Duck down in the bedroom (5)
I believe the answer is:
eider
'duck down' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for eider that I've seen before include "Sea bird" , "Sea duck with soft down" , "Quilt- furnishing duck" , "Type of duck" , "I've noted down" .)
