I'm a little stuck... Click here to teach me more about this clue!

'bird' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'otter somehow found in hollow dell' is the wordplay.
'somehow' is an anagram indicator.
'found in' indicates putting letters inside.
'hollow' means to remove the middle letters (the word is hollowed out).
'dell' with its centre removed is 'dl'.
'otter' anagrammed gives 'ottre'.
'ottre' inserted into 'dl' is 'DOTTREL'.
