BIRDS OF NEW MEXICO 
BLACK-POLL WARBLER: Dendroica striata (J. R. Forster) 
Description. — Male: Length (skins) 4.G-5.5 inches, wing 2.8-3, tail 1.9-2.1, 
bill .3-.4, tarsus .7-.8. Female: Length (skins) 4.5-5 inches, wing 2.7-2.9, tail 
1.8-2, bill .3-.4, tarsus .7-.8. Adult male in spring and summer: Crovm black , in 
striking contrast to white cheeks, rest of upperparts olive, gray, or brown, streaked 
with black; tail and wings dusky, tail with two or three outer pairs of feathers with 
white patches near tip; wings with two white bands and greenish edgings; underparts 
white, sides streaked with black. Adult male in fall and winter: Without black crown, 
upperparts olive-green shading to gray on upper tail coverts; back, scapulars, and 
sometimes crown and rump streaked with black; wing bars white, line over eye olive- 
yellowish; throat, breast, and sides yellowish; sides streaked; belly white. Adult 
female: Similar to adult male in fall and winter but grayer above, whiter below, the 
black streaks, from bill to rump, better defined. Young in juvenal plumage: Upper- 
parts grayish olive or olive-gray, with black, wedge-shaped shaft marks (except 
on rump), greater and middle wing coverts blackish; underparts whitish with 
rounded spots. 
Range. —Breeds in Hudsonian and Canadian Zones from limit of trees in north¬ 
western Alaska, northern Mackenzie, Keewatin, northern Quebec, and Newfound¬ 
land south to northern New England, Michigan, Manitoba, and northern British 
Columbia; winters in northern South America to Ecuador, Guiana, and eastern 
Brazil; migrates through Bahamas and West Indies; casual in Colorado, New 
Mexico, Mexico, Chile, and Ecuador. 
State Records. —The only record of the Black-poll Warbler in New Mexico is 
that by Doctor Henry, of “one or two only observed in April at the Miinbres.” 
The species is of course accidental in that part of the State, but since it migrates 
regularly in spring through Colorado east of the foothills, it undoubtedly also passes 
through northeastern New Mexico.—W. W. Cooke. 
Nest. —In conifers or on the ground, made of grasses, roots, lichen, and a few 
twigs, lined with fine grass and feathers. Eggs: 4 or 5, white, marked with brown, 
lilac, and gray, usually forming a wreath but sometimes marked all over. 
General Habits. —The Black-poll is one of the quiet, deliberate 
Warblers and one of the latest migrants. In speaking of its migration, 
Doctor Chapman says: “No Black-poll Warbler seems to spend the 
winter north of South America, while the southernmost breeding 
grounds are in northern New York and central Colorado. Therefore, 
no Black-poll Warbler can have a migration route less than twenty- 
five hundred miles in length, and the extremes of the range—Alaska 
and Brazil—are twice that distance apart . . . individuals that 
nest in Alaska travel at an average speed of not less than seventy- 
five miles per day” (1907, p. 197). 
BLACKBURNIAN WARBLER: Dendroica fusca (Muller) 
Description. — Male: Length (skins) 4.4-4.7 inches, wing 2.5-2.7, tail 1.8-1.9, 
bill .4, tarsus .6-.7. Female slightly smaller. Adult male in spring and summer: 
Crown stripe, superciliary , patch on side of neck , and anterior underparts intense orange 
or flame-color; rest of head, back, tail and wings black, back streaked with white, tail 
with two or three lateral feathers largely white, wings with conspicuous white patch 
on coverts; lower underparts white, more or less tinged with yellow, sides streaked 
with black. Adult female in spring: Like the male in color pattern but, colors dulled
