Catbird seat?
I believe the answer is:
perch
'catbird seat?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for perch that I've seen before include "Freshwater fish - roost" , "Bird's resting place or old measure of length" , "What angler may catch" , "Settle" , "Fish and old measure" .)
