Flier many recollected (4)
I believe the answer is:
myna
'flier' is the definition.
(myna is a kind of birdanimal)
'many recollected' is the wordplay.
'recollected' indicates anagramming the letters (letters recollected and rearranged).
'many' anagrammed gives 'MYNA'.
(Other definitions for myna that I've seen before include "Asiatic bird imitating human speech" , "Mimicking bird" , "Asian bird" , "Speech-mimicking bird" , "Talkative bird" .)
