Bird in tree -- a glede? (5)
I believe the answer is:
eagle
'bird' is the definition.
(eagle is a kind of bird)
'in tree a glede?' is the wordplay.
'in' says the answer is hidden in the clue.
'EAGLE' can be found hidden inside 'tree a glede'.
(Other definitions for eagle that I've seen before include "high-flier" , "may be soaring" , "Two under in 20 across" , "ten-dollar coin" , "Large birds of prey." .)
