Birds rely most heavily on their ability to assess their visual environment. The current research situation of vision of birds of prey is introduced and the characteristics of the photographic systems in different families of birds of prey are compared. First, the anatomy structure of the periphery is described, including the eyeball and lens, by which the basic differences between birds of prey and other avian are analyzed. Then the visual information processing pathway and the optic center are introduced and the special color perception, double fovea and unusual visual acuity of the birds of prey are elaborated. Finally, the current research methods, existing problems and future trends are discussed.
