Syrnium nebulosum.

Subgenera

Scotiaptex. Six outer quills with their inner webs emarginated. Toes completely concealed by dense long hair-like feathers. Iris yellow. (Type, S. cinereum.)

Syrnium, Swainson. Five outer quills with their inner webs emarginated. Toes not completely concealed by feathers; sometimes nearly naked; terminal scutellæ always (?) exposed. Iris blackish. (Type, S. aluco.)

The typical species of this genus are confined to the Northern Hemisphere. It is yet doubtful whether the Tropical American species usually referred to this genus really belong here. The genera Ciccaba, Wagl., and Pulsatrix, Kaup, have been instituted to include most of them; but whether these are generically or only subgenerically distinct from the typical species of Syrnium remains to be decided.

Our S. nebulosum and S. occidentale seem to be strictly congeneric with the S. aluca, the type of the subgenus Syrnium, since they agree in the minutest particulars in regard to their external form, and other characters not specific.

Syrnium lapponicum, var. cinereum, Coues, Key, 1872, 204. Strix acclamator, Bart. Trans. 285, 1792.

Sp. Char. Adult. Ground-color of the upper surface dark vandyke-brown, but this relieved by a transverse mottling (on the edges of the feathers) of white, the medial portions of the feathers being scarcely variegated, causing an appearance of obsolete longitudinal dark stripes, these most conspicuous on the scapulars and back. The anterior portions above are more regularly barred transversely; the white bars interrupted, however, by the brown medial stripe. On the rump and upper tail-coverts the mottling is more profuse, causing a grayish appearance. On the wing-coverts the outer webs are most variegated by the white mottling. The alula and primary coverts have very obsolete bands of paler; the secondaries are crossed by nine (last terminal, and three concealed by coverts) bands of pale grayish-brown, inclining to white at the borders of the spots; primaries crossed by nine transverse series of quadrate spots of mottled pale brownish-gray on the outer webs, those beyond the emargination obscure,—the terminal crescentic bar distinct, however; upper secondaries and middle tail-feathers with coarse transverse mottling, almost forming bars. Tail with about nine paler bands, these merely marked off by parallel, nearly white bars, enclosing a plain grayish-brown, sometimes slightly mottled space, just perceptibly darker than the ground-color; basally the feathers become profusely mottled, so that the bands are confused; the last band is terminal. Beneath with the ground-color grayish-white, each feather of the neck, breast, and abdomen with a broad, longitudinal ragged stripe of dark brown, like the ground-color of the upper parts; sides, flanks, crissum, and lower tail-coverts with regular transverse narrow bands; legs with finer, more irregular, transverse bars of dusky. “Eyebrows,” lores, and chin grayish-white, a dusky space at anterior angle of the eye; face grayish-white, with distinct concentric semicircles of blackish-brown; facial circle dark brown, becoming white across the foreneck, where it is divided medially by a spot of brownish-black, covering the throat.

♂ (32,306, Moose Factory, Hudson Bay Territory; J. McKenzie). Wing-formula, 4=5, 3, 6–2, 7–8–9, 1. Wing, 16.00; tail, 11.00; culmen, 1.00; tarsus, 2.30; middle toe, 1.50.

♀ (54,358, Nulato, R. Am., April 11, 1868; W. H. Dall). Wing-formula, 4=5, 3, 6–2, 7–8–9, 1. Wing, 18.00; tail, 12.50; culmen, 1.00; tarsus, 2.20; middle toe, 1.70.

Hab. Arctic America (resident in Canada?). In winter extending into northern borders of United States (Massachusetts, Maynard).

The relationship between the Syrnium cinereum and the S. lapponicum is exactly parallel to that between the Otus vulgaris, var. wilsonianus, and var. vulgaris, Surnia ulula, var. hudsonia, and the var. ulula, and Nyctale tengmalmi, var. richardsoni, and the var. tengmalmi. In conformity to the general rule among the species which belong to the two continents, the American race of the present bird is very decidedly darker than the European one, which has the whitish mottling much more prevalent, giving the plumage a lighter and more grayish aspect. The white predominates on the outer webs of the scapulars. On the head and neck the white equals the dusky in extent, while on the lower parts it largely prevails. The longitudinal stripes of the dorsal region are much more conspicuous in lapponicum than in cinereum.

Syrnium cinereum.

A specimen in the Schlütter collection, labelled as from “Nord-Europa,” is not distinguishable from North American examples, and is so very unlike the usual Lapland style that we doubt its being a European specimen at all.

Habits. The Great Gray or Cinereous Owl appears to be confined to the more northern portions of North America. It is rarely met with in any part of the United States, and only in winter, with the exception of Washington Territory, where it is presumed to be a resident. It is also said to be a resident in Canada, and to be found in the vicinity of Montreal. Mr. Lawrence does not include this bird in his list of the birds of New York, but Mr. Turnbull states that several have been taken as far south as New Jersey. Throughout New England it is occasional in the winter, but comparatively rare. Mr. Allen did not hear of any having been taken near Springfield. On the coast of Massachusetts they are of infrequent occurrence, and are held at high prices. A fine specimen was shot in Lynn in the winter of 1872, and is now in the collection of my nephew, W. S. Brewer. On the Pacific coast it is resident as far south as the mouth of the Columbia, and is found in winter in Northern California.

Dr. Richardson met with this Owl in the fur regions, where it seemed to be by no means rare. He mentions it as an inhabitant of all the wooded districts which lie between Lake Superior and latitude 67° and 68°, and between Hudson’s Bay and the Pacific. It was common on the borders of Great Bear Lake, in which region, as well as in a higher parallel of latitude, it pursues its prey during the summer months by daylight. It was observed to keep constantly within the woods, and was not seen to frequent the barren grounds, in the manner of the Snowy Owl, nor was it so often met with in broad daylight as the Hawk Owl, apparently preferring to hunt when the sun was low and the recesses of the woods deeply shadowed, when the hares and other smaller quadrupeds, upon which it chiefly feeds, were most abundant.

On the 23d of May, Dr. Richardson discovered a nest of this Owl, built on the top of a lofty balsam-poplar, composed of sticks, with a lining of feathers. It contained three young birds, covered with a whitish down, to secure which it was necessary to cut down the tree. While this was going on, the parent birds flew in circles around the tree, keeping out of gun-shot, and apparently undisturbed by the light. The young birds were kept alive for several weeks, but finally escaped. They had the habit, when any one entered the room in which they were kept, of throwing themselves back and making a loud snapping noise with their bills.

In February, 1831, as Audubon was informed, a fine specimen of one of these Owls was taken alive in Marblehead, Mass., having been seen perched upon a woodpile early in the morning. It was obtained by Mr. Ives, of Salem, by whom it was kept several months. It was fed on fish and small birds, and ate its food readily. It would at times utter a tremulous cry, not unlike that of the common Screech-Owl (Scops asio), and manifested the greatest antipathy to cats and dogs.

Dr. Cooper found this bird near the mouth of the Columbia River, in a brackish meadow partially covered with small spruce-trees, where they sat concealed during the day, or made short flights from one to another. Dr. Cooper procured a specimen there in June, and has no doubt that the bird is resident and breeds in that neighborhood. He regards it as somewhat diurnal in its habits, and states that it is especially active toward sunset.

Dr. Newberry speaks of this Owl as one generally distributed over the western part of the continent, he having met with it in the Sacramento Valley, in the Cascade Mountains, in the Des Chutes Basin, and in Oregon, on the Columbia River. Mr. Robert MacFarlane found it in great abundance in the Anderson River region. On the 19th of July, as we find in one of his memoranda, he met with a nest of this species near Lockhart River, on the route to Fort Good Hope. The nest was on the top of a pine-tree, twenty feet from the ground. It contained two eggs and two young, both of which were dead. The nest was composed of sticks and mosses, and was lined thinly with down. The female was sitting on the nest, but left it at his approach, and flew to a tree at some distance, where she was shot.

Mr. Donald Gunn writes that the Cinereous Owl is to be found both in summer and in winter throughout all the country commonly known as the Hudson Bay Territory. He states that it hunts by night, preys upon rabbits and mice, and nests in tall poplar-trees, usually quite early in the season.

A single specimen of this Owl was taken at Sitka by Bischoff, and on the 20th of April Mr. Dall obtained a female that had been shot at Takitesky, about twenty miles east of the Yukon, near Nulato. He subsequently obtained several specimens in that region. Mr. Dall describes it as very stupid, and easy to be caught by the hand during the daytime. From its awkward motions its Indian name of nūhl-tūhl, signifying “heavy walker,” is derived. So far as observed by Mr. Dall, this Owl appeared to feed principally upon small birds, and he took no less than thirteen crania and other remains of Ægiothus linaria from the crop of a single bird.

Specimens of this Owl have also been received by the Smithsonian Institution, collected by Mr. Kennicott, from Fort Yukon and from Nulato; from Mr. J. McKenzie, Moose Factory; from J. Lockhart, obtained at Fort Resolution and at Fort Yukon; from J. Flett, at La Pierre House; from B. R. Ross, at Big Island; and from Mr. S. Jones and Mr. J. McDougall, at Fort Yukon. These were all taken between February 11 and July 19.

One of the eggs of this Owl, referred to above in Mr. MacFarlane’s note, is in my cabinet. It is small for the size of the bird, and is of a dull soiled-white color, oblong in shape, and decidedly more pointed at one end than at the other. It measures 2.25 inches in length by 1.78 in breadth. The drawing of an egg of this species, made by Mr. Audubon from a supposed specimen of an egg of this species, referred to in the “North American Oölogy,” and which measured 2.44 by 2.00 inches, was probably a sketch of the egg of the Snowy Owl.

Sp. Char. Adult. Head, neck, breast, back, scapulars, and rump with broad regular transverse bars of ochraceous-white and deep umber-brown, the latter color always terminal; on the upper surface the brown somewhat exceeds the whitish in width, but on the neck and breast the white rather predominates. The lower third of the breast is somewhat differently marked from the upper portion, the brown bars being connected along the shaft of the feather, throwing the white into pairs of spots on opposite webs. Each feather of the abdomen, sides, flanks, and lower tail-coverts has a broad medial longitudinal stripe of brown somewhat deeper in tint than the transverse bars on the upper parts; the anal region is plain, more ochraceous, white; the legs have numerous, but rather faint, transverse spots of brown. Ground-color of the wings and tail brown, like the bars of the back; middle and secondary wing-coverts with roundish transverse spots of nearly pure white on lower webs; lesser coverts plain rich brown; secondaries crossed by six bands of pale grayish-brown, passing into paler on the edge of each feather,—the last is terminal, passing narrowly into whitish; primary coverts with four bands of darker ochraceous-brown; primaries with transverse series of quadrate pale-brown spots on the outer webs (growing deeper in tint on inner quills), the last terminal; on the longest are about eight. Tail like the wings, crossed with six or seven sharply defined bands of pale brown, the last terminal.

Face grayish-white, with concentric semicircular bars of brown; eyebrows and lores with black shafts; a narrow crescent of black against anterior angle of the eye. Facial circle of blackish-brown and creamy-white bars, the former prevailing along the anterior edge, the latter more distinct posteriorly, and prevailing across the neck in front, where the brown forms disconnected transverse spots.

♀ (752, Carlisle, Penn.). Wing-formula, 4–3, 5–2, 6; 1=9. Wing, 13.00; tail, 9.00; culmen, 1.05; tarsus, 1.90; middle toe, 1.50.

♂. A little smaller. (No specimen marked ♂ in the collection.)

Hab. Eastern North America, west to the Missouri; Rio Grande region.

A female (?) from Calais, Me., (4,966; G. A. Boardman,) is somewhat lighter-colored than the type, owing to the clearer white of the bars. It measures, wing, 13.50; tail, 9.80.

A specimen (4,357, January) from Washington, D. C., is quite remarkable for the very dark tints of plumage and the unusual prevalence of the brown; this is of a more reddish cast than in all other specimens, becoming somewhat blackish on the head and neck; anteriorly it prevails so as to almost completely hide the pale bars of the back and nape. The tail has no bars except three or four very obsolete ones near the end; beneath, the ochraceous tinge is quite deep. The toes, except their first joint, are perfectly naked; the middle one, however, has a narrow strip of feathering running along the outer side as far as the last joint. The darker shades of color, and more naked toes, seem to be distinguishing features of southern examples.

Syrnium nebulosum.

Habits. The Barred Owl has an extended range, having been met with nearly throughout North America, from about latitude 50° to Texas. Minnesota is the most western point to which, so far as I am aware, it has been traced. It is more abundant in the Southern States than elsewhere, and in the more northern portions of North America is somewhat rare. Richardson did not encounter it in the more arctic portion of the fur countries, nor has it, so far as I can learn, been observed on the Pacific coast. It is said to be of accidental occurrence in northern Europe.

In Louisiana, as Mr. Audubon states, it is more abundant than anywhere else; and Dr. Woodhouse speaks of it as very common in the Indian Territories, and also in Texas and New Mexico, especially in the timbered lands bordering the streams and ponds of that region. In July, 1846, while in pursuit of shore birds in the island of Muskeget, near Nantucket, in the middle of a bright day, I was surprised by meeting one of these birds, which, uninvited, joined us in the hunt, and when shot proved to be a fine male adult specimen.

The Barred Owl was found in great abundance in Florida by Mr. J. A. Allen, the only species of Owl at all common, and where its ludicrous notes were heard at night everywhere, and even occasionally in the daytime. At night they not unfrequently startle the traveller by their strange utterances from the trees directly over his head.

Mr. Dresser speaks of it as very abundant at all seasons of the year in the wooded parts of Texas. He was not able to find its nest, but was told by the hunters that they build in hollow trees, near the banks of the rivers.

According to Mr. Downes, this Owl is common throughout Nova Scotia, where it is resident, and never leaves its particular neighborhood. It breeds in the woods throughout all parts of that colony, and was observed by him to feed on hares, spruce and ruffed grouse, and other birds. It is said to be a quite common event for this bird to make its appearance at midnight about the camp-fires of the moose-hunter and the lumberer, and to disturb their slumbers with its cries, as with a demoniacal expression it peers into the glare of the embers. Distending its throat and pushing its head forward, it gives utterance to unearthly sounds that to the superstitious are quite appalling.

Mr. Wilson regarded this species as one of the most common of the Owls in the lower parts of Pennsylvania, where it was particularly numerous in winter, among the woods that border the extensive meadows of the Schuylkill and the Delaware River. He frequently observed it flying during the day, when it seemed to be able to see quite distinctly. He met with more than forty of these birds in one spring, either flying or sitting exposed in the daytime, and once discovered one of its nests situated in the crotch of a white oak, among thick foliage, and containing three young. It was rudely put together, made outwardly of sticks, intermixed with dry grasses and leaves, and lined with smaller twigs. He adds that this Owl screams in the day in the manner of a Hawk. Nuttall characterizes their peculiar hooting as a loud guttural call, which he expresses by ’koh-’koh-’ko-’ko-’ho, or as ’whah-’whah-’whah-’whah-aa, heard occasionally both by day and by night. It is a note of recognition, and may be easily imitated, and can be used as a means to decoy the birds. Nuttall received a specimen that had been shot in November, hovering, in the daytime, over a covey of Quail.

Mr. Audubon speaks of the peculiar hooting cries of this species as strangely ludicrous in sound, and as suggestive of an affected burst of laughter. He adds that he has frequently seen this nocturnal marauder alight within a few yards of his camp-fire, exposing its whole body to the glare of the light, and eying him in a very curious manner, and with a noticeable liveliness and oddness of motion. In Louisiana, where he found them more abundant than anywhere else, Mr. Audubon states that, should the weather be lowering, and indicative of the approach of rain, their cries are so multiplied during the day, and especially in the evening, and they respond to each other in tones so strange, that one might imagine some extraordinary fête was about to take place among them. At this time their gesticulations are said to be of a very extraordinary nature.

The flight of this Owl is described as remarkably smooth, light, noiseless, and capable of being greatly protracted. So very lightly do they fly, that Mr. Audubon states he has frequently discovered one passing over him, and only a few yards distant, by first seeing its shadow on the ground, in the bright moonlight, when not the faintest rustling of its wings could be heard.

This Owl has the reputation of being very destructive to poultry, especially to half-grown chickens. In Louisiana they are said to nest in March, laying their eggs about the middle of the month. Audubon states that they nest in hollow trees on the dust of the decomposed wood, and at other times take possession of the deserted nest of a crow, or of a Red-tailed Hawk. In New England I think they construct their own nest. Mr. William Street, of Easthampton, Mass., has twice found the nest of this Owl. On one occasion it had young, unfledged. Upon returning to get them, a few days later, they had disappeared, and as he conjectures, had been removed by their parents. Another time he found a nest in a lofty pine, and at a height of sixty feet. He saw and shot the old bird. He has often found them hiding themselves by day in a thick hemlock. In the winter of 1869, Mr. Street witnessed a singular contest between a Barred Owl and a Goshawk over a Grouse which the latter had killed, but of which the Owl contested the possession. The Hawk had decidedly the advantage in the fight, when the contest was arrested by shooting the Owl. He has noticed a pair of Barred Owls in his neighborhood for the past four years, and has never known them to hoot from the time they have reared their young to the 14th of February. They then begin about an hour after dark, and their hooting continues to increase until about the 8th of April, when they mate, at which time their hooting may be heard both day and night. There is a very great difference observable between the cries of the female and the utterances of the male. The latter seldom hoots, and there is as much difference between his voice and that of the female as between the crowing of a young bird and of the old cock.

In two instances I have known well-developed eggs of this Owl taken from the oviduct of the female in February. One of these cases occurred near Niagara Falls in the spring of 1852. The other, in 1854, was noticed by Professor William Hopkins, then of Auburn, N. Y., to whose kindness I was indebted for the egg the parentage of which is so unquestionable. It is purely white, almost globular, and, except in shape, hardly distinguishable from the egg of the domestic Hen. It is 2.00 inches in length, and 1.69 in breadth.

Syrnium occidentale, Xantus

WESTERN BARRED OWL; SPOTTED OWL

Syrnium occidentale, Xantus, P. A. N. S. Philad. 1859, 193.—Baird, Birds N. Am. App. pl. lxvi.—Coues, Key, 1872, 204.

Sp. Char. Adult (♂, 17,200, Fort Tejon, California; J. Xantus. Type of Xantus’s description). Above deep umber-brown, much as in S. nebulosum. Whole head and neck with circular and cordate spots of white, one near the end of each feather; on the scapulars and back, rump, wings, and tail, they are rather sparse and more transverse, but of very irregular form; they are most conspicuous on the scapulars and larger wing-coverts. Secondaries crossed with about six bands of paler brown, each spot growing white on the edge of the feather,—the last band terminal; primaries with seven transverse series of pale brown, or brownish-white, quadrate spots on outer webs, the last terminal; these spots are almost clear white on the third, fourth, fifth, and sixth quills. Tail with about eight very narrow, rather obsolete, bands of pale brown, growing whiter and more distinct terminally, the last forming a conspicuous terminal band. Ground-color of the lower parts dull white, somewhat tinged with ochraceous laterally; everywhere with numerous transverse spots and bars of brown like the back,—this predominating anteriorly, the white forming spots on opposite webs; on the lower tail-coverts the transverse spots or bars are very sharply defined and regular, the brown rather exceeding the white. Face, eyebrows, and lores soiled brownish-white, the former with obscure concentric semicircles of darker brownish. Facial circle blackish-brown, spotted posteriorly with white; across the neck in front, it is more broken. Legs white, with sparse obsolete transverse specks. Wing-formula, 4, 3, 5–6–2; 1=9. Wing, 13.10; tail, 9.00; culmen, .85; tarsus, 2.10; middle toe, 1.30. Length, “18”; extent, “40.”
