This species occurs in relatively stable groups. A dominance hierarchy occurs in Harris's hawks, wherein the mature female is the dominant bird, followed by the adult male and then the young of previous years. Groups typically include from two to seven birds. Not only do birds cooperate in hunting, but they also assist in the nesting process. [24]
Black-headed gulls, bar-tailed godwits and sanderlings foraging on a beach. A mixed-species feeding flock, also termed a mixed-species foraging flock, mixed hunting party or informally bird wave, is a flock of usually insectivorous birds of different species that join each other and move together while foraging. [1]
Bird species living in a flock may capture prey, likely injured, from an unsuccessful bird within its flock. [2] This behavior is known as the beater effect and is one of the benefits of birds foraging in a flock with other birds. [2] It can be seen that birds in a flock may perform the information-sharing model. [2]
When the hunting finishes, the hunters give a portion of all that is caught to the hawks. [44] He also wrote that in the city of Cedripolis (Κεδρίπολις), men and hawks jointly hunt small birds. 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.
Birds make use of a variety of approaches to improve the efficiency of their foraging. These include foraging in flocks which provides many eyes to seek patches rich in food while also reducing the risk of predation by increasing the efficiency of detecting predators, increasing time spent on handling food, and by reducing individual risk .
Although the term "bird of prey" could theoretically be taken to include all birds that actively hunt and eat other animals, [4] ornithologists typically use the narrower definition followed in this page, [5] excluding many piscivorous predators such as storks, cranes, herons, gulls, skuas, penguins, and kingfishers, as well as many primarily ...

Measurements of bird flocking have been made [3] using high-speed cameras, and a computer analysis has been made to test the simple rules of flocking mentioned below. It is found that they generally hold true in the case of bird flocking, but the long range attraction rule (cohesion) applies to the nearest 5–10 neighbors of the flocking bird and is independent of the distance of these ...
