Bird caught on Cornish river to the west (6)
I believe the answer is:
falcon
'bird' is the definition.
(falcon is a kind of bird)
'caught on cornish river to the west' is the wordplay.
I cannot quite understand how this works, but
'caught' could be 'c' (cricket abbreviation) and 'c' is present in the answer.
'on' is within the answer.
'river' could be 'fal' (Cornish river) and 'fal' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for falcon that I've seen before include "Hunting bird, may be trained" , "Diving bird of prey" , "Hunter winged" , "A hunting bird, may be peregine" , "Hunting bird like peregrine or merlin" .)
