The most extreme known species of accipitrid in terms of sociality is the Harris's hawks (Parabuteo unicinctus), which up to seven fully-grown birds may hunt, nest and brood cooperatively, with the extra birds typically being prior years' offspring of the breeding pair.
Other water birds recorded as prey include cormorants (up to 8.6% of the recorded prey in Santa Rosa and Santa Cruz Islands), auks, grebes and loons. [10] [30] Other raptorial birds can sometimes become semi-regular prey, such as various hawks which are recorded largely in North America at locations such as Oregon (8.8% of prey remains) and ...
The large birds also regularly lock feet with each other and fall some distance through the sky with each other. [14] In Europe, the breeding pairs of bearded vultures are estimated to be 120. [ 41 ] The mean productivity of the bearded vulture is 0.43±0.28 fledgings per breeding pair per year and the breeding success averaged 0.56±0.30 ...
The American goshawk (Astur atricapillus) is a species of raptor in the family Accipitridae. It was first described by Alexander Wilson in 1812. The American goshawk was previously considered conspecific with the Eurasian goshawk but was assigned to a separate species in 2023 based on differences in morphology, vocalizations, and genetic divergence.

The black kite was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux in 1770. [3] The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text.
