in the ads.; underparts white, tinged with cream-buff, especially on the flanks; 
ads. usually have some concealed chestnut in crown and traces of chestnut 
on sides. L., 5°63; W., 2°95; T., 2°12; B. from N., ‘30. 
Range.—E. N. Am. Breeds in Canadian zone from nw. Alberta, s. 
Keewatin, s. Ungava, and N. F. s. to s. Man., n. Maine, and mts. of N. H.; 
winters in Panama and Colombia; casual in migrations to Mont., 8. D., and 
Tex.; irregular on the Atlantic slope and rare s. of Va. 
Washington, sometimes abundant, usually uncommon T. V., May 2- 
27; Aug. 29-Nov. Ossining, tolerably common T. V., May 14-28; Aug. 5—

common T. V., May 4-23; Sept. 7-Oct. 10. Glen Ellyn, tolerably common 
T. V., May 8-June 5; Aug. 13-Oct. 4. SE. Minn., uncommon T. V., May 
13— ; Aug. 18-Sept. 15. 
Nest, of grasses and plant fibers, lined with plant-down and long hairs, 
in coniferous trees, 5~20 feet up. Eggs, 4-5, white, finely marked, chiefly at 
the larger end, distinctly and obscurely with cinnamon-, olive-, or rufous- 
brown, ‘72 x ‘52. Date, Bangor, Maine, June 15. 
During its migrations this tastefully marked Warbler is generally 
uncommon enough to be considered somewhat of a prize, though at 
irregular intervals it becomes comparatively common. It is said to be 
much rarer in fall than in spring, but at this season Bay-breasts so 
closely resemble Black-polls, that it is sometimes difficult to determine 
specimens, while, in immature plumage, many birds cannot possibly 
be distinguished in nature. 
In the summer the Bay-breasts inhabit the northern coniferous 
forests, living, it is said, in the tree tops. “In a grouping based on songs, 
the Bay-breast should stand in a quintette with the Blackburnian, the 
Black-poll, the Black and White, and the Cape May. . . . The Bay- 
breast’s singing, in the spring at least, is the most liquid and inarticulate 
of the lot and sometimes the loudest”’ (Thayer in ‘“Warblers of North 
America”).

661. Dendroica striata (Forst.). Buack-PoLL WaRBLER. (Fig. 123.) 
Ad. ¢.—Crown black; ear-coverts white; nape streaked, black and white; 
back and rump ashy, streaked with black; two white wing-bars; inner vanes 
of outer tail-feathers with white patches at their tips; underparts white, 
streaked with black, the streaks most numerous on the sides, and wanting 
on the middle of the breast and belly. Ad. ¢.—Upperparts olive-green, 
distinctly streaked with black; wings and tail as in the 7; underparts white, 
tinged with yellow, the breast and sides distinctly streaked with black. 
Ads, fall and im.—Similar to ¢, but the upperparts are brighter and not 
distinctly streaked, the underparts yellower and not distinctly streaked. 
L., 5°56; W., 2°92; T., 2°05; B. from N., °30. 
Remarks.—No two of our Warblers more closely resemble each other than 
do immature and fall examples of this and the preceding species. There is 
no difference in the color of the upperparts, but castanea has the underparts 
tinged with delicate cream-buff, strongest on the flanks, while striata is dis- 
tinctly yellowish below. 
Range.—N. A. Breeds in Hudsonian and Canadian zones from limit 
of trees in nw. Alaska, to N. F., s. to cen. B. C., Man., Mich., n. Maine, 
and mts. of Vt. and N. H.; winters from Venezuela to Brazil; migrates 
through the Bahamas and West Indies. (See Fig. 5.)
