The Galapagos hawk is closely related to North America’s red-backed and white-tailed hawks, and is endemic to the Galapagos Islands. It is one of the world’s rarest raptors, with an estimated population of just 150 breeding pairs. Galapagos hawks mainly feed on invertebrates such as giant centipedes and locusts, but also occasionally predate snakes, rodents, lizards, young iguanas, turtle hatchlings and other birds. They are also some of the major scavengers in Galapagos, feeding off carcasses using their strong beaks.The Galapagos hawk has quite a unique breeding system known as cooperative polyandry. Although the males are entirely monogamous, the females can mate with up to seven males throughout the nesting period. These males then help to raise the chicks (usually three in a clutch) by taking turns incubating eggs and feeding the hatchlings.
