Airborne crossing? (7)
I believe the answer is:
pelican
'crossing?' is the definition.
(pelican crossing is a type of road crossing)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for pelican that I've seen before include "Large waterbird" , "Large-pouched bird" , "In place (anag.)" , "Seabird having a large bill with a pouch for fish" , "Large bird with enormous beak" .)
