Walk across the road with bird at Checkpoint Charlie (7,8)
I believe the answer is:
pelican crossing
'checkpoint charlie' is the definition.
The definition suggests a singular noun which matches the answer.
'walk across the road with bird' is the wordplay.
I cannot really understand how this works, but
'bird' could be 'pelican' (pelican is a kind of bird) and 'pelican' is located in the answer.
The remaining letters 'crossing' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'at' acts as a link.
Can you help me to learn more?
(Other definitions for pelican crossing that I've seen before include "safe place to walk" , "I can stop the traffic" .)
