Flier organising a cordon (6)
I believe the answer is:
condor
'flier' is the definition.
(condor is a kind of birdanimal)
'organising a cordon' is the wordplay.
'organising' indicates anagramming the letters.
'cordon' anagrammed gives 'CONDOR'.
(Other definitions for condor that I've seen before include "Andean bird" , "South American vulture" , "Large American vulture" , "Large bird of prey" , "Large bird of the Andes (national symbol of Peru)" .)
