saved. The birds live entirely about the bluffs aud even seek their food under the 

 huge bowlders at the bases of the cliffs, where they enter the crevices and, remaining 

 under some minutes, reappear some ten or more feet away. Eggs: "Dull white with 

 a very few minute dots of reddish, so few and small as to be easily overlooked, 0.68 

 by 0.51, 0.60 by 0.50."— (Allen.) No. 54447, im. S , Type, August 17, 1868, St. George,

Similar to H. erythrogastra, but larger, with longer wings and tail and relatively 

 smaller bill; white areas of tail larger, with narrow white outer edgings to the 

 leathers. 



Walking along the bluffs near the village of St. George on May 28, 1890, with 

 Mr. Ed. Lavender, we saw a swallow skimming along the edge of the bluff, catching 

 the flies which the warm sun had enticed from the crevices of the rocks. Shortly 

 afterwards it flew just over my head while among the houses of the village. Drs. 

 Noyes and Hereford, who have each spent more than ten years on the islands, assured 

 me that a swallow was unknown there, but later in the evening 1 had the opportunity 

 of showing them the bird on another part of the bluff. It remained about the village 

 for nearly two weeks. On June 4, while standing on Black Bluff's, St. Paul, I watched 

 a swallow coming in to the land and then fly northward up the island. 



I found a nest at Unalaska, on August 13, containing three large young, a male 

 and two females, and secured the adults also. The nest is of mud held together by 

 grass rootlets. It is 9 inches wide and 4 inches deep; the cavity is 2J inches in 

 diameter and IJ inches deep. Grass rootlets encircle the cavity, which is well-lined 

 with gull and raven feathers. It was built in a large cavity, almost a cave, of a rock 

 on a hillside, and was placed on the slightly sloping face of the back portion, about its 

 center. A slight inequality of the rock face was sufficient to hold it in place. To 

 enter the cavity the birds had to fly to the face of the rock and then dip downward 

 between the rock and many tall plants, which effectually hid the opening. I saw no 

 others.

 times flushed a sparrow which I identified as this species, having seen and collected a 

 number several days before at Unalaska.
