CATALOGUE OF CANADIAN BIRDS. 113 



reported by Messrs. DUNLOP and WINTLE as appearing every 

 spring on Nun's Island, off Montreal. It is a rare summer resi- 

 dent of Manitoba, and westward to the Rockies, and is fairly 

 common in British Columbia, north to Kamloops. Winters 

 south to Guatemala. 



Certhia familiaris americana. 



BROWN CREEPER. 



The Creeper is an uncommon summer resident of the Mari- 

 time Provinces, and is rare in Manitoba ; but in both Quebec and 

 Ontario it is common, and is found in the southern portions of 

 the latter Province during the entire year, though its general 

 breeding ground is farther north. In British Columbia it is fairly 

 common, north to Kamloops. 



Sitta carolinensis. 



WHITE-BREASTED NUTHATCH. 



This species is said to occur throughout the southern portions 

 of the Dominion, from the Atlantic to the Rockies, but I have not 

 seen any records of it having been taken west of the Georgian 

 Bay. It is sedentary in Southern Ontario, and quite common, 

 and in Quebec and the Maritime Provinces it is a fairly common 

 summer resident. 



Sitta carolinensis aculeata. 



SLENDER-BILLED NUTHATCH. 



A summer resident from Manitoba to the Pacific, being most 

 abundant on the western slopes of the Rocky Mountains and the 

 eastern slopes of the Cascades.
