40° below zero. It seems to be very little affected by the extreme 
cold of our winters. (Velson.) This species was obtained from 
several localities; it inhabits rocky creeks flowing from the moun- 
tains; it is not common but is a permanent resident and breeds 
here. (Zurner.) 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 loth, was pro- 
bably the mate of the one taken. Osgood also took one at Un- 
alaska, October 5th. (Dzshop.) 
BREEDING Notes.— Breeds near Banff, Rocky Mountains, mak- 
ing a large nest of moss with a side entrance which it usually 
builds close to a cascade either ina tree-root or on a ledge of 
rock. The nest is covered with moss and kept green by the fall- 
ing spray from the mountain stream. (W. Raine.)

In MclIlwraith’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 have not been observed. In the “ Birds of 
Western Ontario” mention is made of one specimen being taken 
by Mr. Sandys at Chatham, Ont., in 1860, which is all we know of 
the mocking bird in western Ontario at present. (A/cL/wraith.)
