62 The Ottawa Naturalist. [July 



This Warbler shows a decided preference for hemlock 

 growths, and is locally common wherever this tree occurs in 

 abundance. 



Seiurus noveboracensis, Water-Thrush. 



" Summer resident ; scarce."* 



I have found this species breeding fairly commonly in suit- 

 able localities, throughout the district. It prefers swamps of 

 mixed ash and cedar where the rank growth of nettles half 

 conceals stumps and upturned roots. This species frequently 

 associates with the Canadian and Mourning Warblers. 



Oporornis Philadelphia, Mourning Warbler. 



"Transient visitant; scarce."* 



I have found this Warbler to be an almost equally common 

 summer resident with the Water-Thrush. It does not always 

 confine itself to swamps, however, as, on June 9th, 1905, I 

 flushed a female from a typical nest and four fresh eggs, built in 

 an isolated clump of gcldenrod, sheltered by small sized hazel 

 bushes, almost at the summit of the pine-fringed, rocky .western 

 spur of Mount Royal. 



Wilsonia canadensis, Canadian Warbler. 



" Summer resident ; scarce."* 



I should class this species as somewhat mere numerous 

 than the two last mentioned. Its bright song is to be heard in 

 nearly all of our cedar swamps and occasionally I have found it 

 domiciled in wet alder growths. 



Toxostoma rufum, Brown Thrasher. 



" Summer resident ; common."* 



For some unaccountable reason this bird has apparently 

 disappeared from the vicinity of Montreal. On 1st June, 1897, 

 I flushed one from its nest and four eggs, in a hawthorn bush 

 on the slope of Mount Royal. Previous to 1897, I had noticed a 

 few pairs each season but have seen none since. 



Nannus hvemalis, Winter Wren. 



"Transient visitant; common."* 



I have only once examined a nest but have heard its song 

 throughout the nesting season in various cedar swamps in the 

 vicinity of Montreal. 



Sitta carolinensis, White-breasted Nuthatch. 



"Permanent resident; common spring and fall migrant, 

 but scarce summer resident."* 



The above coincides with the vocal activity of this species.
