150 The Ottawa Naturalist. [November 



Black AND White Warbler. — June 5th, 1902. I saw a pair 

 which evidently had a nest near by. Not otherwise observed dur- 

 ing the breeding season though common about the loth of May. 



Blackburnian Warbler. — July (2th, 1902. I saw a pair in 

 an open spot of spruce woods, caused by surveyors felling several 

 trees whilst staking out a line. They were much disturbed by my 

 presence and probably had young. 



Canadian Warbler. — I saw a pair June 5th, 1902, and noticed 

 others at different times through summer months. 



Nashville Warbler. — June 12th, 1902. As lenergedfrom 

 spruce thicket into an alder grown portion of a blueberry swamp, 

 I noticed one of this species fly from a mossy knoll and after con- 

 siderable searching found the nest deeply embedded in the yielding 

 side of the mound. It was a slight affair (the surrounding mosses 

 rendering a more substantial structure unnecessary) of withered 

 grasses, moss and rootlets, containing four young a few days old. 

 I saw several others during the breeding season principally amongst 

 the undergrowth in boggy places. 



Magnolia Warbler. — One of the most common warblers in 

 this district, breeding in localities similar to those that the black- 

 throated green and myrtle frequent. A nest found June 5th, 1902, 

 was fastened, six feet from the ground and four from the trunk, 

 on to a well foliaged limb of a small shrubby spruce, situated on 

 the outskirts of a hilly spruce-grown pasture land, almost sur- 

 rounded with deep woods. The female was on the nest, which 

 was composed of very fine blackened grasses loosely fastened wifh 

 spiders' silk and lined with horsehairs, appearing very fragile and 

 transparent, somewhat similar to nests of the chipping sparrow. 

 It was well concealed by an overhanging branch and measured 

 inside depth lys, outside i^ inches; inside diameter 2, outside 

 31^ inches. The eggs, four in number, averaging .63 x .48 and 

 quite fresh, were washed on the larger ends with a pale shade of 

 cinnamon brown encircled with a wreath of spots of rusty brown 

 and lilac in varying shades, on a creamy white ground. On June 

 i6th another nest 2}4 feet from the ground resting on twigs of a 

 small cedar brush, the topmost foliage partially concealing it, was 

 composed of fine grasses, black rootlets and spruce twigs, loosely
