Bird protected by her monkey (3)
I believe the answer is:
owl
'bird' is the definition.
(owl is a kind of bird)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for owl that I've seen before include "Member of Parliament" , "Traditionally wise bird" , "Night hunter" , "Athena's bird" , "Hooting bird" .)
