Little bird nesting in yellow letterbox (5)
I believe the answer is:
owlet
'little bird' is the definition.
(I've seen this before)
'in yellow letterbox' is the wordplay.
'in' says the answer is hidden in the clue.
'OWLET' is hidden in the letters of 'yellow letterbox'.
'nesting' acts as a link.
I am not very happy about this link. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for owlet that I've seen before include "Nestling" , "Baby bird of prey" , "Junior member of parliament" , "Little nocturnal bird" , "Wise baby bird?" .)
