This reiuark- al)lo owl, conspicuous both in size and color, inhabits the boreal regions of both continents, coming southward in winter ; it ordinarily enters the United States, and in extreme cases ranges irregularly through most of the States. It is not by any means exclusively nocturnal. WiLS., iv, 53, pi. 32, f. 1; Nutt., i, 116; AuD., i, 113, pi. 28; Cass, in Bd., 63; Coop., 447 kivea. 146. Genus SURTiTIA Dumeril. Hawh Old. Day Oid. Dark brown aljove, more or less thickly speckled with white ; below, closely barred with brown and whitish, the throat alone streaked; quills and tail with numerou with black. Length about 16 inches ; wing 9 ; tail 7, graduated, the lateral feathers 2 inches shorter than the central. Except in the Icngtli of its tail, which produces linear measurements unusual for a liird of its bulk in this family, its general form is that of the snowj' owl. Like that species, it is a ))ird of Arctic regions, coming southward in winter, but its range is more restricted, rarely extending to the Middle States. It is the most diurnal l>ird of the famil}', ranging abroad at all times, and approaches a hawk more nearly than any other. \Yils., vi, 64, pi. 50, f. 6; Nutt., i, 115; AuD., i, 112, pi. 27 ; Cass, in Bd., 64 ; Coop., 448. uliila var. ^ Fro. r:s.
