Duck in Brunei Dermott discovered (5)

I believe the answer is:

eider

'duck' is the definition.
(eider is a type of duck)

'in brunei dermott discovered' is the wordplay.
'in' indicates the answer is hidden within the clue.
'EIDER' is hidden in the letters of 'brunei dermott discovered'.

(Other definitions for eider that I've seen before include "Down-producing duck" , "Large sea duck" , "Quilt- furnishing duck" , "Species of duck" , "Sea bird" .)

I've seen this clue in the Sydney Morning Herald.
