ABSTRACT
The article discusses how birds use ultraviolet (UV) light. Birds are considered to be tetrachromatic, which means that they have a fourth kind of retinal cone for perceiving wavelengths in the UV spectrum. Studies have demonstrated that UV light has been used by some bird species for hunting prey. It has also been discovered that birds utilize UV light for communication and signaling.
