What is the life cycle of crows?

Crows have a life cycle that begins with the mating season, typically in late winter or early spring, when they form monogamous pairs. After mating, the female builds a nest, usually in trees or shrubs, where she lays 3 to 7 eggs. The eggs hatch after about 18 days, and both parents care for the chicks, which fledge around 4 to 5 weeks later. Crows can live for several years, with some reaching up to 20 years in the wild.
