The American crow, Corvus brachyrhynchos, of the family Corvidae exists as a common and widespread species throughout Maine, as well as almost all of North America. Animal behaviorists consider crows to be among the world's most intelligent animals, with some species capable of tool use and construction.
American crows measure approximately 20 inches in length, have a wingspan around 36 inches and weigh between 12 to 22 ounces.American crows are easy to identify, having brilliant iridescent black feathers, black legs, feet and bill. From a distance, the American crow can sometimes be mistaken for the common raven. A discriminating eye looks for the raven’s larger size, heavier bill, feather tufts at the neck and wedge-shaped tail feathers in flight.
The American crow’s diet includes small mammals, other birds, insects, fruits, earthworms, seeds, frogs, eggs, and carrion. The most usual sound made by the American crow is a loud caw-caw-caw, but this crafty and wise avian can also produce a wide variety of sounds, sometimes mimicking noises made by other animals.

Interesting! I never would have guessed that crows are considered to be among the world's most intelligent animals! I guess that's why they always manage to fly away at the last minute before becoming road kill. And tool use?! If you catch any tool action on those game cameras of yours, please post! =)
