High home (4)
I believe the answer is:
nest
'high home' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nest that I've seen before include "home for 22d [VIPERS]" , "Sent to avian home" , "Bird's retreat" , "Snug retreat" , "Home of twigs, perhaps" .)
