Often the family group sticks together until the following spring. Crows are both predators and prey. As predators, they rob nests of songbirds and waterfowl, killing and eating newly hatched young, or cracking eggs. As prey, young crows and unhatched crow eggs are eaten by raccoons, opossums and tree-climbing snakes. Hawks and owls kill fledgling and adult crows.
Crows are especially vulnerable to night attacks by great horned owl.
They also mob hawks. In turn, crows are mobbed by smaller birds, especially kingbirds and red-wing blackbirds. Crows are curious. Shiny objects fascinate them, and they have been known to fly off with bits of glass, rings, keys, etc. Crows exhibit their intelligence by imitating a large number of sounds, including whistles, cats, machines and the human voice.
