Melospiza lincolnii: Lincoln's Sparrow 

 Melospiza lincolnii lincolnii 



Birds observed in the Cook [nle1 region b\ Osgood evidently 

 were considered to be the typical form, for he says (1001), 



An adult male was taken at Hope August 28, and a few others were seen 

 while we were there. The Bpecimen taken shows none of the characters 

 attributed to Melospiza lincolni striata [gracilis], 



On July 27, 1940, Gabrielson collected a Lincoln's sparrow at 

 the upper end of [liamna Lake, the only record we have for 



the base of Alaska Peninsula. 



Melospiza melodia: Song Sparrow 

 Attu: Chu-gu-chigh 

 Atka: Chig"-wiach 



The song sparrows occupy the Aleutian district (as here 



defined) from Attn Island to Kodiak. Gabrielson and Lincoln 



(1951), who reviewed the Alaskan song sparrows, have char- 

 acterized them as follows, to state the matter very briefly. 



Melospiia melodia maxima 



Described as a new form, differing from stoniku in being 

 browner, with a larger beak. Range extends from Atka to Attn. 



Melospiza melodia sanaka 



Grayer in color. Range extends from Seguam Island, in the 

 Aleutians, eastward to Stepovak K:i\ on Alaska Peninsula and 

 to the Somidi Islands, including other islands south of the western 

 part of the peninsula (Sanak, Shumagins, and many others). 



Melospiza melodia amaka 



This is a new race, described by Gabrielson and Lincoln — 



Resembles max ima from the western Aleutians in color and extensive brown 

 markings, but somewhat more heavily marked with brown than that race 

 both on back and breast; in most available specimens the brown markings 



also somewhat brighter. Closer in color to maxima than to the geographically 

 closer race r,a aahii. Hill short, and stubby as in :;anal:a. Range, routined to 

 Amak Island, a rocky island north of the west end of Alaska Peninsula some 

 15 miles. 



A distinct subspecies that is confined to a single island, such 

 as Amak, may seem incongruous when one considers the exten- 

 sive ranges of the other forms. However, Amak is somewhat
