CATALOGUE OF CANADIAN BIRDS. 713 
Three sets of eggs; one of four taken on the upper Hamilton 
River, Ungava, July 3rd, 1894, by Mr. A. P. Low; one of four 
taken at Edmonton, Alta., June 11th, 1897, and one of two taken 
at Trail, B.C., June 14th, 1902, by Mr. W. Spreadborough 
758e. Alma’s Thrush. 
Hylocichla ustulata alm@ OBERHOLSER. 1898. 
Rocky Mountain region of the United States. (Céderholser.) 
This is the common thrush of the Yukon basin, occuring every- 
where from Log Cabin to Circle, perhaps in largest numbers at 
Caribou Crossing and Lake Marsh. Fifteen miles above Fort 
Yukon I took one and saw others, August 2Ist. We saw many 
nests, usually 6 to 10 feet from the ground in thick growths of 
young spruces, but none contained eggs. A nest containing four 
young just hatched, which I found at Caribou Crossing, June 25th, 
was about eight feet from the ground ina thicket of small spruces. 
The nest resembled that of H. mw. swainsoni. At Miles Cafion 
July 11th, we saw young able to fly. Osgood took young in 
spotted plumage, July 31st, but those taken August 20th had 
assumed first winter plumage. They were usually silent by day, 
but sang frequently during the short nights. At Caribou Cross- 
ing, the last day of June, their song could be heard constantly 
from 8 p.m. to 8 a.m.,one taking up the strain as another stopped. 
The song is much superior to that of Hyloctchla aonalaschike and 
almost equal to that of HW. fuscescens. It has whispered notes like 
that of H. mustelinus. By the middle of July the song season was 
practically over though we heard one of the birds singing, July 
23rd. When the nights became really dark in August, I often 
heard the call-note of this bird near our camp between 2 and 3 
a.m. (Bishop.) An adult male from Sheep Creek, Kenai penin- 
sula, July 5th, 1901, extends the breeding range of this form. 
Several seen on Kenai during the summer. A nest containing two 
fresh eggs was found the latter part of June. (Chapman.) 
759. Alaska Hermit Thrush. 
Hylocichla guttata (PALLAS) BREWSTER. 1902. 
Occasionally seen in the thick brush at Hastings, Burrard Inlet, 
in April, 1889; seen on nearly all the mountains at an altitude of 
3,000 feet at Chilliwack Lake, B.C., in July, Igor; first seen on
