May be sent home (4)
I believe the answer is:
nest
'home' is the definition.
(a bird's home)
'may be sent' is the wordplay.
'may' indicates an anagram (I've seen 'might' mean this (I've seen this in other clues)).
'sent' is an anagram of 'NEST'.
(Other definitions for nest that I've seen before include "Avian structure" , "home for 22d [VIPERS]" , "Place to lay eggs" , "Ingredient of Chinese soup" , "Home of twigs, perhaps" .)
