CATALOGUE OF CANADIAN BIRDS. 743 
Not uncommon at Prince Albert, Sask.; breeding in the vicinity. 
(Coubeaux.) One specimen secured at Grand rapids of the Sas- 
katchewan. (Nutting.) Eastgate shot a juvenal in a thicket of 
poplars on the summit of the Cypress hills, July 27, 1906. (A. C. 
Bent.) This thrush arrives on the banks of the Saskatchewan in 
May and during the summer haunts the alder thickets and dense 
willow groves that skirt the marshes. (Richardson.) North to 
Lapierre House, on the Mackenzie river; abundant. (Ross.) A 
common breeding bird from Clinton, B.C., to Quesnel. (Brooks.) 
Southern mainland, east of Coast range, B.C. (Fannin.) A 
female and young male in nesting plumage were shot at Nelson, B.C., 
where they were fairly abundant. (Rhoads.) On the coast of 
Behring sea, where the grey-cheeked thrush is abundant, this species 
is very rare or does not occur at all. In the interior, however, it 
appears to increase in numbers as the distance from the sea-coast 
increases. (Nelson.) A single specimen was obtained from Fort 
Yukon, Alaska; it is apparently not common in any district of 
Alaska. (Turner.) This is the common thrush of the Yukon basin, 
occuring everywhere from Log Cabin to Circle, perhaps in largest 
numbers at Cariboo Crossing and Lake Marsh. Fifteen miles above 
Fort Yukon I took one and saw others, August 21st. 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 Cariboo Crossing, June 25th, 
was about eight feet from the ground in a thicket of small spruces, 
The nest resembled that of H. uw. swainsont. 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 Cariboo 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 Hylocichla aonalaschike and 
almost equal to that of H. fuscescens. It has whispered notes like 
that of H. mustclinus. 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.. (Bzshop.) An adult male from Sheep creek, Kenai penin-
