Accommodation that's barred for fliers (8)
I believe the answer is:
birdcage
'accommodation' is the definition.
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for birdcage that I've seen before include "Enclosure for an avian" , "Enclosure for a budgie, say" , "Polly's home perhaps" , "arrangement of bars for singer" , "Small aviary" .)
