The distribution of UV perception among birds is discussed. UV-sensitive eyes have UV-transparent occular media and cone types maximally sensitive around 360 or 420 nm. Since most birds have three more cone types with absorption maxima in the ranges 450-480 nm, 510-540 nm, and 565 - 620 nm, tetrachromatic color vision must be presumed. Some aspects of tetrachromatic colour vision are discussed. Fruits with a wax layer reflect UV, as do some skin and horn parts of blue and yellow coloration. Among red, yellow green, blue, and violet feathers there are many which reflect in the visible range as well as in the UV range. Black feathers may have UV reflection; white feathers may lack it. The appearance of feathers for UV-perceptive birds is discussed with respect to UV reflectance.
