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 moun- 

 tains; it is not common but 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 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. {Bishop:) 



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

 esting account of the nesting of this species in East Hapijlton, 

 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 i860, which is all we know of 

 the mocking bird in western Ontario at present. {Mcllwraith.)
