Summary:
Unlike mammals, birds have no external ears. The outer ears have an important function: they help the animal identify sounds coming from different elevations. But birds are also able to perceive whether the source of a sound is above them, below them, or at the same level. Now a research team has discovered that birds are able to localize these sounds by utilizing their entire head.
