The visual ability of birds of prey is legendary, and the keenness of their eyesight is due to a variety of factors. Raptors have large eyes for their size, 1.4 times greater than the average for birds of the same weight, [14] and the eye is tube-shaped to produce a larger retinal image.
Birds have color vision, but unlike us, they can see in ultraviolet, which opens up a whole world of colors that we’ll never know. They also have impressive distance vision, the ability to adjust for light refraction through water, and incredibly wide fields of view.

19 de jul. de 2012 · Birds and UV Light: The Eyes Have It. How do birds detect ultraviolet (UV) light? To answer this question you must understand avian eye structure. The human retina has three kinds of cone cells (receptors used for color vision): red, green and blue. By contrast, birds active during the day have four kinds, including one that’s ...
1 de jun. de 2016 · Bird eyes, like ours, function by admitting light through the transparent cornea, lens, and vitreous body to stimulate photoreceptors on the retina at the back of the eye. Each retina has at least one fovea, a densely packed concentration of photoreceptors that’s responsible for sharp central vision.
Color Vision and UV Perception. Most birds are diurnal, with densely packed cones on the retina for excellent color vision. Remarkably, many birds are known to have tetrachromatic vision, which means they have four types of color-sensitive cones and can detect light in the ultraviolet (UV) spectrum. Ultra-violet vision is thought to help them ...
4 de oct. de 2023 · Binocular vision: many birds have significant binocular vision due to the arrangement of their eyes on the front of their heads. This allows them to partially overlap the images they see with each eye and perceive depth and distances more accurately.
