The Galapagos Hawk is endemic to the Galapagos and is similar to the red tailed hook that can be found in North America. The hawks found in Española Island are the biggest in the archipelago averaging 1,140gr, and the smallest are found in Marchena Island weighing about 844gr. Males are smaller and lighter than females.
This bird has developed an interesting breeding method. As many as 3 hawks would reproduce with the same female and all would assist the nursing by bringing food. They lay 3 to 6 eggs, and depending on the food availability, all will survive.
They feed on dead animals and also hunt insects, mammals, reptiles and other birds. However, there are few birds that are fearless of the hawks, such as the mockingbird that would even fight them to protect their nest. They can hunt in groups of 3, one being the leader, displaying strategic chasing or mocking when needed.
There are supposed to be about 300 individuals in the archipelago, so they are highly endangered, mainly because of introduced species. They are currently extinct in Baltra, Daphne, Floreana, San Cristobal, and Seymour islands.
