Bird from Maine, a nocturnal predator shrouded in dark (10)
I believe the answer is:
meadowlark
'bird' is the definition.
(meadowlark is a kind of bird)
'maine a nocturnal predator shrouded in dark' is the wordplay.
'maine' becomes 'me' (abbreviation).
'nocturnal predator' becomes 'owl' (I've seen this in another clue).
'shrouded in' indicates putting letters inside.
'owl' inserted inside 'dark' is 'dowlark'.
'me'+'a'+'dowlark'='MEADOWLARK'
'from' is the link.
(Other definitions for meadowlark that I've seen before include "Bird" , "Songbird" .)
