虽然紫外线视觉在20世纪70年代初首次在鸟类中得到证实，但其功能仍然未知。在这里，我们回顾了鸟类紫外线视觉的证据，讨论了紫外线的特殊性质，详细阐述了鸟类紫外线视觉功能的假设，并讨论了它们的可解释性。主要的假设是，紫外线视觉功能：（i）在方向，（ii）在觅食和（iii）在信号。第一种观点得到了信鸽研究的支持，但得出定向是紫外线在所有鸟类中的主要功能的结论是不明智的。测试信号假说尤其重要，因为鸟类的羽毛经常反射紫外线，而性选择理论的测试几乎总是假设鸟类像人类一样感知羽毛的“颜色”。这种假设不太可能是正确的，因为与人类不同，鸟类在紫外线下看到，至少有四种锥细胞，并且有一个油滴系统，可以过滤进入单个锥细胞的光。
Although UV vision was first demonstrated in birds in the early 1970s, its function is still unknown. Here we review the evidence for UV vision in birds, discuss the special properties of UV light, lay out in detail hypotheses for the function of UV vision in birds and discuss their plausibility. The main hypotheses are that UV vision functions: (i) in orientation, (ii) in foraging and (iii) in signalling. The first receives support from studies of homing pigeons, but it would be unwise to conclude that orientation is UV's primary function in all birds. It is especially important to test the signalling hypothesis because bird plumage often reflects UV and tests of theories of sexual selection have virtually always assumed that birds perceive plumage ''colours'' as humans do. A priori this assumption is unlikely to be correct, for unlike humans, birds see in the UV, have at least four types of cones and have a system of oil droplets which filters light entering individual cones.
