Creature flying to cave (6)
I believe the answer is:
avocet
'creature' is the definition.
The definition and answer can be both animals as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'flying to cave' is the wordplay.
'flying' indicates anagramming the letters.
'to'+'cave'='tocave'
'tocave' anagrammed gives 'AVOCET'.
Can you help me to learn more?
(Other definitions for avocet that I've seen before include "Wading bird with curved bill" , "Wading bird with upturned bill" , "RSPB emblem" , "Shorebird - octave (anag)" , "Long-legged shorebird with upward-curving bill" .)
