In flight, it is distinguished from other blackbirds by its frequent, steady wing beat with little or no gliding. Crows are one of the most intelligent and wary birds, have good memories, are good at solving puzzles and are quick to learn to associate various noises and symbols with food. They eat almost anything. The remainder of the crow's diet consists of vegetable and plant matter, and even garbage. Patterns of Behavior Crows have two broad patterns of behavior.
Crows pair off in early spring, building a nest of twigs, sticks and stems.
The nest may be built on the ground, in areas where there are few trees, or as high as 60 feet above ground in oaks or pines. Young leave the nest in about five weeks, forage with their parents throughout summer and join larger and larger groups as fall approaches. Huge groups often migrate in late fall or winter, roosting together at night and flying as far as 50 miles each day to feed. Small potato plants are pulled up, and angled holes are eaten out of attached seed pieces. Crows damage seedling corn plants by pulling the sprouts and consuming the kernels.
