Visual sensitivity in ultraviolet (UV) light is widespread in the animal kingdom and occurs in all major taxonomic groups, including birds, which possess UV-sensitive photoreceptors and thus perceive UV light and use it in food selection, mate choice, offspring care and egg discrimination. However, no studies have been conducted to elucidate whether birds (aerial predators) could detect nests by UV light reflectance of eggs. In the present study, we performed artificial tree nest experiments in which pairs of pigeon eggs were treated with either a UV-blocker or a control substance before being exposed to nest predators in a tropical forest. The results showed that nest predation increased with duration of exposure, and that blocking UV reflectance of eggs could significantly reduce nest predation on tree nests. This provides experimental evidence for nest predation risk being linked to UV reflectance, and implies that aerial nest predators may detect nests by UV reflectance of eggs.
