Get down from this? English clubs out of drink (5)

I believe the answer is:

eider

'get down from this?' is the definition.
(down feathers may come from an eider duck)

I cannot understand how the rest of the clue works.

(Other definitions for eider that I've seen before include "Variety of duck" , "Large sea duck" , "Quilt- furnishing duck" , "Duck noted for down" , "Sea duck with soft down" .)

I've seen this clue in The Guardian.
