Hood could be put on this bird (5)
I believe the answer is:
robin
This could be a double definition.
'hood' is the first definition.
(I've seen this in another clue)
'be put on this bird' is the second definition.
'robin' can be an answer for 'bird' (robin is a kind of bird). I'm not certain of the remainder of the definition.
'could' is the link.
Can you help me to learn more?
(Other definitions for robin that I've seen before include "good fellow in the D [DREAM]" , "Small songbird" , "Bird - boy's name" , "Hood, possibly" , "Red and brown songbird" .)
