402 NOTES ON THE 



ers. Remaining almost constantly concealed from view in the 

 leaves and fine branches of the undergrowth of border land to 

 denser forests, it flips suddenly up into the air of the open 

 places above the undergrowth, and seizing its insect, disap- 

 pears as quickly in the thicket again. They come with the 

 great influx of warblers from the 10th to the 12th of May, and 

 are found building their nests from about the 20th to the end 

 of the first week in June, and sometimes bring out two broods. 

 The structure consists of dry leaves and fibrous barks, and is 

 lined with grass and hairs in addition to the fibres mentioned. 

 It is almost proverbially bulky, and placed in the forks of a 

 bush near the ground and usually contains from three to four 

 white eggs, variously speckled with reddish brown. They all 

 disappear during the last week in August.

SYLTANIl CANIDENSIS (L.). (686.) 



CANADIAN WARBLER. 



When this warbler first came under my notice, in 1875, I was 

 confident it was a straggler, but without any resource for 

 information as to the ultimate limits of its migratorial distri- 

 bution, I did not have to wait very long before his local history 

 began to unfold in fine style, for in a few weeks I bagged his 

 nest, companion, self, eggs and all. 



It reaches the lower limits of my province about May 15th, 

 and the larger portion of them pass still further north, never- 

 theless may remain and breed with us. The nest has been 

 found by Mr. Treganowan and Mr. Lewis, and reputedly by 

 some one else, and always on the ground. (The location has been 

 occasionally given from Audubon to date, as in low trees and 

 bushes). It consists of leaves, roots, and grasses, its lining 

 generally of the same with some hairs and considerable lichens 

 included. Although quite bulky, it is rather shallow, and 

 generally contains four gray- white eggs, tinted with a slight 

 blush of rose and spotted or blotched with lilac and brown 

 especially about the larger end.
