Every continent except
South America has at least one familiar roadside crow, and this is the
species in North America. It is almost impossible to go into the countryside
without seeing these birds along highways or flying overhead. Intelligent,
wary, virtually omnivorous, and with a high reproductive capacity, the
American Crow is undoubtedly much more numerous than it was before the
arrival of settlers. Crows may gather in roosts of over half a million
birds and are so abundant that even an ardent defender of birds might
not deny that they are destructive to crops and should be controlled,
although they consume enormous amounts of grasshoppers, cutworms, and
other harmful insects. Crows make interesting pets if obtained while quite
young; some learn to mimic the human voice. They often carry off and hide
bright objects.
