Answer:-
______________
The external part of the ear is called the "pinna", and only mammals have it. In fact not even all mammals: the most "primitive", the monotremes (egg-laying mammals -- platypus and echidna) don't have ears with a pinna.
However, without those outer-ears, it should be near-impossible for birds to tell which direction a sound is coming from. ... When they hear a sound, they tilt their head in the general direction their specialized eardrums indicate, and then let their sharp vision take over, sweeping an area for the source.
