Funny marks left by a bird landing on your face? (9)
I believe the answer is:
crowsfeet
'on your face?' is the definition.
I know nothing about this answer so I can't judge whether this works.
'funny marks left by a bird' is the wordplay.
I cannot really see how this works, but
'bird' could be 'crow' (crow is a kind of bird) and 'crow' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'landing' acts as a link.
Can you help me to learn more?
(Other definitions for crowsfeet that I've seen before include "we produce, with a smile?" , "Footprints" .)
