occupying most of the outer webs of the two or three lower feathers of the middle and secondary wing-coverts, white, forming (except on the first) conspicuous spots, those of the scapulars bordered with black. Secondaries crossed with about seven regular paler bands, each enclosing a more irregular dusky one; the ground-color, however, is so mottled with grayish, and the pale bands with dusky, that they are by no means sharply defined or conspicuous, though they are very regular; alula and primary coverts more sharply barred with cream-colored spots, those on the former nearly white; primaries with broad quadrate spots of creamy-white on outer webs, these forming from seven (♂) to eight (♀) transverse bands, the last of which is not terminal. Tail more irregularly mottled than the wings, and crossed by seven (♂) to eight (♀) narrow, obsolete, but continuous, pale bands.
Eyebrows white, the feathers bordered with dusky (most broadly so in ♂); cheeks, ear-coverts, and lower throat dull white, with transverse bars of blackish (most numerous in the ♂); chin immaculate; upper eyelid dark brown; facial circle black; neck and jugulum like the cheeks, but more strongly barred, and with blackish along the shaft. Ground-color of the lower parts white, each feather with a medial stripe of black, this throwing off distinct bars to the edge of the feather; the medial black is largest on sides of the breast, where it expands into very large conspicuous spots, having a slight rusty exterior suffusion; the abdomen medially, the anal region, and the lower tail-coverts, are almost unvaried white. Tibiæ and tarsi in the male dull white, much barred transversely with blackish; in the female, pale ochraceous, more sparsely barred with dark brownish. Lining of the wing creamy-white, varied only along the edge; light bars on under surface of primaries very obsolete.
♂ (16,027, Fort Crook, North California; John Feilner). Wing, 6.70; tail, 3.80; culmen, .61; tarsus, 1.35; middle toe, .72; ear-tufts, 1.00; wing-formula, 3=4, 5–2, 6, 1=9. “Length, 9.50; extent, 23.75.”
♀ (18,299, Hellgate, Montana; Jno. Pearsall). Wing, 7.80; tail, 4.10; culmen, .70; tarsus, 1.70; middle toe, .80; ear-tufts, 1.00.
Young ♂ (No. 29,738, Wood’s Hole, Mass., July 25, 1863; S. F. Baird. “Parent gray”). Secondaries, primaries, and tail, as in the adult, gray plumage; but the latter more mottled, the bands confused. Rest of the plumage everywhere grayish-white, with numerous transverse bars of dusky-brown; eyebrows and lores scarcely variegated dull white; facial circle obsolete.
♀ (41,891, Philadelphia, Penn.; J. Krider). Whole head, neck, back, rump, and entire lower parts transversely barred with dark brown and grayish-white, the bands of the former on the upper parts rather exceeding the white in width, but on the lower surface much narrower; scapulars with large transverse spots of white on the outer webs. Wings and tail as in the adult. Facial disk conspicuous. (More advanced in age than the preceding.)
Adult. General pattern of the preceding; but the grayish tints replaced by lateritious-rufous, very fine and bright, with a slight vinaceous cast: this is uniform, and shows no trace of the transverse dark mottling; there are, however, black shaft-lines to the feathers (these most conspicuous on the head above, and scapulars, and narrower and more sharply defined than in the gray plumage). The inner webs of the ear-tufts, outer webs of scapulars, and lower secondary and middle wing-coverts, are white, as in the gray plumage; those of the scapulars are also bordered with black. The secondaries, primaries, and tail are less bright rufous than the other portions, the markings as in the gray plumage, only the tints being different. The upper eyelid, and, in fact, all round the eye, fine light rufous; cheeks and ear-coverts paler, scarcely variegated; black facial circle rather narrower than in the gray plumage. Lower parts without the transverse bars of the gray plumage, but in their place an irregular clouding of fine light red, like the back; the lower parts medially (very broadly) immaculate snowy-white; most of the feathers having the red spotting show black shaft-stripes, but the pectoral spots are not near so large or conspicuous as in the gray bird. Tibiæ fine pale ochraceous-rufous; tarsi the same posteriorly, in front white with cuneate specks of rufous; lower tail-coverts each with a medial transversely cordate spot of dilute rufous, the shaft black. Lining of the wing with numerous rufous spots.
♂ (12,045, Washington, D. C., January). Wing, 6.30; tail, 3.00.
♀ (22,512, Maryland; R. G. Campbell). Wing, 6.70; tail, 3.50.
Young (29,792, Peoria, Illinois; Ferd. Bischoff). Wings and tail as in adult; markings on head and body as in the young gray bird, but white bars more reddish, and dark ones more brown.
Hab. Temperate North America, from the South Atlantic States to Oregon, and from the northern United States to Texas. Replaced in the southern Middle Province and Southern California by var. maccalli, in Florida by var. floridana, and on the northwestern coast region by var. kennicotti.
Localities: (?) Cuba (Cabanis, Journ. III, 465).
The above stages of plumage have caused ornithologists a great deal of perplexity; and it is only very recently that they have become correctly understood. Even yet many persist in regarding the red plumage as being that of the young bird.
Scops asio.
That these two very different plumages are entirely independent of age, sex, or season, and that they are purely individual, there can be no doubt; since in one nest there may often be found both red and gray young ones, while their parents may be either both red or both gray, the male red and the female gray, or vice versa. Occasionally specimens (such as No. 39,093, ♂, Neosho Falls, Kansas, April 13; parent of five eggs, and captured on the nest with a gray male) are exactly intermediate between these two plumages, it being difficult to decide which predominates; the combination is not only of the tints, but of the markings, of the two stages.
Habits. The habit of all the varieties of Scops asio in their different localities will be found after their zoölogical description.
Scops asio, Allen, Bull. Mus. Comp. Zoöl. and other citations from Florida.
Char. Similar to var. asio, but much smaller, and the colors deeper. The gray stage very similar to that of var. asio, but the red phase very appreciably different, in there being a greater amount of rufous on the lower parts, the breast being nearly uniformly colored, and the rufous broken elsewhere into transverse broad bars, connected along the shaft. Wing, 5.50–6.00; tail, 2.75–3.10.
Hab. Florida and Lower Georgia.
This extreme southern form is much smaller than the more northern ones, being about the same in size as the var. enano (see p. 1374) of Middle America, and the S. atricapilla, Temm., of Tropical America generally. The colors, as may be expected, are also darker and richer.
In the collection of the Smithsonian Institution there are both red and gray birds from Florida; a red one (No. 5,857, Indian River; Dr. A. W. Wall) measures, wing, 5.50; tail, 2.70; culmen, .55; tarsus, 1.05; middle toe, .65; ear-tufts, .70. The colors are much darker than those of typical asio. The rufous of the neck, all around, shows obsolete darker transverse bars; the black border to the white scapular spots is restricted to the tip, as in the gray plumage; the inner webs of the ear-tufts are scarcely paler than the outer; the neck and face are deeper rufous, while the rufous of the lower parts is more general, and more in transverse rays; tibiæ and tarsi plain rufous; the middle of the abdomen and the anal region only are pure white.
