One of the most numerous birds on the continent, the American Crow is easily recognized. Although they have a rather dull appearance, there is much more to this bird that meets the eye. Crows are very social- flocks sometimes contain up to a million birds. They're inquisitive and smart, good learners and problem-solvers. They're also aggressive enough to chase away larger birds like hawks, owls and herons.
Young American Crows do not breed until they are at least two years old, and most do not breed until they are four or more. In most populations the young help their parents raise young for a few years. Families may include up to 15 individuals and contain young from five different years.
The wide-ranged diet of the American Crow includes grains, seeds, nuts, fruits, berries, small animals such as mice, eggs and nestlings of other species, earthworms, small aquatic animals and a vast range of insects. They will also raid garbage cans and infrequently eat carrion. The birds are a dread to farmers because they can cause tremendous crop damage.
Crows will steal dog food as well- I watched this one sneak into my neighbors yard and help himself to some kibbles 'n bits. Apparently, he hasn't been introduced to the huge, intimidating resident dog (I have and immediately knew that we disliked each other).
