Warder released female bird (3-5)
I believe the answer is:
bee-eater
'bird' is the definition.
(bee eater is a kind of bird)
'warder released female' is the wordplay.
'warder' becomes 'beefeater' (Beefeater can informally mean a Yeomen Warder).
'released' suggests deleting specific letters (deleted letters are released or sent out).
'female' becomes 'f' (common abbreviation).
'beefeater' with 'f' taken away is 'BEE-EATER'.
(Other definitions for bee-eater that I've seen before include "Insectivorous bird" , "Insect-consuming bird" , "Bright bird" , "Bright avian insectivore" .)
