Baby birds? (6)
I believe the answer is:
storks
'baby birds?' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for storks that I've seen before include "Long-legged baby-carrying birds" , "Black and white wading birds" , "Wading birds that bring babies" , "Wading birds with large bills" , "Baby carriers!" .)
