What bird shakes wings? (4)
I believe the answer is:
hair
'bird shakes wings?' is the definition.
The definition and answer can be both animals as well as being singular nouns.
Maybe there's a link between them I don't understand?
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for hair that I've seen before include "Nineteen sixties musical; filament" , "Thread-like structure(s)" , "The American Tribal Love-Rock Musical (1967)" , "Fur, say" , "A very small quantity" .)
