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 i6th-2oth, 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 loth, 1899. Nest on the ground under willows near the river 

 bank. {IV. Raine.) 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 moderatel}' 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 i8th, 

 1901. This is undoubtedly a rare bird at Homer, as one specimen 

 was all I noted. {Figgins.) One adult male taken at Seldovia, 

 Alaska. {Anderson.) 



676. Louisiana Water-Thrush. 



Seiurns 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. (/. 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 Baird. 185S. 



677. Kentucky Warbler. 



Oporornis formosa (WiLS.) Baird. 1858. 

 Taken at Quebec by Mr. Nels6n. (Dionne.) Only one specimen 

 known from near London, Ont. ; this was taken by Robert Elliott
