Columbia it is found in the neighbourhood of running water all 

 winter. (Brooks.) Associated in British Columbia with all dashing 

 streams from the mountains to the sea. (Rhoads.) Common up 

 Seymour creek, B.C. {E. F. G. White.) A dipper was seen and 

 heard several times along a stream emptying into West arm of 

 Cumshewa inlet, Queen Charlotte islands, 1899; several were seen in 

 the mountains near Hope, Cook inlet, Alaska, and a specimen was 

 taken there September 3rd, 1899. (Osgood.) Throughout Alaska, 

 wherever clear, swift-running streams afford suitable locations, this 

 bird is found. It winters in the neighbourhood of St. Michael, and 

 specimens have been brought to me in midwinter when the tempera- 

 ture was at least 40° below zero. It seems to be very little affected 

 by the extreme cold of our winters. (Nelson.) This species was 

 obtained from several localities; it inhabits rocky creeks flowing 

 from the mountains ; it is not common but it is a permanent resident 

 and breeds here. (Turner.) We collected a female and a set of 

 four fresh eggs at the falls at Glacier above Skagway, Alaska, June 

 Sth, 1898 ; a single ouzel seen further down the river, June loth, was 

 probably the mate of the one taken. Osgood also took one at Un- 

 alaska, October 5th. (Bishop.) 



Breeding Note. — Breeds near Banff, Rocky mountains, making 

 a large nest of moss with a side entrance, which it usually builds close 

 to a cascade, either in a tree-root or on a ledge of rock. The nest is 

 covered with moss and kept green by the falling spray from the 

 mountain stream. (W. Raine.)

In Mcllwraith's " Birds of Ontario," page 388, there is an inter- 

 esting account of the nesting of this species in East Hamilton, Ont., 

 in 1883. Mr. Eastwood observed the male early in the season, but 

 the female kept so close that she was seen only once. It was hoped 

 that this pair, or some of their family, would return the following 

 spring to visit their old friends in Ontario, but if they did so they
