The Eurasian woodcock’s white tail feathers reflect up to 55% of light –30% more than those of any other bird
The Eurasian woodcock’s white tail feathers reflect nearly a third more light than any other feather, research led by Imperial College London has found.
Scolopax rusticola are primarily brown, but they do have patches of white feathers beneath their tails that are on display when their tail is raised and during courtship display flights.
