      RARE ARCTIC BIRDS

      THE WHITE-HORNED OWL

      THE COCK OF THE PLAINS

      LEGS AND FEET OF THE MOUNTAIN GROUSE.

      Few of the results of recent expeditions of discovery have been so interesting to the public as their contributions to zoological history. Many important additions to geographical science have also been made by these journeys into countries hitherto unexplored, or but imperfectly known by Europeans; but the interest is not of that attractive character which is more or less attached to the natural history of these districts. The great delight that we take in the latter species of knowledge is referable to the curiosity we feel respecting the inhabitants of a country after we have once been assured of its existence. Our first inquiries naturally enough relate to the tenants of our own species; we then ask what description of quadrupeds are found over its plains, and how far they enlarge or circumscribe the enjoyments and liberty of sovereign man; the birds that warble in its groves, the insects that flutter in its breeze, the fish that tenant its seas, rivers, and lakes, and the plants that wave in wild luxuriance on its hills and dales; and by comparing all these varieties with the natural characteristics of our own country, and contrasting their differences with others, we are enabled, in some degree, to appreciate, by the linked gradations, the order and harmony that reign throughout nature—the minute beauty of parts which are so essential to the perfection of the grand whole.

      The last overland expedition to the Polar sea, under the command of Captain Sir John Franklin, was peculiarly fortunate in the collection of objects of natural history, which indeed were too numerous for the limits of an appendix, such as had appeared with the narratives of previous expeditions. Hence the number of the specimens warranted their publication in a separate form, under the able superintendance of Dr. Richardson, surgeon and naturalist to the expedition, aided by Mr. Swainson. The great expense of the requisite embellishment of the ornithological portion, however, threatened a formidable obstacle to its completeness; but this was met by a liberal grant of one thousand pounds by the British Government, to be applied solely towards the expense of the engravings—the present being the first zoological work ever published with the sterling assistance of His Majesty's Treasury. The first part of this truly great national work appeared some time since, with 28 spirited figures of Mammalia, from drawings by Landseer; the entomological and botanical parts are preparing for publication; and that of The Birds, (to which we are indebted for the annexed Cuts,) has very recently appeared.1

      Dr. Richardson, with zealous attachment to his pursuits, passed seven summers and five winters surrounded by the objects he has described with such fidelity. He is, therefore, not a mere book naturalist, but he has studied the habits and zoological details of the living animals; Mr. Swainson having assisted the Doctor in the systematic arrangement and production of the plates. Their descriptions include all the birds hitherto found over an immense expanse of country of the 49th parallel of latitude, and east of the Rocky Mountains, which lie much nearer to the Pacific Coast than to the eastern shore of America: many of these birds being, for the first time, made known to ornithologists. We have selected two of the most singular in their conformation: one from the Owls, which are numerous and beautiful; and the other from the Grouse, of which ten fine species are described.2

      THE ARCTIC, OR WHITE-HORNED OWL,

      Strix (Bubo) Arctica, SWAINSON.

      This very beautiful owl appears to be rare, only one specimen having been seen by the members of the Expedition. It was observed flying at mid-day in the immediate vicinity of Carlton House, and was brought down with an arrow by an Indian boy. Dr. Richardson could obtain no information respecting its habits.

      From Mr. Swainson's minute description we learn that the colour of the bill and claws is blueish black. The face is white, and a band of blackish-brown and white crosses the throat. The egrets or ear feathers are tipped with blackish-brown, the inner webs being white varied with wood-brown. The whole of the back is marked with undulated lines or fine bars of dark umber-brown, alternating with white: on the greater wing coverts the white is replaced by pale wood-brown. The primary and secondary feathers are wood-brown, margined inwards with white. They are crossed by umber-brown bars on both webs, the intervening spaces being finely speckled with the same. On the tertiary feathers, the wood-brown is mostly replaced by white. The tail-feathers are white, deeply tinged inwards by wood-brown, and crossed by bars of umber-brown; the tips are white. The chin is white. The throat is crossed by the band already mentioned, behind which there is a large space of pure snow white, that is bounded on the breast by blotches of liver-brown situated on the tips of the feathers. The belly and long plumage of the flanks are white, crossed by narrow bars of dark brown. The under tail coverts, thighs, and feet are pure white. The linings of the wings are pure white with the exception of a brown spot on the tips of the great interior coverts. The bill is strong, curved from the base, moderately compressed towards the tip, with a very obtuse ridge. The facial disk is small, and incomplete above the orbit. The egrets are more than two inches long, each composed of six or seven feathers, and situate behind the upper end of the black band bounding the face. The folded wings fall about three inches and a half short of the tail, which is rounded, the outer feathers being an inch shorter than the central ones. The plumage of the sides of the belly is long, and hangs down over the thighs. The thigh feathers are very downy, but are not long. The tarsi are rather long, and the toes are moderately long; they are clothed to the roots of the nails by a close coat of hairy feathers. The claws are strong, sharp, and very much curved.

      The length of the bird from the tip of the bill to the end of the tail is 21 inches 6 lines; and the length of the longest quill feather is 12 inches six lines.

      THE COCK OF THE PLAINS,

      Tetrao, 3 (Centrocercus,) Urophasianus,

      SWAINSON.

      This bird, which was first mentioned by Lewis and Clark,4 has since become well known to the fur traders that frequent the banks of the Colombia. Several specimens have been sent to England by the agents of the Hudson's Bay Company. Mr. David Douglas has published the following account of the manners of the species, the only one hitherto given.

      "The flight of these birds is slow, unsteady, and affords but little amusement to the sportsman. From the disproportionately small, convex, thin-quilled, wing,—so thin, that a vacant space, half as broad as a quill appears between each,—the flight may be said to be a sort of fluttering more than any thing else: the bird giving two or three claps of the wings in quick succession, at the same time hurriedly rising; then shooting or floating, swinging from side to side, gradually falling, and thus producing a clapping, whirring sound. When started, the voice is 'cuck, cuck, cuck,' like the common pheasant. They pair in March and April. The love-song is a confined, grating, but not offensively disagreeable, tone,—something that we can imitate, but have a difficulty in expressing—'Hurr-hurr—hurr-r-r-r hoo,' ending in a deep hollow tone, not unlike the sound produced by blowing into a large reed. Nest on the ground, under the shade of Purshia and Artemisia, or near streams, among Phalaris arundinacea, carefully constructed of dry grass, and slender twigs. Eggs from thirteen to seventeen, about the size of those of a common fowl, of a wood-brown colour, with irregular chocolate blotches on the thick end. The young leave the nest a few hours after they are hatched. In the summer and autumn months these birds are seen in small troops, and in winter and spring in flocks of several hundreds. Plentiful through the barren arid plains of the river Colombia; also in the interior of North California. They do not exist on the banks of the river Missouri; nor have they been seen in any place east of the Rocky Mountains."

      The general colour of the upper plumage is light hair-brown, mottled and variegated with dark umber-brown and yellowish-white. The under plumage is white and unspotted on the breast and
