574 GEOLOGICAL SURVEY OF CANADA. 
common and widely distributed species of the swallows throughout 
the north. In Alaska it is found along the southeastern coast, ex- 
tending 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 locations occur. (Nelson.) 
Breeding abundantly about the town of Sitka, Alaska, under the 
eaves of buildings; a few pairs found nesting on the cliffs on the 
islands out in the bay. This swallow was seen almost daily at Cape 
Blossom, Kotzebue sound, Alaska; the species was seen on the upper 
Kowak and in the delta of that river in June. (Grinnell.) This 
bird arrives at St. Michael about June, and as soon as the ground ig 
thawed, begins to build. (Twrner.) 
BREEDING NoTEs.—tThe nest of this species is built of mud mixed 
with hay or straw and lined with fine grass and a thick bed of feathers. 
Eggs, five; white, spotted with reddish-brown. (G.R. White.) Not 
nearly so plentiful at Scotch Lake as lunijrons. Always building 
inside buildings. Eggs, from four to six, placed in a soft feather- 
lined nest of mud and hay. Some pairs raise two broods in one 
season in the same nest. One pair abandoned the second brood and 
went south, September 9th, 1901; the young died in the nest. (W. 
H. Moore.) I was told by missionaries that the swallows nested in 
the deserted Eskimo igloos, building their mud nests against the sides 
near the roof. On July 1st, 1899, I found a barn swallow’s nest 
built on a beam in the house of a small river steamer, stranded at the 
side of Mission inlet. The nest was constructed as usual of a mix- 
ture of mud and grasses with a lining of finer grass and a large quan- 
tity of white ptarmigan feathers almost burying the eggs. (Grin- 
nell.) Nests oblong and attached to the walls or to the rafters of 
barns and other buildings; or round and placed on the beams. They 
are made of mud arranged in small pellets formed and mixed with 
grass and have a lining of feathers and hair. Four to six eggs in 
the set at Ottawa and at Lake Nominingue, 100 miles north of it, 
in June and July. (Garneau.) 
613a. Alaskan Barn Swallow. 
Hirundo erythrogaster unalaschkensts (GMEL.) PALMER. 1899. 
A few barn swallows were flying over the marshes of Chilcat inlet, 
June 1st, 1899; I heard they were common at White Pass City, June
