Minot on Colorado Birds. 
above the sea, and, in fact, nearly on a level with the summit of 
Mount Washington. Here I spent most of June, making one ex- 
cursion up Pike’s Peak, and two, in the last week, to the Seven 
Lakes, which lie over 11,000 feet up, and about 500 feet below 
timber line, suggesting, with their swampy moorlands and spruce 
timber, the Adirondacks, — for instance, the Saint Regis Lakes. 
1. Turdus aonalaschkae auduboni, Ridg. Hermit Thrush. — 
Abundant at Boulder, May 31, in the groves along the town creek and 
elsewhere, associated with an equal number of Swainson’s Thrushes, 
many Audubon’s W arblers, a few Snow-birds, and perhaps a Lincoln’s 
Sparrow, besides a flock of Cassin’s Finches in the fields, — all brought 
down, I suppose, by a cold storm, above the plains of snow, that on the 
mountains may have been heavy. I found them all again on the bright 
morning of June 1, before leaving town. On Pike’s Peak I neither saw 
nor heard the Hermit Thrush. 
2. Turdus swainsoni, Cab. Swainson’s Thrush. — Common 
summer residents. Established by May 20, above 8,000 feet. Abundant, 
however, at Boulder, May 31, as related above. On Pike’s Peak, June 
21, singing plentifully at evening from 9,500 to 10,500 feet up. 
3. Cinclus mexicanus, Swain. Dipper. — ■ Do more than one pair of 
these birds ever inhabit the same stream or district ? I think not. I found 
one pair to every clear, forcible mountain stream ; though these may have 
occupied merely one section. Ho matter how swift his flight, and how 
tortuous the stream, the Dipper always follows it closely, never taking a 
“ cross-cut,” and never flying much above it, except to scale a fall. In 
“ ducking,” as he does constantly when perched, he often does not bend 
the legs, but merely compresses the body, and slightly spreads the wings. 
He can climb, for sometimes he runs down a slope of rock to the water’s 
edge, and scrambles back again. His ordinary notes are a sharp chip , 
and a chatter. In June his song is rarely to be heard. He is so active 
and unsuspicious that he may readily be traced to his nest, which is usually 
built near some fall. The only one I took was quitted by the young in 
the last week of June, when I found the bottom or bedding gone. Did the 
parents, as a sanitary measure, remove this, with a view to future occupa- 
tion ? This nest is a sort of compressed globe, about seven inches by ten, 
with a circular entrance in front, four inches in diameter. It was built of 
moss, dry grasses, and some leaves, all cemented with mud, in a rift of 
rock, some five feet above the water, in a chasm just below a high cascade. 
It was completely hidden from any ordinary human point of view. 
4. Saxicola cenanthe, Bechst. Stone-chat. — One specimen at 
Boulder, May 14, 1880. Considering how admirably suited the foot-hill 
slopes of the Rocky Mountains seemed to the wants of the Stone-chat, as 
exemplified in England, I looked hopefully for other specimens. Though 
I found none, t believe that this pretty species will prove to be of circum-
