3. Vertex without any rufous. ♂. Anterior portions beneath deep ochraceous, without spots. Tail without indication of bars anterior to the subterminal one; black bars above confined to larger scapulars. ♀. Above ferruginous, with the black bars broader and blacker than in either of the preceding. Hab. Gulf, Caribbean, and Atlantic coasts of tropical continental America (Florida to Cayenne) … var. isabellinus.

4. Vertex with a patch of rufous. ♂. Black spots beneath numerous, large and circular. Tail with more or less complete black bars anterior to the subterminal band, sometimes regularly barred to the base; black bars above covering entire rufous surface. ♀. Similar to that of isabellinus, but markings beneath more numerous, and pure black instead of brown. Hab. Lesser Antilles, north to St. Thomas … var. dominicensis.[⁶⁵]

B. Tail tipped with deep rufous; outer tail-feather unvariegated.

5. Head above dark slaty-plumbeous, without any rufous. ♂. Tail continuous rufous to the extreme tip, the subterminal black band narrower than the terminal rufous one, and not continuous; the outer feather entirely rufous, without any black. In other respects much like var. australis. (♀ not seen.) Hab. Chile and Western Brazil … var. cinnamominus.[⁶⁶]

Sp. Char. Adult male (12,025, Washington, D. C.; W. Wallace). Forehead, lateral and posterior, regions of the vertex, occiput, and wings, bluish-ash. Vertex, nape, scapulars, interscapulars, rump, upper tail-coverts, and tail, fine cinnamon-rufous; scapulars and back barred with black, the bars broadest and most conspicuous posteriorly. Tail tipped with white, and with a broad sharply defined subterminal zone of black, about one inch in width; lateral feather, with outer web and terminal half of inner, ashy-white, the latter with one or two distinct transverse spots anterior to the subterminal one. Wing-coverts with more or less conspicuous cordate spots of black, rather sparsely distributed; basal two-thirds of secondaries and whole of primaries deep black; the latter whitish around the terminal margin and with nine transverse bands of white on inner web of longest (second), the white rather exceeding the black, the points of which do not reach the edge of the feather; lining of the wing white with conspicuous cordate spots of black. Front and superciliary region more hoary than the forehead, almost approaching white. Whole lateral region of the head, with chin, throat, and lower parts, white; the neck, breast, and sides, however, with a deep tinge of ochraceous, the tint hardly approaching the depth of color seen on the nape. On the head there are (considering both sides) seven black spots; the first originating in front of the bare anteorbital space (leaving the lores white), and extending in a stripe downward across the maxillæ, forming a conspicuous “mustache”; the second crosses the tips of the ear-coverts, in form of an oblong transverse spot; the third is smaller, situated as far behind the last as this, and is posterior to the “mustache,” crossing the side of the neck; the last is an odd nuchal spot separating the ash of the occiput from the rufous of the nape. Breast and sides with circular or cordate spots of pure black; these varying in size, but generally larger on the sides. Other lower parts immaculate. Wing-formula, 2=3–4, 1. Wing, 7.10; tail, 4.50; tarsus, 1.32; middle toe, .98; culmen, .45.

Adult female (10,751, Fort Bridger, Utah; C. Drexler). Blue above confined to the head, which shows the rufous patch as in the male; entire upper parts rufous, lighter and less purplish than in the male, everywhere barred with black. Tail with twelve sharply defined narrow bars of black; the subterminal broadest, and about three eighths of an inch in width. Longest primary with eleven transverse spaces of pale rufous, nearly twice as wide as the dusky ones, which scarcely touch the edge. Beneath yellowish-white, paler than in the male, breast and sides with rusty longitudinal spots. Head as in the male. Wing, 7.60; tail, 5.20; tarsus, 1.50; middle toe, .90; bill, .50. Wing-formula, 2=3–4–1.
