CATALOGUE OF CANADIAN BIRDS. 663 
young bird. Near Forty-mile creek, Tatondu river and Charlie 
creek water-thrushes were again met with. At Circle I saw several 
August 16th-20th, took one 15 miles above Fort Yukon, August 21, 
and saw two in a thicket at the Aphoon mouth, August 28th. The 
young in full plumage taken on the Yukon are clove-brown above, 
including wings and tail—far darker than is usual in notabilis— 
and have darker streaks below. (Bishop.) I have a nest and four 
eggs taken by Rev. Mr. Stringer at the mouth of Mackenzie river, 
June roth, 1899. Nest on the ground under willows near the river 
bank. (W. Raie.) For a few days after our arrival in August 
at the site of our new winter quarters on the Kowak, Kotzebue 
sound, Alaska, this species was moderately common. It frequented 
the alder and willow thickets along the streams and was shy and 
restless. The species arrived in the spring on May 22nd, and was 
henceforth common, especially in the Kowak delta in June; but it 
was not detected west of the tree limit. (Grinnell.) An immature 
male was taken at Homer, Kenai peninsula, Alaska, August 18th, 
1901. This is undoubtedly a rare bird at Homer, as one specimen 
was all I noted. (Figgims.) One adult male taken at Seldovia, 
Alaska. (Anderson.) 
676. Louisiana Water-Thrush. 
Seiurus motacilla (VIEILL.) BONAP. 1850. 
A rare summer resident in Middlesex co., Ont.; not noted further 
north. (W. E. Saunders.) There are two records for Toronto, 
Ont., a female taken by Mr. Ernest Seton, Aug. 23, 1888, and an- 
other female taken by Mr. C. W. Nash at Kew Beach, East Toronto, 
May 8, 1900. (J. H. Fleming.) The large-billed water-thrush 
is by no means so common a bird in Ontario as the preceding species, 
but along the southern border of the province, wherever there is a 
rocky ravine, its loud, clear notes are almost sure to be heard in the 
spring, mingling with the sound of the falling water. It arrives from 
the south early in May and leaves in September. (Mcllwraith.) 
CCLV. OPORORNIS Bairp. 1858. 
677. Kentucky Warbler. 
Oporornis formosa (WILS.) BAIRD. 1858. 
Taken at Quebec by Mr. Nelson. (Dionne.) Only one specimen 
known from near London, Ont.; this was taken by Rokert Elliott
