An immature specimen from Admiralty Island, Alaska (No. 187748, 

 U.S.N.M.), is very dark on neck and back, but this difference is 

 apparently not more than individual. This race is confined, so far 

 as known, to a narrow strip of country along; the coast and to the 

 islands, from the State of Washington to Alaska. 



Ten specimens have been examined, from the sulijoined localities, 

 breeding records being followed by an asterisk:
