buildings, and the birds themselves rarely strayed far outside the 

 town. One nest noted, which was placed upon a telephone insulator 

 on the government agent 's office, must have been used for some years, 

 for it was built up to a height of six inches or more. 



Flocks of migrating swallows that were seen in August at several 

 points down the river were apparently of this species, but could not 

 be satisfactorily identified. These flocks were invariably traveling up 

 stream. In the harbor at Wrangell, August 16, were large numbers 

 of barn swallows, mostly young, flying about and alighting on the ship- 

 ping and wharves. On Sergief Island, during the next two weeks, the 

 species was seen frequently, traveling southward in large flocks. The 

 flocks diminished in numbers toward the end of the month; the last 

 bird observed was a single individual on August 30. 



Two specimens of the barn swallow were preserved, an adult male 

 and an adult female, both taken at Telegraph Creek on June 11 (nos. 

 40112, 40113). 



Iridoprocne bicolor (Vieillot). Tree Swallow 

 Just one pair seen, at Sawmill Lake, near Telegraph Creek. They 

 were nesting in an old woodpecker hole in a dead birch stub at the 

 margin of the lake. A pair of mountain bluebirds were nesting in 

 the same stub. The swallow's nest held three eggs on June 11; the 

 complete set of seven, with the nest, was taken on June 17 (no. 1816). 

 The nest was built largely of coarse grass and pine needles, mixed 

 with some mammal hair, and was lined with large duck feathers. The 

 two parent birds were taken (nos. 40114, 40115). 



Tachycineta thalassina lepida Mearns. Northern Violet-green 



Swallow 



Abundant about Telegraph Creek. Nesting in crevices in the build- 

 ings and in a cliff overlooking the town from the northeast. The birds 

 were settled in their nesting sites when we arrived (May 23), but indi- 

 viduals collected on June 8 had not yet laid their sets. The species 

 was fairly abundant at Glenora. At Doch-da-on Creek, the latter part 

 of July, violet-green swallows were seen frequently. 



At Sergief Island, toward the end of August, the species was 

 encountered on so many occasions that it seems probable that it is of 

 regular occurrence as a migrant at some points, at least, on the coast 

 of southeastern Alaska, despite the paucity of records. As far as I 

 know, my own observations on the Chickamin Eiver and at Thomas
