194 GAME BIRDS OF CALIFORNIA 



Franklin Bay on the Arctic coast. The nest was a mere depression in 

 the ground fifty yards from the beach and composed entirely of down. 



It [the King Eider] is a deep water duck and feeds mostly on mussels 

 which it is able to procure, it is said, in water upward of 150 feet in depth, 

 and occasionally is caught like the Old-squaw in the deep water gill nets of 

 the lake fishermen. In the breeding season the males go into the ' ' eclipse ' ' 

 plumage and flock together on the open sea. The female lines her nest with 

 down as do the other species of eider, thus furnishing the famous eider down 

 of commerce, which is gathered by the natives of Iceland, Greenland and 

 Norway. This is taken chiefly from the Greenland and European eiders, each 

 nest yielding about five ounces of down in a season (Eaton, 1910, p. 220). 



The King Eider even in the far north is of little value as a game 

 bird, so its extreme rarity within our state is of small consequence to 

 hunters. Occurrences as far south as California are of interest chiefly 

 because they are out of the ordinary. No economic importance can 

 be ascribed to a bird of such rarity.
