Parrots, in addition to bright colors, use fluorescence to attract the couple. Birds are able to see fluorescence with daylight. According to British and Australian researchers, feather fluorescence has a sexual function.

For the research were covered the feathers of some little ones with sun cream and others with gelatin. In all cases, the little dogs preferred that members who did not have sun cream pass through the gorges. Biologically fluorescent color production is expensive, so researchers consider it logical to be a strategy to capture the best pair.
