GEOLOGICAL SUEVEY OF THE TERRITORIES, 



We met with this beautiful warbler but twice during the summer. 

 On the first occasion we were just entering the Lower Geyser Basin, 

 when I observed a pair of these little birds in a grove of small pine 

 trees ; they were hopping about on the ground, and upon my approach 

 flew up into a tree, out of which I shot the male — No, 227, (62347.) 



The second and last time that I saw this species was at the Second 

 Teton Lake, where I saw a male high up in a pine tree. I secured him 

 also.

This is another common species of swallow. We found them very 

 plentiful in the vicinity of Gfeat Salt Lake; thence north to Fort Hall, 

 where they were also abundant. I obtained the nest of this species — 

 No. 58, (16312,)— 5 , No. 147, shot at Eoss Fork, Idaho Territory, on the 

 3d of July. It was composed of mud, and was fastened to the bank of 

 the creek, and about eight feet above the water. The nest contained, 

 two fresh eggs.
