Corvus brachyrhynchos
The American Crow (Corvus brachyrhynchos) is a large passerine bird species of the family Corvidae. It is a common bird found throughout much of North America. In the interior of the continent south of the Arctic, it is simply called "the crow", as no other such birds occur there on any regular basis. It is one of several species of corvid that are entirely black, though it can be distinguished from the other two such birds in its range—from the Common Raven (C. corax) by size and behavior and from the Fish Crow (C. ossifragus) by call (but see below). It is also distinguished from the Raven by its smaller, more curved bill than the parallel bill of the raven, and its squared tail. American Crows are common, widespread and adaptable, but they are highly susceptible to the West Nile Virus. They are monitored as a bioindicator. Direct transmission of the virus from American Crows to humans is not recorded to date, and in any case not considered likely. Although both the American crow and the Hooded crow strongly resemble in size, structure and behavior, their calls are different. The American crow nevertheless occupies the same role the hooded crow does in Eurasia.The American Crow is a distinctive bird with iridescent black feathers all over. Its legs, feet and bill are also black. They are 40–50 cm (16–20 in) in length, of which the tail makes up about 40%. Each wing is around 27–34 cm (11–14 in) long. The bill length is on average 5 cm (2 in), varying strongly according to location.[4] Males tend to be larger than females.[7] The most usual call is a loud, short, and rapid caaw-caaw-caaw. Usually, the birds thrust their heads up and down as they utter this call. American Crows can also produce a wide variety of sounds and sometimes mimic noises made by other animals, including other birds.
American Crows are highly adaptable and will live in any open place that offers a few trees to perch in and a reliable source of food. Regularly uses both natural and human created habitats, including farmland, pasture, landfills, city parks, golf courses, cemeteries, yards, vacant lots, highway turnarounds, feedlots, and the shores of rivers, streams, and marshes. Crows tend to avoid unbroken expanses of forest, but do show up at forest campgrounds and travel into forests along roads and rivers. Avoids deserts.
