The nest is made of twigs, branches and bark and lined with soft materials like moss, grass, feathers, and leaves. Both the male and female construct the nest. The female lays from four to six eggs that are bluish or greyish green and have brown and grey markings. After raising their young, crows gather in groups that roost together each night. In the day they divide into small groups and go searching for food.
Crows are omnivores and eat almost anything they can find.
They scavenge for food in garbage dumps and along roadsides where animals have been killed by cars. Crows eat the eggs and young of other birds and this makes them very unpopular with bird watchers. They also eat seeds, berries and especially corn. Some studies have shown that nearly two-thirds of their diet in the summer are insects like beetles, grubs, bees, grasshoppers, termites, and ants. This means they control insects that harm farmers' crops.
