Rents out birds (5)
I believe the answer is:
terns
'birds' is the definition.
(tern is a kind of bird)
'rents out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'rents' anagrammed gives 'TERNS'.
(Other definitions for terns that I've seen before include "Sea bird with long forked tail" , "Rents out these birds" , "Sea birds with long forked tails" , "Seabirds" , "Aquatic birds" .)
