'cuckoo finch owls' is the definition.
The answer and definition are not the same part of speech.

'cuckoo finch owls' is the wordplay.
'cuckoo' indicates an anagram (I've seen this in other clues).
'finch'+'owls'='finchowls'
'finchowls' anagrammed gives 'CLOWNFISH'.

Can you help me to learn more?
