The fishing crow ( Corvus ossifragus ) is an American type of crow that is found mainly in wetlands.

description

The fish crow is outwardly very similar to the American crow , but it is smaller with 36–41 cm in length and has silky plumage. The plumage is black everywhere, on the top it shimmers blue-green, while it has a more greenish shimmer underneath. The eyes are colored dark brown. The two species can often only be distinguished by direct comparison or by reputation.

distribution and habitat

Distribution area of ​​the crow

The species lives on the east coast of the United States from Rhode Island south to Key West and on the north coast of the Gulf of Mexico . It is also widespread inland along river systems.

The habitat is largely limited to wetlands and coastal or bank strips along the coast and the rivers and the directly adjacent areas.

behavior

nutrition

Food is sought on land and in shallow water. The crow flies over areas of shallow water and grabs food out of the water with his feet. It will eat small crustaceans and other invertebrates , stranded fish , eggs and nestlings of other birds, small reptiles , fruits and seeds and human waste. Live fish are also caught when circumstances permit.

Reproduction

The nest is usually established in tall trees in small, loose colonies . The female lays 4–5 blue-green, olive-colored spotted eggs .

Danger

The species appears to be slightly more resistant to the West Nile virus than the American crow. Survival rates as high as 45% have been reported, while those in the American crow are close to zero.

In the Red List of Threatened Species of IUCN , the fish crow will be deemed not at risk.
