Raptors have always fascinated mankind, owls for their highly sensitive vision, and eagles for their high visual acuity. We summarize what is presently known about the eyes as well as the visual abilities of these birds, and point out knowledge gaps. We discuss visual fields, eye movements, accommodation, ocular media transmittance, spectral sensitivity, retinal anatomy and what is known about visual pathways. The specific adaptations of owls to dim-light vision include large corneal diameters compared to axial (and focal) length, a rod-dominated retina and low spatial and temporal resolution of vision. Adaptations of diurnal raptors to high acuity vision in bright light include rod- and double cone-free foveae, high cone and retinal ganglion cell densities and high temporal resolution. We point out that more studies, preferably using behavioural and non-invasive methods, are desirable.

白天和夜间猛禽的视觉适应。

猛禽向来着迷人类,猫头鹰以高度敏感的视力着迷,鹰以高度的视敏度着迷。我们总结了目前关于这些鸟的眼睛以及视觉能力的已知知识,并指出了知识差距。我们讨论视野,眼球运动,适应性,眼介质透射率,光谱敏感性,视网膜解剖以及关于视觉通路的知识。猫头鹰对昏暗视觉的特殊适应包括与轴向(和焦距)长度相比,角膜直径大,视杆占主导的视网膜以及视觉的时空分辨率低。日头猛禽对强视力的适应在明亮的光线下包括无杆和双锥无中心凹,高锥和视网膜神经节细胞密度和高时间分辨率。我们指出,更多的研究,
