The American crow or Corvus brachyrhynchos is a large passerine bird species of the family Corvidae.

The most common arrangement (for birds) is anisodactyl, with three toes pointed forward and one backward. The toe that points back is commonly called the hallux. Crows have an anisodactyl arrangement.

Crows have strong, sharp claws that are well adapted for grasping and holding on to prey. Their feet have three toes facing forward and one facing backward, which allows them to grasp and hold onto objects with great dexterity. They are a perching bird and have two strong backward pointing toes. Crows have rough feet and leave a “jointed” print.

It is a common bird found throughout much of North America. American crows are the New World counterpart to the carrion crow and the hooded crow of Eurasia; they all occupy the same ecological niche.

Although the American crow and the hooded crow are very similar in size, structure and behavior, their calls and visual appearance are different.

From beak to tail, an American crow measures 16–20 in., almost half of which is tail. Mass varies from about 11 to 21 oz., with males tending to be larger than females.

The American crow or Corvus brachyrhynchos plumage is all black, with iridescent feathers. It looks much like other all-black corvids.

They are very intelligent, and adaptable to human environments. The most usual call is CaaW!-CaaW!-CaaW! They can be distinguished from the common raven because American crows are smaller and the beak is slightly less pronounced. American crows do not hunch and fluff their throat feathers when they call.

Crows are some of the smartest animals in the world, with their intelligence considered on par with chimpanzees. One of the most famous examples of one sign of intelligence is tool use.

This behavior has been recorded in several other species of Corvus as well. Examples of tool use in American Crows include a captive individual dipping a cup in some water to moisten a container of dry food and a wild crow ripping off a splinter of wood from a fence to try to spear some prey in a hole.

American crows are common, widespread, and susceptible to the West Nile virus, making them useful as a bioindicator to track the virus’s spread. Direct transmission of the virus from crows to humans is impossible.

They are considered an agricultural pest, and are subject to hunting and management.

A 2012 genetic analysis of the genus Corvus by Knud A Jonsson and colleagues using nuclear and mitochondrial DNA calculated that the American crow diverged from a lineage that gave rise to the collared, carrion and hooded crows around 5 million years ago.
