THE SHORT-EARED OWL
ASIO ACCIPITRÍNUS
Face whitish; beak black; iris yellow; egrets inconspicuous, of a few black feathers; eyes encircled by brownish black; upper plumage dusky brown, edged with yellow; lower pale orange, streaked with brown. Length sixteen inches; breadth thirty-eight. Eggs white.
From the name, Hawk-Owl, sometimes given to this species, we should expect to find this bird not so decidedly nocturnal in its habits as the preceding; and such is the case; for, though it does not habitually hunt by day, it has been known to catch up chickens from the farmyard, and has been seen in chase of pigeons. If attacked during daylight, it does not evince the powerless dismay of the last species, but effects a masterly retreat by soaring in a spiral direction until it has attained an elevation to which its adversary does not care to follow it. Unlike its allies, it frequents neither mountains nor forests, but is found breeding in a few marshy or moorland districts; later in the year it is met with in turnip fields and stubbles. As many as twenty-eight were once seen in a single turnip-field in England; from whence it has been inferred that in autumn the Short-eared Owls are gregarious, and establish themselves for a time in any place they fall in with, where field-mice or other small quadrupeds are abundant. In England this bird is not uncommonly started by sportsmen when in pursuit of game. It then flies with a quick zigzag motion for about a hundred yards, and alights on the ground, never on a tree. By some it is called the Woodcock-Owl, from its arriving and departing at about the same time with that bird; it is not, however, invariably a bird of passage, since many instances are on record of its breeding in this country, making a rude nest in a thick bush, either on the ground, or close to it, and feeding its young on mice, small birds, and even the larger game, as Moor-fowl, a bird more than double its own weight. The Short-eared Owl affords a beautiful illustration of a fact not generally known, that the nocturnal birds of prey have the right and left ear differently formed, one ear being so made as to hear sounds from above, and the other from below. The opening into the channel for conveying sound is in the right ear, placed beneath the transverse fold, and directed upwards, while in the left ear the same opening is placed above the channel for conveying sound, and is directed downwards.
In the severe weather of January, 1861, I had the gratification of seeing three or four of these Owls among the sand-hills of the coast of Norfolk, near Holkham. I imagined them to be in pursuit of the Redwings and other small birds which had been driven by the intense cold to the sea-coast, since they flew about as Hawks do when hunting for prey, and occasionally alighted among the sand-hills. I even fell in with several heaps of feathers, showing where some unhappy bird had been picked and eaten. A few days afterwards, however, I inquired at another part of the coast whether there were any Owls there, and received for an answer, 'No, because there are no Rabbits'; from which I inferred that these birds have the reputation of hunting larger game than Thrushes, a charge which the size and power of their hooked talons seem to justify.
THE TAWNY OWL
SYRNIUM ALÚCO
Beak greyish yellow; irides bluish dusky; upper parts reddish brown, variously marked and spotted with dark brown, black, and grey; large white spots on the scapulars and wing coverts; primaries and tail feathers barred alternately with dark and reddish brown; lower parts reddish white, with transverse brown bars and longitudinal dusky streaks; legs feathered to the claws. Length sixteen inches; breadth three feet. Eggs dull white.
This bird, the Ulula of the ancients, took its name from the Latin ululare; the word used to denote, and partially to imitate, the cry of the wolf; it enjoys also the doubtful honour of giving name to the whole tribe of 'Owls', whether they howl, hoot, or screech. This species is much more common than the Barn Owl in many districts, although it is decreasing in others. Owing to its nocturnal habits, and dusky colour, it is not so often seen as heard. It has many a time been my amusement to repair, towards the close of a summer evening, to a wood which I knew to be the resort of these birds, and to challenge them to an exchange of greetings, and I rarely failed to succeed. Their note may be imitated so exactly as to deceive even the birds themselves, by forming a hollow with the fingers and palms of the two hands, leaving an opening only between the second joints of the two thumbs, and then by blowing with considerable force down upon the opening thus made, so as to produce the sound hoo-hoo-hoo-o-o-o. I have thus induced a bird to follow me for some distance, echoing my defiance or greeting, or whatever he may have deemed it; but I do not recollect that I ever caught sight of the bird.
Squirrels, rats, mice, moles, shrews, and any small birds that he can surprise asleep, with insects, form his principal food. These he hunts by night, and retires for concealment by day to some thick tree or shrubbery, either in the hill country or the plains. The nest, composed principally of the dried pellets of undigested bones and fur, which all the Owls are in the habit of disgorging, is usually placed in a hollow tree: here the female lays about four eggs, from which emerge, in due time, as many grotesque bodies enveloped in a soft plush of grey yarn: destined, in due time, to become Tawny Owls. The full-grown females are larger than the males, and, being of a redder tinge, were formerly considered a distinct species. The old birds utter their loud hoo-hou! or to-whit, in-who! chiefly in the evening.
