Mimus polyglottos - Northern mockingbirds usually pair for life. The male will stake out a territory and begin courtship displays when the breeding season starts in spring or late summer. When a female has been attracted, the male will build the nest while the female perches nearby. The female will deposit 3 to 5 eggs; the incubation period lasts from 11 to 14 days. The chicks fledge after another 10 to 15 days. Both parents will provide for their hatchlings and are known for their aggressive behavior in protecting their chicks and nest.
