Video proving that owls fly in complete silence [View all]
When one thinks of birds flying, the two things that immediately come to mind are the sight of their wings flapping and the sound of air being moved around them. So, we tend to assume that all birds get somewhat noisy when they fly. However, there is one bird that stands as an exception to this by flying very silently. Owls, small or large, somehow manage to fly around without making any sound from their wings.
A team from BBC Earth wanted to test out the actual difference in the sounds made by owls and other birds while flying in order to understand just how silent the nocturnal raptors really are. The team brings in a pigeon, a peregrine falcon and a barn owl to fly from one point to the other, with mics lined up alongside their flight path to record the sound made by their wings. They record all three of the birds, with the pigeon making the most noise and the owl making almost none at all.
