Birds' homes (5)
I believe the answer is:
nests
'birds' homes' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nests that I've seen before include "Settles comfortably into, as birds do" , "Lodges" , "Structures for laying eggs" , "Sets of small tables that fit closely together" , "Eyries" .)
