I live in Massachusetts, which is part of New England, in the Northeast section of the United States. We have a large number of birds I identify as crows, and only crows. I've heard of ravens, but thought they were mainly found in Europe and other countries in that region of the world.
A friend recently told me that, although there are other species of crows, those I see most frequently are probably called the American Crow. She also said the Common Raven, which looks similar to that crow, lives year-round in a large portion of the United States, including New England.
Now that I know ravens exist here, I'd like to know if I've seen them, or are fortunate enough to have some living in my yard.
In terms of physical characteristics, behavior, diet, or other factors, how can I tell the difference between the American Crow, and the Common Raven that lives in America?
