Hood for a bird (5)
I believe the answer is:
robin
I believe this is a double definition.
'hood' is the first definition.
(Robin Hood)
'bird' is the second definition.
(robin is a kind of bird)
'for a' acts as a link.
(Other definitions for robin that I've seen before include "So-called outlaw" , "Traditional Christmas card bird" , "Bird on many cards" , "Red-breasted Christmas card bird" , "Bird; Batman's aide" .)
