The Harris’s Hawk is a medium-sized bird of prey that ranges from south United States all the way to Brazil and Argentina. Adults are very dark with chestnut on the shoulders, wings and legs, as well as some patches on the head. The juveniles are lighter in coloration overall, with wings underside being buff to white and having dark streaking. Their eyes are very big and situated all the way forward, allowing them for good tridimensional vision and distance judging, essential for spotting and catching prey. Due to their intelligence, they are sought after for falconry, particularly in some parts of Europe. In their natural environment, they are known for cooperating and hunting in groups up to seven individuals, with the mature female being the highest ranked individual.
