Then, as regards the owl—that bird of the night, who shuns the light of the life-giving sun; for which reason man distrusts and persecutes him. The other birds also regard him with disfavour, and mob him when he ventures forth from his holes by day, big birds and little ones, in common dislike of the uncanny creature. They know full well that this is the nocturnal disturber of woods and fields, and they resent his ways and his manners.
When the twilight is over all and the birds of day have betaken themselves to rest, then most of the owls go forth to hunt for quarry. Noiselessly they flit over the quiet meadows and fields; with those eyes which shun the light they can detect through the dimness of evening the nest where small birds are, and this they rifle. And so in that respect they are harmful. The Short-eared owl will take birds from the size of a lark to that of a plover.
On the other hand, when mice have got the upper hand in house and barn, devouring and spoiling man’s provision, then every species of owl is welcome, even he the superstitious countryman calls the Death-bird. And, again, when the weather favours that pest the field-mouse, and the voles, and they swarm in meadows, cornlands and everywhere, so that the land is full of mouse-runs; from all sides comes that gentle singing from tiny throats and the farmer is at his wits’ end to know how to be rid of the plague. Then in Hungary the mouse buzzards circle by day over the pastures and fields, making war on the gnawing little beasts; and the whole night long the owls take up the same useful work. They fill their crops, each of them, with from twenty to thirty mice, fly to their several trees to digest the meal, and you will find the pellets formed by the birds of the indigestible portions—bones and fur—in and about their nesting-holes. Harmful moths and beetles they also kill.
And so the Owls—barn, the tawny or wood-owl, the long and the short-eared—which in England are the only common species, are undoubtedly the agriculturalists’ good friends, and indeed friends of the whole human race; and many landowners now prohibit the use of the cruel pole-trap in their destruction. Richard Jefferies tells how 200 owls were taken in one pole-trap in a plantation of young fir in his time. Dr. Altum, a great mover in the cause of bird-protection, examined 210 of the wood-owl’s pellets and found in these the remains of 6 rats, 42 mice, 296 voles, 33 shrews, 48 moles, 18 birds and 48 beetles, besides a countless number of cockchafers.
And what can you find to say in favour of the Sparrow? I fancy I hear many a reader ask,—that ubiquitous bird whose impudence is everywhere proverbial. When sparrows in hosts settle down on the corn waiting to be harvested, not only filling their crops but uselessly beating the grain out of the ears, the case is bad, and it is hard then to recall all the good the same birds had done in devouring the seeds of harmful weeds, such as wild mustard, etc.—also to think of the cockchafers in the grub as well as winged—daddy-longlegs, caterpillars, turnip-moth, grubs of cabbage-moth and butterfly, and the moths of both currant and gooseberry. In towns, too, the sparrow is invaluable as a street scavenger. House-flies, those plagues indoors, maggots of fleas, eggs of cockroaches, spiders, centipedes,—all, and many other “small deer” that infest stables, poultry-yards and other precincts of our homesteads the sparrow diligently seeks for.
It is true that the common sparrows multiply too fast and their numbers must be thinned down. This, many a bird-loving landowner and farmer does in various ways. The late Lord Lilford declared the most humane way was to pull down all the nests within man’s reach. There would still be plenty left, in inaccessible places. A humane farmer, the present writer knows in Hampshire, a great wheat-grower, gives the lads round threepence a score for all the sparrows’ eggs they can bring to him. Sparrow-clubs—save the mark!—are schools for cruelty. In one Lancashire parish which I know the vicar encourages the Jackdaw, allowing it to build even in his church steeple, because wherever that bird is, sparrows become more scarce, their young suiting that bird’s palate well. Man has foolishly upset the balance of nature by destroying the natural enemies of the sparrow. Take two neighbouring estates we know in Yorkshire; on the one sparrows, blackbirds, bullfinches and other birds are remorselessly shot during the fruit season; on the other the use of the gun is forbidden. In the garden and orchard of the latter there is always a far greater allowance of fruit than in those of the former.
Only where their natural enemies have become scarce ought man to set his wits to work to compass the destruction of a species.
CHAPTER II.
The Structure of the Bird.
Let us now consider the bird’s bodily structure. Every child knows that the bird’s body is covered with feathers or down, and that what, in the case of mammals are fore-feet, in birds are wings with which they fly.
There are as many kinds of flight as there are kinds of birds. It depends for the most part on the nature of the bird, in a smaller degree on the structure of the wing.
