Settles for the night (6)
I believe the answer is:
roosts
'settles for the night' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for roosts that I've seen before include "Where birds settle to sleep" , "'Rests on a perch, like a chicken (6)'" , "Perches for domestic fowl" , "Stays" , "where people settled?" .)
