NESTS AND EGGS OF NORTH AMERICAN BIRDS. 29 



usually placed in a hemlock or spruce a few feet from the ground. It is a 

 light structure resembling that of the Chestnut-sided Warbler, composed 

 of twigs, weed-stalks and grasses, lined either with horse hair or fine 

 rootlets . 



Hab. Eastern Province of North America to Labrador, Hudson's Bay, Great Slave Lake, etc.; west to 

 Colorado. 



98. Cerulean Warbler — dendrceca CtERULEa. Dull creamy-white, 

 more or less thickly covered with blotches of reddish-brown; size .60 by 

 .47, The nests of this bird that have been described were all placed in 

 trees from twenty to fifty feet from the ground. They were constructed 

 with grasses and fibres of bark, lined with fine grass and more or less com- 

 pletely covered with lichen, bound on with spider's webs. 



Hab. Eastern United States, rarely north to New England, sometimes west to the Rocky Mts., in the 

 latitude of Colorado. 



99. Chestnut-sided Warbler — dendrceca pennsylvanica. Rich 

 creamy-white, and beautifully spotted, chiefly at the larger end, with pur- 

 ple and purplish-brown; four or five in number and average .68 by .50. 

 The nest is commonly built in a low bush, shrub, or sapling from two to 

 eight feet above the ground. The situations chosen are the "scrub-lands" 

 or open woods in low grounds which contain bushes, vines, etc. The nest 

 is generally coarser than the Yellow Warbler's and contains fewer woolly 

 materials. It is composed of narrow strips of thin bark or dried grasses, 

 mixed with plant down, fine bleached grasses and lined with hairs. Breeds 

 abundantly in the Middle and Northern States. 



Hab. Eastern United States and Canada; south to Panama, Bahamas. 



100. Bay-breasted Warbler — dendrgeca castanea. Bluish-green, 

 thickly spotted with brown, usually with a ring of blotches of brown and 

 lilac at the larger end; three to six in number and measure from .65 to .71 

 by .50 to .53. The nests are placed usually in a spruce or hemlock, fif- 

 teen or twenty feet from the ground ; they are said to be large for the size 

 of the bird and to resemble the nest of the Purple Finch. It is composed 

 of fine twigs, fibrous roots, moss, and lined with hair. This Warbler has 

 been found breeding only in the most northern United States and north- 

 ward. Hab. Eastern United States, north to Hudson Bay; south to Guatemala. 



101. Black-poll Warbler — dendrceca striata. White, spotted with 

 lavender, dark purple, lavender and reddish-brown ; three to five in num- 

 ber and measure .72 by .50. This bird is found in mixed woods, but has 

 a decided preference for evergreen forests. It passes far north to breed, 

 in Labrador and Arctic America; a few linger through the summer in 

 northern New England. The nests are usually placed in low, thick spruce 

 trees about eight feet from the ground. They are compactly built of
