Morphology

covert = cover (transparent) = cover + t

The ornithological term for a feather that 'covers' other feathers is a direct semantic extension of 'cover'.

Etymology

Covert for a bird feather comes from the word cover, because these small feathers 'cover' the bases of the big wing and tail feathers. So, the name coverts fits — they are little 'covers' that help smooth the bird's flight.
