A group of crows is often referred to as a "floater flock", which is a social group that forms during breeding season and may contain up to 50 birds. Crows also establish groups called winter roosts in the autumn that build in numbers until mid-winter and often have tens of thousands of birds.
Crows are social birds that will stay close to the habitat or area in which they were born in order to defend the territory and assist the mother crows in raising new young. Being omnivores, crows will eat almost anything, including rotting animal flesh. Crows are preyed on by other birds and animals such as, red-tailed hawks, great horned owls, domestic cats, raccoon and snakes.
