At the start of spring, the male sings loudly to attract the attention of the female. During courtship, both partners perch and sing. Once the pair is formed, the male and female Robins become aggressive to protect their nesting territory and keep a check that they do not lose their partner to another bird. The male fetches food for his partner to make sure that she gains enough weight to lay eggs and incubate them. Robins generally raise two broods a year. Each clutch usually contains about five to six eggs. The female does the incubation duties, while her partner gets food for her and guards the nesting territory. The partners involve equally in feeding and protecting the young ones after the eggs hatch.
