Researchers have finally revealed what gave the extinct Pink-headed Duck its unique-colored plumage.
Blue jays are adorned with striking blue feathers that never fade. It turns out birds are able avoid going gray – unlike humans – because their feathers contain sophisticated nanostructures that reflect light better than pigmentation.
A 'supergene' that affects a male ruff bird's plumage ultimately determines its mating strategy.
Heavy metals such as mercury, chrome and copper alter the brightness of some birds' feathers, making them seem less attractive to females.
We all know that it's hard to keep up appearances when you're constantly on the go. That's why the fashion police will probably give some female warblers a free pass, even after researchers found that they boast drabber feather when their migration routes are particularly long.
