Hudson River feeder (6)
I believe the answer is:
mohawk
'hudson river feeder' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for mohawk that I've seen before include "American native; skating step" , "Member of a native American people and a haircut" , "Iroquoian American; skating manoeuvre" , "Native American - punk hairdo" , "Brave" .)
