mountain streams from Banff through the Rocky mountams to tha 

 Selkirks and Gold range. Its habit of Hving beside and behind 

 waterfalls and small cascades adds a great deal of interest to a study 

 of its habits ; one nest found in the Kicking Horse valley was placed 

 on a ledge behind a small waterfall and contained young birds on 

 August 13th, 1885; at a distance it looked like a large mass of wet 

 moss, but on examination it proved to be a nest shaped like an oven. 

 (Macoun.) Very common in the rocky creeks west of the Columbia 

 river on the 49th parallel in the summer of 1902; taken in Eagle 

 river in the Gold range, B.C., on April 5th, 1890; common on the 

 Elk river, B.C., May, 1904; one seen on Whipsaw creek and one on 

 Skagit river, B.C., July 15th, 1905; one seen on a small stream at 

 5,000 feet altitude, July 25th, 1905; a few were seen in the little 

 stream below Spence Bridge, B.C., in May, 1889, and a few at the 

 head of the North arm of Burrard inlet, B.C., in April, 1889; quite 

 common on the Chilliwack river and the streams flowing into it in 

 the summer of 1901; one seen near Goldstream, Vancouver island, 

 June 2nd, 1893; also saw one on Sooke river, on September 5th, 

 where I heard it singing for the first time, I have heard it said they 

 were good singers and so they are ; their song resembles that of the 

 cat-bird very much, in fact so much so that if I had not seen the 

 bird sitting on a stone I should have put it down for that bird; 

 they seem to do most of their singing in the fall and winter. (Spread- 

 borough.) On July 1 6th, 1887, a nest of this species was found on 

 the stringer of a bridge over a stream emptying into Cameron lake, 

 at the base of Mount Arrowsmith, Vancouver island ; it was built of 

 moss and quite large, but very compact in the centre, but with the 

 dome over it; owing to its position in a rapid torrent the eggs or 

 young were not seen as we looked through a chink at the nest; as 

 we camped at the bridge we had the bird under observation for two 

 days. (Macoun.) 



Three specimens of this bird were procured by Mr. Drummond 

 near the sources of the Athabaska river, on the eastern declivity of 

 the Rocky mountains, between latitude 54° and 56°. (Richardson.) 

 The only specimen seen was shot at Ducks, B.C. (Streator.) To be 

 found in nearly every mountain stream throughout British Columbia. 

 (Fannin.) Very common along all the rivers in British Columbia. 

 (Lord.) Resident at Chilliwack, but not common ; common at Lake 

 Okanagan, B.C., sings all winter; in the Cariboo district of British
