'could one' is the definition.
I can't tell whether this definition defines the answer.

'fly to peru?' is the wordplay.
'fly' indicates anagramming the letters (I've seen 'flying' mean this (letters fly around into new positions)).
'to'+'peru'='toperu'
'toperu' with letters rearranged gives 'POUTER'.

Can you help me to learn more?

(Other definitions for pouter that I've seen before include "One having pet" , "Kind of pigeon" , "Petulant-looking" .)

I've seen this clue in the Evening Standard.
