal islands.
		Although the Northwestern Crow is widespread along the coast, its centre of abundance is in the Georgia Depression, including the southeast coast of Vancouver Island and the lower Fraser River valley.
		With the exception of one report of a crow banded near Comox on 11 June 1979 and recovered north of Victoria on 26 November 1980, all recoveries (n = 38) of the Northwestern Crow were from the banding location, some after a number of years had passed.

	Consumption and Caching of Food in the Northwestern Crow (Corvus Caurinus) (Site not responding. Last check: 2007-11-05)
		The Northwestern Crow (Corvus caurinus) exhibits a natural daily rhythm in foraging mode, feeding at high tide when food is less available, and provision- ing food to cache sites at low tide (James and Verbeek 1983).
		Crows ingested these pieces when feeding, but when provisioning held them in the beak and throat, trans- porting them into the nearby forest where the pieces were cached.
		These calculations revealed that crows could feed at a rate of 5.3 W in patch A, and 4.3 W in patch B. Provisioning crows gathered a load of (almost al- ways) three pieces and made a trip to the forest to cache the pieces before returning to collect another load.

	Controlling bird damage by American Crows (Corvus ossifragus) by Ron Johnson
		Crow pairs appear to remain together throughout the year, at least in nonmigratory populations, and pairs or pair bonds are likely maintained even within large winter migratory flocks.
		In a recent study in California, crows were successfully dispersed from urban crow roosts using tape-recorded “squalling” calls (given by a crow struggling to escape from a predator) and a portable tape player commonly used by hunters to attract animals.
		To prevent hooded crow escape, the ladder gap width of the American model was reduced from 18 to 12 inches (45 to 30 cm), and 1.5 x 0.8-inch (4 x 2-cm) square rungs were used instead of 3-inch (8-cm) diameter metal rods.

		The main difference is that the Northwestern Crow lives on the coast preferring to be close to the shores of salt water, where the American crow is more of an open country interior bird.
		Crows can often be seen dropping nuts and shells from high elevations onto hard surfaces, such as rocks or pavement, in order to brake them open.
		The Northwestern Crow usually nests in a vertical fork of both coniferous and deciduous trees.

	WDFW -- Landscaping for Wildlife
		Crows and ravens belong in the Corvid family (which includes jays and magpies) and are considered to be among the most adaptable and intelligent birds.
		Ravens have wedge-shaped tails and crows have fan-shaped tails.
		Crows occupying the center of the roost are less exposed to predators and weather than those on the edges or those roosting alone.

	Lewis and Clark as Naturalists
		Northwestern crows inhabit the coastal lowlands of the Pacific Northwest, only moving inland along major rivers during salmon runs.
		Northwestern crows can be seen cracking open shellfish by dropping them from the air onto rocks below, much as seagulls do.
		Lewis made a point to say the crows he observed along the Columbia estuary were smaller than the usual crows he saw across the country (American crows), but otherwise the same species.

	uwnews.org \| Crows alter their thieving behavior when dealing with kin, other birds \| University of Washington News and ...
		Researchers at the University of Washington have found a species of crow that distinctly alters its behavior when attempting to steal food from another crow, depending on whether or not the other bird is a relative.
		The Northwestern crow (Corvus caurinus) uses a passive strategy when it attempts to take food from kin but becomes aggressive when it tries to steal a morsel from a non-related crow.
		To understand crow behavior, the UW researchers captured and banded 55 birds that foraged in a suburban Snohomish County park along Puget Sound north of Seattle.

	West Nile virus' spread threatens Bay Area crows / Birds show high susceptibility -- toll may emerge next year (Site not responding. Last check: 2007-11-05)
		Just as the surge in crow populations is beginning to raise concern among ornithologists of possible downward pressures on other bird populations through nest predation, a new threat to crows looms.
		Crows are apparently particularly susceptible to West Nile, but it's not clear whether their relatively large size and inclination to live near people have meant that disproportionately high numbers of their bodies have been collected as indicators of the virus' spread, or whether West Nile is frighteningly deadly across a wide spectrum of bird species.
		It's thought that even the 57,000 dead crows collected between 1999 and 2002 may represent only a fraction of the crows killed by the virus.) So it's unclear whether crows are particularly susceptible to West Nile or North American birds (and perhaps other animals) are generally under siege by a pandemic.
