Wing, 13.16- 15.80; tail, 7.90- 11.00; culmen, 1.00- 1.10; tarsus, 3.00- 3.50; middle toe, 1.60- 1.80. Third and fifth quills longest, the first intermediate between the eighth and tenth; outer four with the inuer webs slightly sinuated. Tail very slightly rounded, the outer pair of feathers just appreciably the shortest. Upperta% Lcov& rt8black, barred with white. Adult:- General color uniform black, with a strong glaucous cast on the back, neck, and breast; upper tail- coverts narrowly tipped with white; tail deep black, narrowly tipped with white, white at the extreme base and crossed at about the middle by a broad, continuous zone of the same, of variable width. Inner webs and the concealed portion of the outer webs of the secondaries usually ( but not always) mottled with rusty ochraceous; terminal half of the bill plumbeous- black; the basal half, the cere, and the rictus yellow; tarsi and toes yellow; claws plumbeous- black. Young:- Above brownish- black, more or less variegated with ochraceous and sometimes with rusty on wing- coverts and scapulars ; wings indistinctly banded with dark grayish- brown ; head, neck, and lower parts ochraceous- wbite, with longitudinal stripes of black; tibia* transversely barred with the same; tail crossed with about seven bands of black and white, the bands of each individual feather oblique; the relative width of the two colors varying with the individual, but the subterminal black baud always about twice as broad as the others. Inner webs of secondaries strongly tinged with rufous. Upper tail-cqyerts white, more or less barred with black. On the head and neck, the streaking is not uniform, but the areas where the light or dark markings predominate respectively are as follows: the gular region, cheeks, and supraoral region are whitish, with fine streaks; but the pileum and nape, upper half of the auriculars, and maxillary stripe extending across the jugulum are nearly uniformly black, in consequence of the enlargement and blending of the streaks. " Iris brown; cere and base of bill olive- yellow or greenish; feet yellow." The white tail- bands vary considerably in width with the specimen ; but we cannot discover any rule of difference according to locality or |
