tain valleys on the west side of Iliamna Pass, where one specimen was taken 

 July 12. Seen in small numbers in open places in the vicinity of Iliamna 

 Village and along the Nogheling River. None were seen about Lake Clark 

 until August 7, when they suddenly appeared in considerable numbers near 

 the mouth of the Chulitna River, not in the open swamps, but in scattering 

 twos and threes in the thick willow brush, evidently preparing for migration. 

 After this date none were seen. McKay and Johnson found the species breed- 

 ing at Nushagak. 



Hine (1919) obtained specimens at Katmai Bay, June 22 and 

 July 8, 1919, and found the species to be common there. 



We found these sparrows at Snag Point, Nushagak River, on 

 May 25, 1936, and on May 27 and 29 they were common at 

 Ugashik River, being the principal passerine bird in that locality. 



Presumably, the birds here recorded would all be anthinus. It 

 is difficult to know where to place the line of demarcation on 

 Alaska Peninsula between anthinus and sandwichensis , but the 

 Wide Bay specimen suggests that anthinus extends at least that 

 far southwest. 



Passerculus sandwichensis sandwichensis 

 Unalaska: Saksagada (Wetmore) 



This is the largest of the Savannah sparrows, and it has the 

 longest bill. In a large series from Unalaska, and many more 

 from other localities, the bill measures from 11 to 12 mm. long — 

 only five specimens in a series of more than 80 had a bill shorter 

 than 11 mm. A few bills were as long as 13 to 13.5 mm. Length 

 of wing, in this series, is also greater than that of anthinus. 

 There are some, of course, that approach the intermediate status. 

 One specimen (No. 298534, U. S. National Museum) from Izembek 

 Bay has a fairly small bill, but it does not fit into the series of 

 anthinus very well and has a long wing. Another specimen 

 (No. 164927), from Stepovak Bay, has a bill that is 11.5 mm. long, 

 with a slightly smaller body; this bird is larger than anthinus 

 and should be placed with sandwichensis. Thus, the range of this 

 subspecies extends eastward at least as far as Stepovak Bay, and, 

 as there is a specimen of anthinus from Ugashik River, the meet- 

 ing place for these two subspecies would comprise the area 

 between Stepovak Bay and Ugashik River. 



On May 2, 1936, we found Savannah sparrows to be common at 

 Yakutat. They seemed to be large and robust and could have been 

 sandwichensis on westward migration. The bird occurs on Kodiak 

 Island, where it is undoubtedly a migrant. Bischoff collected an 

 immature bird on Kodiak Island in July 1868, and Bretherton 

 obtained an adult in July 1893.
