Up to five or six birds have been observed raising young together, usually the parents and their previous offspring. Although they do most of the incubation alone, females usually have help raising the young from at least one male. Females incubate up to five eggs for 33 to 36 days. They use sticks to build compact nests in trees, bushes, cacti, and even human-made structures. It is believed that this behavior also strengthens social bonds.įemales often mate with more than one male. This allows more birds to keep watch for predators, even though branch space available for perching may be limited. Unlike wolves, they engage in a unique behavior called “stacking,” in which one bird will sit on a branch, and up to three additional birds will sit atop its back. In some regions they hunt cooperatively and once they catch prey, will take turns consuming it. Harris hawks are known as “wolves of the sky” for their social behavior, including aerial displays in which males make dramatic vertical dives to impress females. They weigh between one and a half and two and a half pounds. Their wingspan ranges from three and a half to four feet, much wider than their body length of 18 to 22 inches. Like other hawks, they have long, sharp talons on their feet. The dark chestnut feathers on their backs and chests are highlighted by bright, rusty-colored feathers on their thighs and patches on their wings. This striking species is distinguished by a broad, wide stripe of dark feathers across the end of its tail, which contrasts with the bright white feathers at the base. Other examples of raptors you can see at the Zoo are owls, eagles, and vultures. Likewise, their feet feature talons which are uniquely used for catching prey, in addition to more common uses such as defense, perching, and transporting materials. There is some variation in the size and shape of their beaks, but they are all curved and sharp. Raptors have keen vision and therefore have large eyes compared to their bodies. Hawks belong to a group of birds known as raptors, which are loosely defined by a few physical characteristics. In some regions where they live this species is social, but in most regions, they are observed alone or with just one other hawk. ![]() ![]() In the case of Harris hawks, birds of a feather don’t only flock together – they hunt and nest together, too.
