Fish Crow - Corvus ossifragus

The Fish Crow is very similar to the more widespread American Crow. However, while the American Crow is found throughout much of North America, the Fish Crow's range is restricted to the southeastern United States, where they are most often found along the coast or near large river systems. They can be extremely difficult to differentiate from the American Crow, although they are slightly smaller, and have other minor structural differences. The safest way to tell the two species apart is by voice.

Habitat

Found in a variety of habitats, but tends to be found around water. They are most often found along the coast and surrounding habitats, but can also be found inland near large river systems.

Diet

Omnivorous. Diet depends upon location and seasonality, but may include insects, crustaceans, mollusks, bird eggs, reptile eggs, small vertebrates, carrion, refuse, fruits, nuts, and berries.

Behavior

Foraging technique depends on the food item, but they most often foraging by walking along the ground.

Nesting

The nest of a Fish Crow is a large platform of sticks and pieces of bark, lined with softer materials that may include grasses, weed stems, rootlets, feathers, pine needles, or even refuse. The female lays 4 or 5 eggs, and she likely does most of the incubation. When the eggs hatch, both parents help feed the young and tend to them.

Song

Most often gives a simple, nasal caw call. Also has other hoarse croaking and rattling calls.

Migration

Considered a permanent resident throughout its normal range. Birds found inland, however, may move more towards the coast for the winter.
