Eliminate Enemies.—One great enemy of the birds, however, must be guarded against—the domestic cat. This can be done fairly effectively by means of a cat-proof fence.
Gunners and cats having been eliminated, few other enemies of birds need be seriously considered. Bird-catching Hawks are not often numerous in the neighbourhood of cemeteries. Red squirrels are accused of pilfering from birds' nests, and when abundant they may constitute a menace.
Properly constructed bird boxes, wisely placed, have often proved a means of increasing bird life to an astonishing degree; and they are absolutely the only inducement to hole-nesting varieties to remain during the summer in a cemetery from which all standing dead wood has been removed. Even the strong-billed Woodpecker will not abide in a region where the only trees are living ones, unless, perchance, an artificial nest entices the resplendent and dashing Flicker to tarry. Many a Bluebird, with its azure coat gleaming in the sunlight, visits the cemetery in early spring. From perch to perch he flies, and in his plaintive note can be detected the question that every bird asks of his mate: "Where shall we find a place for our nest?" In the end he flies away. Therefore when the roses and lilies bloom the visitor is deprived of the Bluebird's cheery song, for the little fellow and his mate have departed to the neighbouring farm where they may be found, perhaps, in the old apple orchard.
A few cents expended for lumber and a very little labour in the making of a small box to be attached to the side of a tree or erected on a post, are all that is needed to keep the Bluebirds where they can cheer the hearts of sorrowing visitors. The tiny Wrens, whose loud bursts of song are entirely out of proportion to their size, can be attracted in summer to the proportion of two pairs or more to every acre.
It is a curious fact, of which I believe but little has been written, that birds that build open nests may often be induced to remain in a locality if attractive nesting material is placed within easy reach.
In many a cemetery Orioles could be tempted to weave cradles among the swaying elm limbs if strings and fragments of brightly coloured yarns were placed where the birds could find them. Baron von Berlepsch, whose experiments in attracting birds to his place in Germany have been widely advertised, found that when the tops of bushes were drawn in closely by means of a wire or cord, the resulting thick mass of leaves and twigs offered so fine a place for concealing nests that few birds could resist the temptation to use them.
Other means of rendering a cemetery alluring to nesting birds will readily present themselves when an active interest is developed in the subject. A little thought, a little care, and a little trouble, would make it possible for many birds to dwell in a cemetery, and it must be remembered that unless they can nest there, the chances are that no great volume of bird music will fill the air.
