猛禽视觉研究新进展

 鸟类高度依赖其对视觉环境的评估结果。概述了以猛禽为代表的鸟类视觉生理系统和视觉信息感知系统特性的研究现状，对比了不同种类猛禽视觉系统的特性与优缺点。首先描述了包括眼外周结构、眼球壁和眼内的折光系统在内的解剖学结构，分析了猛禽眼和其他动物的眼之间的区别；然后介绍了猛禽视觉信息的传导通路和中枢；最后阐明了猛禽与其他动物不同的颜色感知特性、双中央凹特性以及猛禽视觉敏锐度特性，并概述了当前模拟猛禽视觉特性的研究方法以及关键问题，探讨了其未来的发展趋势。

New progress of the visual system in birds of prey

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.
