Unfortunately sent home (4)
I believe the answer is:
nest
'home' is the definition.
(a bird's home)
'unfortunately sent' is the wordplay.
'unfortunately' indicates anagramming the letters (a bad or unfortunate spelling).
'sent' with letters rearranged gives 'NEST'.
(Other definitions for nest that I've seen before include "Place of retreat" , "Stack of tables" , "Cosy retreat" , "Sent to avian home" , "Bird's retreat" .)
