possibly deterred the usually venturesome bird from coming there. This is the only 

 species of Swallow found on any of the Aleutian chain proper and is not known Avcst 

 of the island of Unalaska. While at Atkha Island in 1S79, and at Atlu Island in 

 1880 and 1881, I made special inquiry regarding this bird and only those persons who 

 had visited Unalashka Island and had seen the bird there knew of its existence. The 

 absence of knowledge of this bird in both of these places shows conclusively that neither 

 the Barn-Swallow nor its congeners visit the islands in question. At Nusha"ak 

 (Bristol Bay) the species is found in considerable numbers, and breeds there, as I saw 

 a nest in June 1878." Mr. Townsend says that it was a common bird on the Kowak 

 River in Korthern Alaska, breeding there. 



Mr. Nelson's note is as follows : — "(Esquimaux Tu-ln-kugh-u-nd-guk) This Inrd is 

 the most common and widely distributed of the Swallows throughout the north. In 

 Alaska it is found along the south-eastern coast, extending thence over nearly the entire 

 Aleutian chain, and north along the coast of the mainland to Kotzebue Sound, and 

 thence east throughout the Territory wherever suitable situations occur. It arrives at 

 St. Michaels from May 17 to 26, and leaves toward the end of August. At Port Clarence, 

 in Bering Straits, Dr. Adams found them breeding in the summer of 1851. At 

 Unalaska, June 2 and 3, 1877, I saw a number of these Swallows skimming about and 

 over the village. Dall found them at various points on the Aleutian Islands, and they 

 nest at Unalaska. The latter reports seeing a Swallow at Atkha Island, at the extreme 

 western part of the chain, which was undoubtedly this species. About the middle of 

 May they arrive at Nulato, where they breed, as they do also at Fort Yukon and the 

 other fur-trading stations along the Yukon." 



The late Dr. Adams gave the following note in a paper on the birds of Miclialaski : — 

 " Early on the morning of the 31st of May, 1851, eight or ten of these birds arrived at 

 Michalaski. I had been wandering about the neiglibourhood the whole of the previous 

 day, and did not meet ■nith one of them, so that they must have journeyed in a flock. 

 They immediately set to work about repairing their old nests, which were placed in an 

 outhouse, under the eaves of the buildings, and in some of the loopholes for musketry 

 in the block-houses. When they find a horizontal surface on which to build, the nest is 

 very slight and shallow ; but those under the eaves are large and well-built. \^\-\ much 

 resembling those of H. tirhica, but open at the top. There were so many oUl nests that 

 very few of them built new ones, merely rejjairing and relining the old ones. The nest 

 is built entirely of mud lined with a tliick bed of featliers. One pair that had been fre- 

 quently disturbed whilst building in an exposed situation left their unlinished nest and 

 built another in the root of a tuft of long grass whicli liung down iVoni the inside of the 

 roof of an outhouse. This one they concealed so avtrully, by suspendinL;- Iuhl;- st raws iVoiu 

 its outer surface, that it Avas only by watching tii(> l)irils thai l discovered it. At thi- 

 time of the arrival of these birds the weather was line and wai'in, and their iiunil)crs were 

 soon greatly increased; but in a ^cvc days the weather Ijci-amc cold and wet, and all the 

 Swallows left off building. One pair left their half-Iiuishcd nest, and built upon a rafter
