The American crow belongs to Corvidae family.

They have long legs, thick neck with a sturdy bill. Whilst in the air, their wings are rounded with the wing tip spread, their tail are short. Their whole body is black.

They are social, curious and playful birds. They are aggressive to other larger birds. There can be up to two million birds in a flock. In the winter they congregate and form roosts, the majority of the birds will come back to the same area every year. 

They live in fields and forests. They have had to adapt to live in urban areas, as their habitat is being replaced by buildings and humans. They look through bins to find any food. 

The crows are able to breed at two years of age. The majority of populations the young aid the parents in the upbringing on the babies.

The male and female construct the nest, it is built from sticks, weeds, hair and leaves. The females lay three to nine eggs at a time, the eggs are in incubation for forty days and once hatched in the nest for a further forty days. The chicks do not have any hair when hatched.

The crows are foragers and scavengers, the feed on road kill, small birds, fruit, seeds, nuts, insects and fish. They work together in problem solving, scaring away predators and to find food.
