Harris hawk perched

The Harris's hawk (Parabuteo unicinctus) is a sociable bird of prey native to the Americas, known for hunting in groups and widely used in falconry.

About this subject

The Harris's hawk (Parabuteo unicinctus), also called the bay-winged hawk or Harris hawk, ranges from the southwestern United States to Chile and Argentina. Its plumage is mostly dark brown with chestnut shoulders and thighs, and a white band at the tail tip. It measures 45 to 60 centimeters in length with a wingspan of 100 to 120 centimeters. Females are larger than males, weighing up to 1.2 kilograms.

Unlike most solitary raptors, the Harris's hawk exhibits a rare social behavior: it hunts in cooperative groups of two to six individuals. This pack hunting allows them to take down larger and faster prey, such as rabbits and birds. The strategy involves coordinated pursuit and relay, showcasing advanced intelligence and communication. They live in stable family units where offspring help raise subsequent broods.

In falconry, the Harris's hawk is highly prized for its docile temperament, trainability, and ability to learn complex commands. Unlike falcons that soar high, it attacks from low perches, making it easier to handle. It is commonly featured in educational demonstrations and urban pest control programs, such as bird abatement at airports and farms.

The species is not globally threatened (IUCN: Least Concern), but local populations may decline due to habitat loss. The name "Harris" honors Edward Harris, a friend of naturalist John James Audubon. In the United States, it is the state raptor of New Mexico. Its adaptability to diverse environments, from deserts to tropical forests, explains its evolutionary success.
