FAUNA OF THE ALEUTIAN ISLANDS AND ALASKA PENINSULA 213 



Iridoprocne bicolor: Tree Swallow 



On May 13, 1937, we saw two of these birds at Point Gustavus, 

 Icy Strait. Friedmann (1935) mentions a reported sight record 

 of a family group on the northern part of Kodiak Island on July 

 27, 1929. Osgood (1904) identified a few at Iliamna Village. On 

 May 25 and 26, 1936, we observed at least six at Snag Point, 

 Nushagak River. Turner, also, observed these birds on Nushagak 

 River (1886). On July 17, 1940, Gabrielson found these swallows 

 common at Dillingham; he saw some at Brooks Lake, July 20, 

 and noted one at Iliamna Lake, July 24. 



There is a specimen in the National Museum taken by G. D. 

 Hanna at Lake Aleknagik, June 17, 1911. 



As would be expected, the tree swallows are confined to the 

 wooded basal part of Alaska Peninsula. 



Riparia riparia: Bank Swallow 

 Riparia riparia riparia 



Aleut (dialect uncertain) : Agdmdax' (Jochelson, for "the swallow") 



In his work at the base of Alaska Peninsula, Osgood found that, 

 on the Nushagak River between the mouth of the Tikchik and 

 Kakwok, most of the high banks "were drilled along the upper 

 edges with their characteristic holes," and he mentions that 

 specimens of the bank swallow were taken at Nushagak by Mc- 

 Kay. Osgood obtained a specimen at Lake Iliamna, July 17, 

 1902. Turner (1886) found them "quite plentiful on Nushagak 

 River." 



On June 17, 1940, Gabrielson observed two bank swallows at 

 Karluk weir on Kodiak Island. On June 19, he noted 5 of these 

 birds at Chignik Bay; on June 21, he saw at least 12 at Morzhovoi. 

 Bay; on July 17, he saw several at Dillingham; on the next day 

 they were common at Wood River Lakes; on July 21, they were 

 noted at Brooks Lake; and on July 21, they were common in the 

 tundra region between Becharof Lake and Egegik cannery. 



On May 30 and June 4, 1925, I found several bank swallows 

 along the upper part of the stream flowing into Izembek Bay 

 from Aghileen Pinnacles. Near Point Grant, in Izembek Bay, 

 there was a nesting colony on a steep bank of one of the islands. 

 A bank swallow was seen on Amak Island, July 7, and, on August 

 9, several were seen at False Pass. 



In 1911, Wetmore collected specimens of bank swallows nest- 

 ing in small numbers at some sandy cutbanks at the head of 

 Morzhovoi Bay. Gianini (1917) saw one at Stepovak Bay. Beals 

 and Longworth reported, May 22, 1941, at False Pass that "First
