Crossing bird? (7)
I believe the answer is:
pelican
I believe this is a double definition.
'crossing' is the first definition.
(pelican crossing is a type of road crossing)
'bird?' is the second definition.
(pelican is a kind of bird)
(Other definitions for pelican that I've seen before include "Bird with large pouched beak" , "Large waterbird" , "Nice pal (anag)" , "In place for large-billed bird" , "Large water bird" .)
