John James Audubon gave this bird its English name in honor of his ornithological companion, financial supporter, and friend Edward Harris.

Harris's hawks' social nature has been attributed to ...

African harrier-hawks have been identified to employ four different hunting strategies namely: low soaring, high soaring, perch hunting and, canopy and ground foraging.

The men drive them away with sticks, while the hawks pursue closely, and the small birds in their flight fall into the clutches of the men.
When hunting cooperation is across two or more species, the broader term cooperative hunting is commonly used. A well known pack hunter is the gray wolf; humans too can be considered pack hunters. Other pack hunting mammals include chimpanzees, dolphins, such as orcas, lions, dwarf and banded mongooses, and spotted hyenas.
As climate change fuels stronger storms, those can disrupt migration patterns, causing birds to stay in certain areas for longer, move later in the season, or risk mortality moving during a hurricane.
The wedge-tailed eagle has a unique moult process in that they moult almost continuously and very slowly, and it might take three or more years for an eagle of the species to complete a moult. Moults are arrested only at times of famine, and happen gradually, so that they do not impede the bird's flight or hunting capacities. [8] [22]
