Red-tailed hawks perform spectacular courtship flights involving diving, "barrel rolls", and shrill screams. They are monogamous and pairs will usually mate until the death of one partner.
Red-tailed hawks have large nests which can be found high above the ground such as in tall trees or cacti, on cliffs, or on man-made structures. Both the male and female build the nest using sticks, bark, twigs, and other fine material.
Females lay 1-5 eggs each year. Males and females will incubate the eggs for 4-5 weeks and take part in caring for the young until they leave the nest in about 6 weeks. The young become sexually mature when they are about 1-2 years of age.
