ocr., 1899.) BIRDS, 133 
They were usually seen in early evening when they came to drink from 
the little streams in the forest, and were always silent and rather shy. 
Late in July and early in August they were seen with arctic bluebirds 
by Walter K. Fisher at and below timberline near Mud Creek Canyon. 
They probably winter in the junipers in Shasta Valley, where W. H. 
Osgood saw them September 17 to 20, and where [ saw dozens feeding 
on the juniper berries and singing freely September 29, Late in July, 
1883, C. H. Townsend found one of these birds “frozen in the snow and 
ice which filled the crater of the extinct voleano of Shasta.” 
133. Hylocichla aonalaschke auduboni. Dwarf Hermit Thrush. 
Evidently breeds in the dark Shasta fir forest of the mountain and 
in the damp forest of white aud Douglas firs near Sisson Tavern, where 
Miss Merriam heard them in full song the middle of July. At Wagon 
Camp W. H. Osgood shot one July 17; and near Squaw Creek Camp 
I shot another September 20. C. H. Townsend records it from the 
southern slope of Shasta under date of July 25. 
134, Merula migratoria propinqua. Western Robin. 
Robins were fairly common at Wagon Camp, where we heard their 
evening song the day of our arrival, July 15, and where they were seen 
carrying food to young July 26 (F. A. M.). Higher up they were seen 
from time to time, but were not common. Along the upper part of 
Mud Creek Canyon Walter K. Fisher found them “fairly common but 
erratic” the latter part of July and first few days of August. At Squaw 
Creek Camp, in the alpine hemlocks, we saw a flock on the morning 
of August 12, and others September 15. Just below timberline on 
Panther Creek a few were seen migrating September 18. In Shasta 
Valley they were common among the juuipers September 29. At Sis- 
son they are common breeders, and a few were seen whenever any of 
our party were there, from July 14 until the end of September. A nest 
containing three eggs was found July 13 by W. H. Osgood. 
135. Sialia mexicana occidentalis. Western Bluebird. 
A common breeder at Sisson, where families, including lately fledged 
young, haunted the fences the first half of September (R. T. Fisher). 
In Shasta Valley W. H. Osgood found them common September 17 to 
20, and a few small flocks were seen by me among the junipers Septem- 
ber 29. At Sisson the species was common tie latter part of Septem- 
ber. In 1883 a nest containing nearly grown young was found by C. 
H. Townsend in a post hole in the ground at Sisson Tavern late in 
July. 
136, Sialia arctica. Mountain Bluebird; Arctic Bluebird. 
A common breeder on the higher slopes of Shasta, where they were 
constantly seen in July and early August, but rarely afterwards. On 
our first visit to timberline, July 17, they were very abundant on the
