- Cereals
- Nestlings of other birds
- Insects
- Mollusks
- Earthworms
- Nuts
- Fruits
- Mice
- Eggs

Crows are highly social birds who create big knit-families, much like some social mammals. These social groups include all species of birds, including males, females, youngsters, and infants. Crow flocks can range in size from a few hundred to thousands of individuals. All of the members participate in hunting, gathering food, foraging, nurturing the young, and protecting their own territory.
In a large crow colony, each of the mating couples constructs their own nest from sticks and twigs. The majority of the nests are constructed on the uppermost branches of the trees. It has been observed that a female bird lays five to seven greenish-colored eggs with dark blue sparkles on them, which are then incubated.
The young crows spend the first five to six years of their lives with their parents before leaving the nest when they find a suitable spouse. Crows that dwell in northern locations congregate in great numbers as the chilly season approaches. These big groups provide protection from the cold weather as well as against predators such as owls. This family-oriented way of life, which these birds have chosen, is a key aspect in the protection and survival of these birds in harsh environments.
