American crow (Corvus brachyrhynchos)

About the Bird

American crows can be found in the Decorah area year-round, although some wintering crows could be migrants from colder northern areas. They eat everything: grains, seeds, nuts, fruits, berries, insects, worms, fish, young turtles, mice, crayfish, mussels, clams, the eggs and nestlings of other birds, carrion, and garbage.

Both members of a breeding pair help build the nest, and young birds from the previous year sometimes help as well. They build stick nests with an inner cup lined with pine needles, weeds, soft bark, and hair. American crows lay three to nine eggs per clutch and produce up to two broods per year. They incubate eggs for 16-18 days and young stay in the nest for 28-35 days prior to fledging. To learn more, visit Cornell’s website.
