The Magpie: Waterton

It is impossible to have a better or more complete plan of attracting the owls than that which is employed by Mr. Waterton at Walton Hall. He can, and does, attract all kinds of birds to his domain by the simple plan of affording them a secure shelter and the prospect of food. In the case of the owls the first precaution is the only one that is needful, the birds being perfectly capable of finding food for themselves. Possibly a few mice thrown on the ground might assist in attracting the birds; but as they will come when no such precaution is taken, such bait may be omitted.

There is a popular idea that neither the lion, the eagle, or the owl will eat game which they have not killed. Nothing can be more opposed to fact than such a notion : for the lion is generally killed by laying in his haunts a dead animal, which he is sure to eat; the eagle is only too glad to pick up a dead lamb; and the owl will carry off almost any number of dead mice that are placed in its way.

If the reader wishes to attract owls to his premises, he must prepare habitations for them. Knowing that the common barn owl, or white owl, as it is sometimes called, is fond of resting in buildings, Mr. Waterton has taken great pains to erect certain domiciles of which the owls are likely to approve. A large hole made in an old ruin is sure to attract the barn owl, especially if it be well sheltered with ivy, and a stout perch across the cavity may be useful. There are owl-houses in different parts of the domain, all tenanted by some bird, and most of them by the inhabitant for whose use they were made.

The jackdaw is the most pertinacious usurper that can be imagined. Any house that will suit an owl will suit a jackdaw, and the daw is so keen at discovery and so quick at utilizing his faculties, that he takes possession, and fills the hole with sticks, before the owls have a chance of securing their home. If the brown owl is wanted, there are few places like a hollow tree, an article which can often be purchased very cheaply, set up in the grounds, and its interior arranged for the reception of the birds. A writer in the Field newspaper has mentioned that he has been very successful in attracting the brown owl by means of an empty eighteen-gallon cask, made very clean, and fastened in a tree. A perch was placed inside, a convenient entrance-hole cut, and a quantity of very dry touchwood placed within. On this touchwood much of the success seemed to depend, for wherever it was omitted the owls declined to take possession of the cask. In order to fit it for its purpose, it was carefully dried in an oven. The exterior of the cask was painted so as to harmonize with the colours of the tree. Should the reader be unable to fit up such a residence, he may always purchase young owls at a cheap rate, and can train them after his own fashion. In order to show how much amusement may be given by so despised a bird as the owl, the following extract from a private letter is interesting:-- "I saw a curious sight yesterday, which I think quite worth communicating to you. Some folks about us have got a young owl just fledged, and one of the boys had given him for his supper a dead swift, rather high and gamey. While he was enjoying this dainty, a young tabby kitten, aet. about eight weeks, came on the scene, and walking up to the owl, deliberately invited herself to a share in the repast. Mr. Owl did not express any objection, save by expanding his wings over his food, more suo, whereupon pussy crept under the outstretched wing, and went in for her share. It was droll enough to see the two going halves, especially as every now and then the owl got pussy's ear by mistake, and she in like manner began gnawing at his claw. "But the scene reached its climax by the appearance of five young ducklings hatched on Thursday last" (the date of the letter shows that it was written on Friday, and consequently that the ducklings in question were just eight days old), "who surrounded the group, and did what they could to help. The smell of the dead bird attracted, as I suppose, many small flies, which hovered about and settled, now on the owl, now on the cat, and now on the unfortunate swift. They had better have stayed away, however, for the ducklings snapped them up as fast as they alighted, while both the owl and the cat seemed quite to disregard the pokes and pecks which their bodies received from the sturdy bills of the ducklings."

If the reader should keep owls in confinement, where they cannot procure food for themselves, he must remember that they are hungry beings, and give them plenty of food. They will eat almost any kind of meat, but are very fond of mice and small birds, the latter of which they will mostly contrive to swallow entire. There is no doubt that all the British owls feed upon small birds when they can procure them. They have been observed in the act of robbing the nests, in spite of the screams and attacks of the angry parents, and the skulls, feathers, and bones of the murdered birds have been seen in the pellets which all owls disgorge.

In common with most raptorial birds, the owls disgorge the indigestible parts of their food, such as the bones, the feathers, and the skin; and as the owl eats its prey entire, the amount of such substances is remarkable. They are formed into egg-shaped masses, and may be found in plenty in the nest or on the ground near the nest. In some parts of the country these castings are called "quids." When they are first ejected, they are wet and rather tenacious; but they rapidly become dry, and can then be crumbled down into a soft flock-like substance, which forms the bed on which the eggs repose. These eggs can easily be recognised by their peculiar shape and texture. In form they are very globular, their shells are very thin, and the surface is rough and chalk-like, as if some one had ground a piece of chalk into coarse powder, mixed it with gum, and painted the egg with the mixture. Any one who is experienced in such matters knows an owl's egg as soon as he handles it, even though he cannot see the object which he touches. Their method of eating mice is very curious, and that the owl should derive any gratification from the process seems to be rather remarkable. The owl catches the mouse with its foot--a member that is wonderfully fitted for the purpose--and then shifts the mouse to its beak; in this respect differing from the hawks, which hold the prey with the foot, and only use the beak for the purpose of tearing it to pieces. At the Zoological Gardens the falcons may be seen at feeding-time with the meat in their claws, never taking it in the beak when they move, but hobbling about with a lump of raw meat hanging to one foot, and presenting a very absurd spectacle.

When the owl has settled itself into a comfortable position, it gives a kind of snap and a gulp, and in a moment the head of the mouse is in its throat. Another gulp and a shake of the head, and the mouse has disappeared, with the exception of the tail, which hangs on one side of the beak. This part of the process seems to afford the owl the greatest satisfaction, for the bird remains for some time in this attitude, standing perfectly still, but giving the tail an occasional roll in the beak. Suddenly the head goes back with a jerk, the eyes close, there is a mighty gulp, and the tail has followed the mouse into the bird's stomach. The whole process of swallowing the prey is very much like that which may be observed in the toad, the gulping effort to swallow appearing to be equally great in either case. All owls can be treated in a similar manner, so that there is no need of mentioning them individually. If, however, either of the eared owls can be obtained, the young naturalist should not fail to do so. Owls kept in captivity should not be placed in cages, provided that other accommodation can be furnished, but should have a dark recess in which they can sit during the day, and where they can always be found. They are not easily seen by inexperienced eyes, as they have a habit of choosing perches in spots where their colour harmonizes with that of the locality.

When properly treated, the owl can be made quite tame; but unless it be taken when young, it is rather uncertain in temper, biting very sharply. If any one approaches the owl, and hears a quick, snapping sound, as if an elastic piece of wood were "flicked" against a table, he may take it as a warning that the bird does not approve of him, and that he had better not trust his hands too near the owl.

Any one can see how cat-like are the owls in their general physiognomy, as well as in their nocturnal and mouse-loving habits; and they even carry their feline propensities into peculiarities of diet. No animals are less aquatic than the cat, and yet none are more fond of fish. Even the best bred and most carefully-trained cat finds a difficulty in resisting her appetite when she sees fish on the table, and she can hardly have a greater treat than an occasional sprat, herring, or plaice. Angler-cats are not uncommon: several that were accustomed to haunt the water side have been known to catch the fish in shallow water, and would even plunge into deep water for their prey. In like manner the owl is a great fish-lover, and has been seen in the act of dropping into the water, and rising again in the air with a fish in its claws. Now it is an invariable rule with animals of all kinds, that these little aberrations, if we may so term them, are conducive to health: a very familiar instance is the occasional grass-eating propensities of the dog and cat. The young naturalist will therefore consult the health of his owl pets by giving them a fish now and then, as well as a few large insects, in addition to their ordinary diet.
