Some live only in pairs as adults, others like American crows, can have extended family groups on one territory, others, like fish crows, live in larger groups of unrelated birds of many ages ...
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, such as barred owls.

The syrinx enables some species of birds (such as parrots, crows, and mynas) to mimic human speech. Unlike the larynx in mammals, the syrinx is located where the trachea forks into the lungs.

Crows, along with other members of the Corvidae family, are some the smartest animals on Earth. A new study shows that crows, in this case the carrion crow, can count out loud just like human ...
