According to Mr. Audubon, this Owl breeds in hollow trees, or in the deserted nests of other birds; and lays from four to six glossy-white eggs, which are almost spherical. He states, also, that he found near Natchez a nest in the broken stump of a small decayed tree not more than four feet high. He also mentions the occasional occurrence of one of these Owls in the midst of one of our crowded cities. One of them was thus taken in Cincinnati, where it was found resting on the edge of a child’s cradle. Mr. McCulloch, quoted by Audubon, gives an interesting account of the notes and the ventriloquial powers of this bird. On one occasion he heard what seemed to him to be the faint notes of a distant bell. Upon approaching the place from which these sounds proceeded, they appeared at one time to be in front of him, then behind him, now on his right hand, now on his left, again at a great distance, and then close behind him. At last he discovered the bird at the entrance of a small hole in a birch-tree, where it was calling to its mate. As he stood at the foot of the tree, in full sight of the bird, he observed the singular power it possessed of altering its voice, making it seem near or remote,—a faculty which he had never noticed in any other bird.
An egg given me by Mr. Rufus E. Winslow as one of this bird, and figured in the North American Oölogy, was undoubtedly that of a Woodpecker. It is of a crystalline whiteness, nearly spherical, and measures 1.13 inches in length by .87 of an inch in breadth.
A well-identified egg in the collection of the Smithsonian Institution, taken by Mr. R. Christ at Nazareth, Penn., (No. 14,538, S. I.,) measures .95 of an inch by .88. The two ends are exactly similar or symmetrical. The egg is white, and is marked as having been collected April 25, 1867.
Genus SCOPS, Savigny
Scops, Savigny, 1809. (Type, Strix scops, L. = Scops zorca (Gm.) Swains.)
Ephialitis, Keys. & Bl. 1840, nec Schrank, 1802.
Megascops, Kaup, 1848. (Type, Strix asio, L.)
Gen. Char. Size small, the head provided with ear-tufts. Bill light-colored; iris yellow. Three to four outer quills with inner webs sinuated. Wings long (more than twice the length of the tail, which is short and slightly rounded); second to fifth quills longest. Toes naked, or only scantily feathered. Ear-conch small and simple. Plumage exceedingly variegated, the colors different shades of brown, with rufous, black, and white, in fine mottlings and pencillings; feathers above and below usually with blackish shaft-streaks, those beneath usually with five transverse bars; primaries spotted with whitish, and outer webs of the lower row of scapulars the same edged terminally with black. Tail obscurely banded.

Scops asio.
The species of this genus are cosmopolitan, the greater number, however, being found in tropical regions. All the American species differ from S. zorca of Europe in having the fourth and fifth quills longest, instead of the second, and in having three to four, instead of only two, of the outer quills with the inner web sinuated, as well as in having the quills shorter, broader, and more bowed, and their under surface more concave. They may, perhaps, be distinguished as a separate subgenus (Megascops, Kaup). Of the American species all but S. asio (including its several races) have the toes perfectly naked to their very bases.
Common Characters. Plumage brown, gray, or rufous, and whitish, finely mottled above; lower parts transversely barred, and with dark shaft-streaks. Outer webs of lower scapulars light-colored (white or ochraceous) and without markings. Tail crossed by rather obscure mottled light and dark bars of nearly equal width. Outer webs of primaries with nearly equal bands of whitish and dusky.
1. S. asio. Toes covered (more or less densely) with bristles, or hair-like feathers. Wing, 5.50–7.80; tail, 3.20–4.10; culmen, .50–.70; tarsus, 1.00–1.70; middle toe, .70–.80. Ear-tufts well developed; facial circle black.
Colors smoky-brown and pale fulvous, with little or none of pure white. Outer webs of the scapulars pale ochraceous-fulvous. Wing, 6.90–7.30; tail, 3.50–4.50. Hab. North Pacific region, from Western Idaho and Washington Territory, northward to Sitka … var. kennicotti.
Colors ashy-gray and pure white, with little or none of fulvous. Outer webs of the scapulars pure white. Varying to bright brick-red, or lateritious-rufous.
Mottlings coarse, the blackish median streaks above not sharply defined, and the bars beneath heavy and distinct.
Wing, 6.10–7.75; tail, 3.30–4.35. In the red plumage, white prevailing on the lower parts, where the red markings are not broken into transverse bars. Hab. United States; except the Southern Middle Province, the northwest region, and Florida … var. asio.
Wing, 5.50–6.00; tail, 2.75–3.10. In the red plumage, red prevailing on the lower parts, where the markings are much broken into transverse bars. Hab. Florida and Southern Georgia … var. floridanus.
Wing, 5.50–5.80; tail, 3.20–3.30. Gray plumage, like var. asio, but the mottling above much coarser, and the nape with a strongly indicated collar of rounded white spots in pairs, on opposite webs. Red plumage not seen. Hab. Eastern Mexico and Guatemala … var. enano.25
Mottlings fine, the blackish median streaks above very sharply defined and conspicuous; bars beneath delicate and indistinct.
Wing, 6.20–6.50; tail, 3.35–3.50. Hab. Southern Middle Province, and Southern California; Cape St. Lucas … var. maccalli.
2. S. flammeola. Toes perfectly naked, the feathering of the tarsus terminating abruptly at the lower joint. Wing, 5.40; tail, 2.80; culmen, .35; tarsus, .90; middle toe, .55. Ear-tufts short, or rudimentary. Facial circle rusty. Outer webs of the scapulars rusty-ochraceous, in striking contrast to the grayish of the wings and back. Other markings and colors much as in asio. Hab. Mountain regions of Mexico and California, from Guatemala to Fort Crook, Northern California.
