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. (YTurner.) We collected a female and a set of 
four fresh eggs at the falls at Glacier above Skagway, Alaska, June 
8th, 1898; a single ouzel seen further down the river, June roth, 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 witha 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 Mcliwraith’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
