Pigeon perch, perhaps (5)
I believe the answer is:
ledge
'pigeon perch perhaps' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ledge that I've seen before include "Surface under e.g. window" , "Ridge or shelf" , "Ability to contain one's emotions" , "Narrow shelf, often attached to window" , "Narrow projecting shelf as from window" .)
