Bunting festooned in door to landing (7)
I believe the answer is:
ortolan
'bunting' is the definition.
(ortolan is a kind of bunting)
'festooned in door to landing' is the wordplay.
'festooned in' says the answer is hidden in the clue (to festoon can mean to cover with decorations).
'ORTOLAN' is hidden in the letters of 'door to landing'.
(Other definitions for ortolan that I've seen before include "high-flying singer" , "Bobolink" , "Small songbird" , "European bunting" , "Type of bunting eaten as a delicacy" .)
