659. Chestnut-sided Warbler. Dendroira prnn.syivanica. 



Range. — United States, east of the Plains, breeding in the Middle States and 

 Illinois, north to Manitoba and New Brunswick. Winters south of our border. 



The adults of this handsome species may readily be known by 

 the white underparts and the broad chestnut stripe on the flanks; 

 the crown is yellow. They frequent low brush in open woods or 

 on hillsides and pastures, nesting at low elevations, usually be- 

 low three feet from the ground, and often concealing their nests 

 beneath the leaves in the tops of low small bushes. The nests 

 are made of grasses, weed stems and some fibres, but they do not 

 have as wooly an appearance as those of the Yellow Warblers which nest in the 

 same localities and similar locations. Their eggs are white or creamy white 

 (never greenish white), specked with brown and gray. Size .f)5 x .50. Data. — 

 Worcester, Mass., June 6, 1890. Nest in the top of a huckleberry bush, 2 feet 

 from the ground; made of grasses and plant fibres. Bird did not leave nest 

 until touched with the hand. Collector, A. J. White. 



660. Bay-breasted Warbler. Dcndrmca castaneu. 



Range. — North America, east of the Plains, breeding from northern United 

 States north to the Hudson Bay; winters in Central and South America. 



This species has the crown, throat and sides a rich chestnut; 



forehead and face black; underparts white. They nest in coni- 

 ferous trees in swampy places, making their nests of bark shreds 

 and rootlets and placing them in horizontal forks at elevations of 

 from five to thirty feet from the ground. The three or four eggs 

 are laid late in May or during June; they are white, usually quite 

 heavily spotted and blotched with reddish brown, umber and 

 grayish. Size .70 x .50. 



661. Black-poll Warbler. Dendroica striata. 



Range. — North America, east of the Rockies, breeding from northern United 

 States north to Labrador and Alaska; winters in South America. 



This black and white Warbler has a solid black cap, and the 

 underparts are white, streaked with black on the sides. In the 

 woods they bear some resemblance to the Black and White Warb- 

 ler, but do not have the creeping habits of that species. During 

 migrations they are found in equal abundance in swamps or 

 orchards. In their breeding range, they nest at low elevations [White.] 

 in stunted pines or spruces, making their nests of rootlets and lichens, lined 

 with feathers. The eggs are dull whitish, spotted or blotched with brown and 

 neutral tints. Size .72 x .50. Data. — Grand Manan, N. B., June 12, 1883. 

 Nest and four eggs on branch of a stunted spruce 2 feet from the ground. Col- 

 lector, S. F. Cheney. 



662. Blackburnian Warbler. Dendroica blackburnm'. 



Range. — North America, east of the Plains, breeding from Massachusetts and 

 Minnesota north to Hudson Bay; south in the Alleghanies to the Carolinas. 

 Winters in Central and South America. 



This species is, without exception, the most exquisite of tlie 

 family; the male can always be known by the bright orange 

 throat, breast and superciliary stripe, the upper parts being 

 largely black. They arrive with us when the apple trees are in 

 bloom and after a week's delay pass on to more northerly dis- 

 ((JreeiiishwhiteJ triets. Their nests are constructed of rootlets, fine weed stalks 

 and grasses, lined with hair, and are placed on horizontal limbs of coniferous 

 trees. The three or four eggs are greenish white, specked, spotted and blotched 

 with reddish brown and neutral tints. Size .70 x .48. Data. — Lancaster, Mass., 

 June 21, 1901. Nest in a white pine, 38 feet from the ground on a limb 4 feet 

 from the trunk; composed of fine rootlets and hair, resembling the nest of a 

 Chipping Sparrow. Collector, John E. Thayer.
