Strix Flammea, Linn. Not a single individual of the numerous persons who have described the birds of the United States, seems to have had opportunities of studying the habits of this beautiful Owl, and all that I find related respecting it is completely at variance with my observations. In describing the manners of this bird, I shall therefore use all due caution, although at the same time I shall not be too anxious to obtain credit in this, more than in some other matters, for which I have patiently borne the contradictions of the ignorant. The following extracts from my journals I hope will prove interesting. St Augustine, East Florida, 8th November 1832.—Mr Simmons, the Keeper of the Fort, whom I had known at Henderson in Kentucky, having informed me that some boys had taken five young Barn Owls from a hole in one of the chimneys, I went with a ladder to see if I could procure some more. After much search I found only a single egg, which had been recently laid. It was placed on the bare stone of the wall, surrounded by fragments of small quadrupeds of various kinds. During our search I found a great number of the disgorged pellets of the Owl, among which some were almost fresh. They contained portions of skulls and bones of small quadrupeds unknown to me. I also found the entire skeleton of one of these Owls in excellent condition, and observing a curious bony crest-like expansion on the skull from the base of the cere above to that of the lower mandible, elevated nearly a quarter of an inch from the solid part of the skull, and forming a curve like a horse-shoe, I made an outline of it. On speaking to the officers of the garrison respecting this species of Owl, Lieutenant Constantine Smith, a most amiable and intelligent officer of our army, informed me, that, in the months of July and August of that year, these birds bred more abundantly than at the date above stated. Other persons also assured me that, like the House Pigeon, the Barn Owl breeds at all seasons of the year in that part of the country. The statement was farther corroborated by Mr Lee Williams, a gentleman formerly attached to the topographical Having arrived at Charleston, South Carolina, in October 1833, as soon as my family and myself were settled in the house of my friend the Reverend John Bachman, I received information that a pair of Owls (of the present species) had a nest in the upper story of an abandoned sugar-house in the city, when I immediately proceeded to the place, accompanied by Dr Samuel Wilson and William Kunhardt, Esq. We ascended cautiously to the place, I having pulled off my boots to prevent noise. When we reached it I found a sort of large garret filled with sugar-moulds, and lighted by several windows, one of which had two panes broken. I at once discovered the spot where the Owls were, by the hissing sounds of the young ones, and approached slowly and cautiously towards them, until within a few feet, when the parent bird seeing me, flew quickly toward the window, touched the frame of the broken panes, and glided silently through the aperture. I could not even afterwards observe the course of its flight. The young were three in number, and covered with down of a rich cream colour. They raised themselves on their legs, appeared to swell, and emitted a constant hissing sound, somewhat resembling that of a large snake when angry. They continued thus without altering their position, during the whole of our stay, which lasted about twenty minutes. They were on a scattered parcel of bits of straw, and surrounded by a bank made of their ejected pellets. Very few marks of their excrements were on the floor, and they were beautifully clean. A Cotton Rat, newly caught, and still entire, lay beside them, and must have been brought from a distance of several miles, that animal abounding in the rice-fields, none of which, I believe, are nearer than three or four miles. After making some arrangements with the Negro man who kept the house, we returned home. The eggs from which these young Owls had been hatched must have been laid six weeks before this date, or about the 15th of September. On the 25th of November they had grown much in size, but none of the feathers had yet made their appearance, excepting the primaries, which were now about an inch long, thick, full of blood, and so tender that the least pressure of the fingers might have burst them. As the young grow more and more, the parents feed and attend to them less frequently than when very small, coming to them in the night only with food. This proves the caution of these birds in avoiding danger, and the faculty On the 7th of December I visited the Owls in company with my friend John Bachman. We found them much grown; indeed, their primaries were well out; but their back and breast, and all their lower parts, were still thickly covered with down. On the 6th of January I again saw them, but one of the young was dead, although in good condition. I was surprised that their food still continued to be composed entirely of small quadrupeds, and principally of the rat mentioned above. My last visit to them was on the 18th of January. The two younger ones were now, to all appearance, fully grown, but were yet unable to fly. A few tufts of down still remained attached to the feathers on scattered parts of the body. I took them home. One was killed, and the skin preserved. Now, these facts are the more interesting, that none of the numerous European authors with whom I am acquainted, have said a single word respecting the time of breeding of this species, but appear to be more intent on producing long lists of synonyms than on presenting the useful materials from which the student of nature can draw inferences. I shall therefore leave to them to say whether our species is, or is not, the same as the one found in the churches and ruins of Europe. Should it prove to be the same species, and if the European bird breeds, as I suspect it does, at so different a period of the year, the habits of the American Owl will form a kind of mystery in the operations of nature, as they differ not only from those of the bird in question, but of all other Owls with which I am acquainted. My opinion is, that the Barn Owl of the United States is far more abundant in the Southern Districts than in the other parts. I never found it to the east of Pennsylvania, and only twice in that State, nor did I ever see, or even hear of one in the Western Country; but as soon as I have reached the maritime districts of the Carolinas, Georgia, the Floridas, and all along to Louisiana, the case has always been different. In Cuba they are quite abundant, according to the reports which I have received from that island. I am indeed almost tempted to believe, that the few which have been found in Pennsylvania were bewildered birds, surprised by the coldness of the winter, and perhaps unable to return to the Southern Districts. During my visit to Labrador I neither saw any of Thomas Butler King, Esq., of St Simon's Island, Georgia, sent me two very beautiful specimens of this Owl, which had been caught alive. One died shortly after their arrival at Charleston; the other was in fine order when I received it. The person to whose care they were consigned, kept them for many weeks at Charleston before I reached that city, and told me that in the night their cries never failed to attract others of the same species, which he observed hovering about the place of their confinement. This species is altogether nocturnal or crepuscular, and when disturbed during the day, flies in an irregular bewildered manner, as if at a loss how to look for a place of refuge. After long observation, I am satisfied that our bird feeds entirely on the smaller species of quadrupeds, for I have never found any portions of birds about their nests, nor even the remains of a single feather in the pellets which they regurgitate, and which are always formed of the bones and hair of quadrupeds. Owls which approach to the diurnal species in their habits, or which hunt for food in the morning and evening twilight, are more apt to seize on objects which are themselves more diurnal than otherwise, or than the animals which I have found to form the constant food of our Barn Owl. Thus the Short-eared, the Hawk, the Fork-tailed, the Burrowing, and other Owls, which hunt either during broad day, or mostly towards evening, or at the return of day, will be found to feed more on mixed food than the present species. I have no doubt that the anatomist will detect corresponding differences in the eye, as they have already been found in the ear. The stomach is elongated, almost smooth, and of a deep gamboge-yellow; the intestines small, rather tough, and measuring one foot nine inches in length. Its flight is light, regular, and much protracted. It passes through the air at an elevation of thirty or forty feet, in perfect silence, and pounces on its prey like a Hawk, often waiting for a fair opportunity from the branch of a tree, on which it alights for the purpose. During day, they are never seen, unless accidentally disturbed, when they immediately try to hide themselves. I am not aware of their having any propensity to fish, as the Snowy Owl has, nor have I ever seen one pursuing a bird. Ever careful of themselves, they retreat to the hollows of This species is never found in the depth of the forests, but confines itself to the borders of the woods around large savannas or old abandoned fields overgrown with briars and rank grass, where its food, which consists principally of field-mice, moles, rats, and other small quadrupeds, is found in abundance, and where large beetles and bats fly in the morning and evening twilight. It seldom occurs at a great distance from the sea. I am not aware that it ever emits any cry or note, as other owls are wont to do; but it produces a hollow hissing sound continued for minutes at a time, which has always reminded me of that given out by an opossum when about to die by strangulation. When on the ground, this Owl moves by sidelong leaps, with the body much inclined downwards. If wounded in the wing, it yet frequently escapes through the celerity of its motions. Its hearing is extremely acute, and as it marks your approach, instead of throwing itself into an attitude of defence, as Hawks are wont to do, it instantly swells out its plumage, extends its wings and tail, hisses, and clacks its mandibles with force and rapidity. If seized in the hand, it bites and scratches, inflicting deep wounds with its bill and claws. It is by no means correct to say that this Owl, or indeed any other, always swallows its prey entire: some which I have kept in confinement, have been seen tearing a young hare in pieces with their bills in the manner of hawks; and mice, small rats, or bats, are the largest objects that I have seen them gobble up entire, and not always without difficulty. From having often observed their feet and legs covered with fresh earth, I am inclined to think that they may use them to scratch mice or moles out of their shallow burrows, a circumstance which connects them with the Burrowing Owls of our western plains, which like them have very long legs. In a room their flight is so noiseless that one is surprised to find them removed from one place to another without having heard the least sound. They disgorge their pellets with difficulty, although generally at a single effort, but I did not observe that this action was performed at any regular period. I have mentioned these circumstances, to induce you to examine more particularly the habits of the Barn Owls of The pair which I have represented were given to me by my friend Richard Harlan, M.D., of Philadelphia. They had been brought from the south, and were fine adult birds in excellent plumage. I have placed a ground squirrel under the feet of one of them, as being an animal on which the species is likely to feed. Strix flammea, Linn. Syst. Nat. vol. i. p. 133.—Lath.

Ornith. vol. vi. p. 57. pl. 50. fig. 2.—Nuttall, Manual, part ii. p. 139. Adult Male. Plate CLXXI. Fig. 1. Bill short, compressed, deep, and strong, with a short cere at the base; upper mandible with its dorsal outline straight to the end of the cere, then curved, the sides nearly flat and perpendicular, the edges acute, the tip deflected, with a rounded but sharp-edged point; lower mandible, with the dorsal outline, convex, the sides convex, the edges arched and sharp, the extremity obliquely truncate. Nostrils large, oval, in the fore part of the cere. Head disproportionately large, as are the eyes and external ears. Neck also very short, body rather slender. Legs rather long; tarsus long, feathered, scaly at the lower part; toes large, the hind one short, the inner nearly as long as the middle one; the outer connected by a short web at the base; all covered above with series of small tuberculiform oblong scales, intermixed with a few bristles, and three broad scutella at the end; claws arched, long, rounded above, extremely sharp, that of the middle toe with an edge on the inner sides, which in old birds is transversely cracked. Plumage very soft and downy, blended above, loose beneath. Long bristly feathers at the base of the bill stretching forwards. Eyes surrounded by circles of loose thin feathers; auricular feathers narrow, recurved and compact at the end, forming a ruff. Wings ample, long; second quill longest, third slightly shorter, first next in length; primaries incurvate towards the end, broad and rounded, the first, as usual in the genus, pectinated. Tail rather short, even, of twelve broad rounded feathers. Bill pale greyish-yellow or light horn-colour. Iris bluish-black. Length 17 inches, extent of wings 3 feet 6 inches; bill along the back 1 8/12; tarsus 3 2/12, middle toe and claw 2 7/12. Adult Female. Plate CLXXI. Fig. 2. The female resembles the male, but is considerably larger. Length 18 inches, extent of wings 3 feet 8 inches. This bird is so closely allied to the Barn Owl of Europe, that it is very difficult to characterize the two by any comparative marks. The principal differences are to be found in the size and colouring. The American bird is much larger than the European, as will be seen by the following measurements taken from an adult male. Length 14 inches, extent of wings 3 feet; bill along the back 1 6/12; tarsus 2?, middle toe and claw 2 1/12. The colouring of the American is much darker than that of the European bird, and in the former the ruff is red, whereas it is usually white in the latter; but as both birds present variations of colour, no stress can be laid on this circumstance. The difference that strikes one most on comparing the two, is the greater size of the American bird, and more especially of its tarsus and toes. On the whole, although I suspect they will ultimately be found to be different species, I am unable to point out any satisfactory distinctions. The Ground Squirrel.With the exception of the Flying Squirrel, we have no small quadruped more interesting than this. It occurs in all parts of the United States, and being so beautifully marked in its colouring, is known to every body. It seems to me, by the liveliness of its motions, to be among quadrupeds what the Wren is among birds; for, like it, the Ground Squirrel, full of vivacity, plays as it were with the utmost grace and agility among the rocky debris or the uprooted stumps of trees; and its chatter, although less musical than that of the Little Winter Wren, excites a peculiar pleasure as it comes on the ear. I think I see him as he runs before me with the speed of thought, his tail quite erect, his chops distended with the produce of the woods, until he reaches the entrance of his retreat. Now he stands upright, clatters his little chops, and as I move onwards a single step, he disappears in a moment. Stone after stone I have removed from the fence, but in vain, for beneath the whole the cunning creature has formed its deep and circuitous burrow. With my hatchet I cut the tangled roots, and as I follow the animal into its innermost recesses, I hear its angry voice. I am indeed within a few inches of his last retreat, and now I see his large dark protruded eye; but at this moment out he rushes with such speed that it would be vain to follow him. He has twenty burrows all ready prepared, and, delighted with his foresight and sagacity, I willingly leave him unmolested in that to which he has now betaken himself. The Ground Squirrel varies greatly in its external appearance in different parts of the United States. In the Southern Districts it is smaller than to the eastward, and the farther north you go the lighter are its tints, the differences being at least as great as those between the Barn Owl of America and that of Europe. But the variations are confined to size and intensity of colouring, nor can I perceive any differences indicative of specific distinction. I am not inclined to consider variations of colour sufficient to constitute species, for instance, in the case of the Chimney Swallow of Europe and the Barn Swallow of America; nor is there any reason for believing that very considerable differences in size may not exist in the same species; indeed the fact is very apparent among water birds especially. |
