Trek less to find these small falcons (8)
I believe the answer is:
kestrels
'these small falcons' is the definition.
(I've seen this in another clue)
'trek less to find' is the wordplay.
'to find' indicates an anagram.
'trek'+'less'='trekless'
'trekless' is an anagram of 'KESTRELS'.
(Other definitions for kestrels that I've seen before include "Small falcons" , "Birds of prey" , "Elk rests awkwardly on the birds" .)
