Auriculars or ear coverts vary greatly among bird species.
In the case of doves, they are designed to cut down wind noise while flying.
According to the Sibley Guide to Birds, auriculars are a
“complex set of feathers that channel sound into the ear.
Feathers at the rear border are short, sturdy, and densely
colored.  Feathers over the ear opening are lacy and unpatterned.”
