Overlaps in habitat with American Crow, but more likely to be near water, especially along coast, where it forages on beaches, marshes, and estuaries. Inland from coast, usually follows the drainages of large rivers, although it may feed in woods or fiel
ds a few miles from the water.
Nest: Site is in upright fork of tree or shrub. May be very low in coastal growth of pines, cedars, or quite high in deciduous trees in inland swamps; nest height may be 5-
70′ above ground or even higher. Nest (probably built by both sexes) is a bulky platform of sticks and strips of bark, lined with softer materials such as grass, rootlets, hair, feathers, paper, pine needles, even manure.
Eggs: 4-5. Dull blue-green to gray-green, blotched with brown and gray. Incubation is by female, possibly assisted by male, about 16-18 days.
Young: Both parents probably bring food to nestlings. Age when young leave the nest not well known, probably 3-4 weeks.
Usually forages in flocks. Does most foraging by walking, especially on shores or in very shallow water, also in fields; sometimes forages in trees. May carry mollusks up into the air, then drop them on rocks to break the shells. In colonies of herons an
d other waterbirds, if adults are frightened from their nests, Fish Crows may destroy many eggs.
