Steal from home a bird (5)
I believe the answer is:
robin
'a bird' is the definition.
(robin is a kind of bird)
'steal from home' is the wordplay.
'steal from' becomes 'rob' (to rob someone is to steal something from them).
'home' becomes 'in' ('he's home' can mean 'he's in').
'rob'+'in'='ROBIN'
(Other definitions for robin that I've seen before include "Red and brown songbird" , "Day was one" , "Seasonal bird" , "Bird - boy's name" , "Garden bird" .)
