Porridge for a flyer (4)
I believe the answer is:
bird
'porridge' is the definition.
(I've seen this before)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for bird that I've seen before include "Dawn chorus etc - book by Sebastian Faulks" , "Member of class Aves" , "Flying creature" , "Prison sentence - hawk, perhaps" , "chat, perhaps?" .)
