Leave supports for little birds (8)
I believe the answer is:
goslings
'little birds' is the definition.
'leave supports' is the wordplay.
'leave' becomes 'go' (to go is to depart or leave).
'supports' becomes 'slings' (sling is a kind of support).
'go'+'slings'='GOSLINGS'
'for' is the link.
(Other definitions for goslings that I've seen before include "Young geese" , "Chicks - signs log (anag)" , "Glossing over little geese" , "birds" , "Greenhorns" .)
