306 NORTH AMERICAN BIRDS EGGS. 



684. Hooded Warbler. Wilsonia mitrata. 



Range. Eastern United States, breeding north to southern New England and 

 Michigan; winters south of our borders. 



This yellow and greenish species can be identified by its black 

 head, neck and throat, with the large yellow patch about the eye 

 and the forehead. The members of this genus are active fly- 

 catchers, darting into the air after passing insects in the manner 

 _ of the Flycatchers. They frequent tangled thickets where they 



[White 1 build their nests within a few inches of the ground, making them 

 of leaves, bark and grass, lined with hair; the four or five eggs 

 are white, specked with reddish brown and neutral tints; size .70 x .50. Data. 

 Doddridge Co., Mo., May 29, 1897. Nest one foot from the ground in a small 

 bush; made of leaves, strips of bark and fine grasses. Collector, K. B. Simp- 

 son. 



685. Wilson Warbler, Wilsonia pusilla. 



Range. Eastern North America, breeding from northern United States north- 

 ward; south to Central America in winter. 



These handsome little black-capped flycatching Warblers are 

 abundant during migrations, especially in the spring, being 

 found on the edges of woods and in orchards. They nest on the 

 ground, usually on the edges of swamps, embedding their nests 

 in the ground under the shelter of low branches or on the edges of [White 1 

 banks; the nest is of bark strips, fibres and leaves, and the eggs 

 are white, specked with reddish brown; size .60 x .50. 



685a. Pileolated Warbler. W. p. pileolata. 



Range. Western United States, breeding in the Rocky Mountain region from 

 Mexico to Alaska; winters south of the United States. 



Similar to the eastern form but the yellow underparts and greenish back are 

 brighter. Like the last species, this form nests on the ground or very close to it, 

 in weeds or rank undergrowth, in swamps. Their eggs which are laid in May 

 or June are not distinguishable from those of the last. 



685b. Golden Pileolated Warbler. W. p. chryseola, 



Range. Pacific coast of North America, breeding from southern California 

 in mountain ranges north to British Columbia. 



686. Canadian Warbler. Wilsonia canadensis. 



Range. Eastern North America, breeding from Mass., New York, and Michi- 

 gan north to Labrador and Hudson Bay; winters in Central America. 



This handsome Warbler is plain gray above and yellow below, 

 with a black stripe down the sides of the neck and across the 

 breast in a broken band. They frequent swamps or open woods 

 with a heavy growth of underbrush, where they build their nests 

 on or very close to the ground. I have always found them in 

 [White.] Massachusetts nesting about the roots of laurels, the nests being 

 made of strips of bark, leaves and grass; in June or the latter 

 part of May they lay from three to five white eggs, specked and wreathed with 

 reddish brown and neutral tints; size .68 x .50. Data. Worcester, Mass., June 

 10, 1891. Nest on the ground under laurel roots in swampy woods; made en- 

 tirely of strips of laurel bark lined with fine grass. Collector, C. A. Reed.
