GEN. CHAR. Size small. Head very large, without ear-tufts. Eyes moderate; iris yellow. Two outer primaries only with their inner webs distinctly emarginated. Tarsi and toes densely, but closely, feathered. Ear-conch very large, nearly as high as the skull, with an anterior operculum; the two ears exceedingly asymmetrical, not only externally, but in their osteological structure. Furcula not anchylosed posteriorly, but joined by a membrane.
Nyctale acadica.]
Of this genus only three species are as yet known; two of these belong to the Northern Hemisphere, one of them (N. tengmalmi) being circumpolar, the other (N. acadica) peculiar to North America. The habitat of the remaining species (N. harrisi) is unknown, but is supposed to be South America. If it be really from that portion of the New World, it was probably obtained in a mountainous region.

SP. CHAR. Adult (♀, 3,886, Montreal, Canada, September, 1853; Broome). Upper surface brownish-olive or umber-brown. Forehead and crown with numerous elliptical (longitudinal) marks of white, feathers everywhere with large partly concealed spots of the same; these spots are largest on the neck and scapulars, on the latter of a roundish form, the outer webs of those next the wing being almost wholly white, the edge only brown; on the nape the spots form V-shaped marks, the spots themselves being somewhat pointed; below this is a transverse, less distinct collar, of more concealed spots; wing-coverts toward the edge of the wing with a few large, nearly circular, white spots; secondaries with two transverse series of smaller white spots, these crossing about the middle, remote from the end and base; outer feathers of the alula with two white spots along the margin; primary coverts plain; primaries with four or five transverse series of white spots; tail with the same number of narrow transverse spots, forming incontinuous bands, the spots not touching the shaft,—the last spot not terminal. Facial circle much darker brown than the crown, and speckled with irregular spots of white, these either medial or upon only one web; across the throat the circle becomes paler brown, without the white spotting. Eyebrows and face grayish-white; lores and eyelids blackish. Lower parts white, becoming pale ochraceous on the legs; sides of the breast, sides, flanks, and lower tail-coverts with daubs of brown (slightly lighter and more reddish than on the back), those of the breast somewhat transverse, but posteriorly they are decidedly longitudinal; front of tarsus clouded with brown. Wing-formula, 3, 4–2–5–6–7–1. Wing, 7.20; tail, 4.50; culmen, .60; tarsus, 1.00; middle toe, .67.
A female from Alaska (49,802, Nulato, April 28, 1867; W. H. Dall) is considerably darker than the specimen described above; the occiput has numerous circular spots of white, and the tarsi are more thickly spotted; no other differences, however, are appreciable. Two specimens from Quebec (17,064 and 17,065; Wm. Cooper) are exactly similar to the last, but the numerous white spots on the forehead are circular.
HAB. Arctic America; in winter south into northern border of United States; Canada (DR. HALL); Wisconsin (DR. HOY); Oregon (J. K. TOWNSEND); Massachusetts (MAYNARD).
The Nyctale richardsoni, though, without doubt, specifically the same as the N. tengmalmi of Europe, is, nevertheless, to be distinguished from it. The colors of the European bird are very much paler; the legs are white, scarcely variegated, instead of ochraceous, thickly spotted; the lower tail-coverts have merely shaft-streaks of brown, instead of broad stripes. Very perfect specimens from Europe enable me to make a satisfactory comparison.
From an article by Mr. D. G. Elliot in Ibis (1872, p. 48), it would appear that the young of N. tengmalmi is very different from the adult in being darker and without spots; a stripe from the eye over the nostrils, and a patch under the eye at the base of bill, white. It is probable, therefore, that the American race has a similar plumage, which, however, has as yet escaped the honor of a name; more fortunate than the young of N. acadica, which boasts a similar plumage. This (N. albifrons) Mr. Elliot erroneously refers to the N. tengmalmi, judging from specimens examined by him from the Alps, from Russia, and from Norway. The most striking difference, judging from the description, apart from that of size, appears to be in the whiter bill of the tengmalmi.
HABITS. This race is an exclusively northern bird, peculiar to North America, and rarely met with in the limits of the United States. A few specimens only have been obtained in Massachusetts. Dr. Hoy mentions it as a bird of Wisconsin, and on the Pacific Dr. Townsend met with it as far south as Oregon, where it seems to be more abundant than on the eastern coast.
Mr. Boardman thinks that this Owl is probably a resident in the vicinity of Calais, where, however, it is not common. It was not taken by Professor Verrill at Norway, Maine. Mr. J. A. Allen regards it as a very rare winter visitant in Western Massachusetts, but obtained a specimen near Springfield in December, 1859. In the same winter another was shot near Boston, and one by Dr. Wood, near Hartford, Conn. Mr. Allen subsequently records the capture of a specimen in Lynn, Mass., by Mr. J. Southwick, in the winter of 1863, and mentions two other specimens, also taken within the limits of the State. It is not mentioned by Dr. Cooper as among the birds of California.
Specimens of this Owl were taken at Fort Simpson in May, and at Fort Resolution by Mr. B. R. Ross, at Big Island by Mr. J. Reid, at Fort Rae by Mr. L. Clarke, and at Fort Yukon by Mr. J. Lockhart and Mr. J. McDougall, and at Selkirk Settlement, in February and March, by Mr. Donald Gunn.
Mr. B. R. Ross states that though no specimens of this Owl were received from north of Fort Simpson, yet he is quite certain that it ranges to the Arctic Circle. He says it is a fierce bird, and creates great havoc among the flocks of Linnets and other small birds. Its nest is built on trees, and the eggs are three or four in number, of a pure white color and nearly round shape. It sometimes seizes on the deserted hole of a Woodpecker for a habitation.
Mr. Dall obtained a female specimen of this Owl at Nulato, April 28, where it was not uncommon. It was often heard crying in the evenings, almost like a human being, and was quite fearless. It could be readily taken in the hand without its making any attempt to fly away, but it had a habit of biting viciously. It was frequently seen in the daytime sitting on trees. According to the Indians, it generally nests in holes in dead trees, and lays six spherical white eggs. Richardson informs us that it inhabits all the wooded country from Great Slave Lake to the United States, and is very common on the banks of the Saskatchewan. It was obtained in Canada by the Countess of Dalhousie, but at what season the bird was met with is not stated; the Smithsonian Institution also possesses specimens from the vicinity of Montreal. It probably does not breed so far south as that place, or, if so, very rarely. Mr. Audubon procured a specimen near Bangor, Maine, in September, the only one he ever met with.
This Owl, according to Mr. Hutchins, builds a nest of grass half-way up a pine-tree, and lays two eggs in the month of May.
