Birds; toys (5)
I believe the answer is:
kites
I believe this is a double definition.
'birds' is the first definition.
(kite is a kind of bird)
'toys' is the second definition.
(kite is a kind of toy)
(Other definitions for kites that I've seen before include "Large hawks or flying toys" , "Aerial toys; birds" , "aircraft" , "Birds of prey - flying toys" , "More than one toy" .)
