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 an'ives 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 lo 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. u. swainsoni. At Miles caiion 

 July nth, 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 Hyiocichla aonalaschikce and 

 almost equal to that of H. 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 

 heaird the call-note of this bird near our camp between 2 and 3 

 a.m.. (Bishop.) An adult male from Sheep creek, Kenai penin-
