Do Hawks Mate for Life?
One type of hawk, the red-tailed hawk of the Western Hemisphere, will mate for life if conditions allow it. All of the other raptors named hawks of the family Accipitridae are likely to be monogamous until the time that the babies are grown and ready to leave the nest.
Hawk Courtship
Courtship for many hawks is a spectacular, semi-choreographed affair that evolved over many millennia. The red-tailed version is most commonly seen in North America, Central America, and even the Caribbean (Buteo jamaicensis). After a mating pair make graceful aerial circles at high altitude, the male red-tailed hawk will plummet toward the earth and back up to where the female is still circling high. The two will consummate the act a little later in the same way while falling toward the ground like skydivers with built-in parachutes.
These same hawks are the only species known to mate regularly for life. Both will incubate their seasonal eggs and take turns feeding them until they’re ready to fly off a month or two later.
Other Species that Mate for Life
According to a Stanford University research paper, about 90 percent of bird species are monogamous, though only certain species will be so for life. Some other birds that are in it for the long haul: species of the albatross, eagle, penguin, petrel, swan, goose, and owl.
