We learn from Le Vaillant, Blyth, and others, that the Drongos are in many respects highly endowed, their instincts acute, their various senses well developed, and their movements through the air distinguished by great lightness and activity. So acute is their vision that, like the Swallow, they dart upon a flying insect from a considerable distance with a rapidity that renders escape almost impossible, and, as we have said, readily destroy their game even in the twilight. Except when engaged in seeking food, they rarely come to the ground; indeed, they seem to have considerable difficulty in using their delicate feet, even whilst in the trees, merely employing them as a means of clinging to the branches, and appearing quite incapable of hopping from one twig to another with anything like a sprightly motion. Such acts as bathing or drinking are carried on, as in the case of the Swallow, whilst the birds are upon the wing. All the members of this group are lively, noisy, and active. They exhibit the utmost courage in defending their mates and nestlings from danger, several individuals often combining together to drive away a common foe. They constantly attack Owls with great spirit, and Gurney tells us that they frequently endeavour to battle with the larger birds of prey. So violent are they during the season for choosing a mate, that Jerdon mentions having seen four or five of these desperate rivals rolling together upon the ground, as they fought in a paroxysm of rage and jealousy. All the various tribes of Drongos appear to subsist exclusively upon insects, more particularly upon bees and wasps; some large species also devour grasshoppers, dragon-flies, and butterflies, but, like their smaller brethren, prefer such insects as are furnished with stings, thus often rendering themselves extremely troublesome to the owners of bees. At the Cape of Good Hope they are known under the name of "Bee-eaters." Le Vaillant tells us that they seem to know exactly at what hour the heavily-laden insects return to their hives, and adroitly relieve them of their burdens, strewing the ground with the wings and bodies of the victims. We learn from Gurney that they are often attracted by the smoke from the conflagrations that occasionally burst forth upon the arid plains of their native lands, for they know well that the devouring flames will drive forth a host of insects, and thus afford a rich and abundant supply of food. Philipps mentions an amusing instance of the cunning displayed by some of these birds whilst engaged in the pursuit of a meal. Upon one occasion, he tells us, he saw a locust closely pursued by a bird that was almost near enough to seize it, when an observant Drongo, having espied the tempting morsel, and finding it impossible to reach the spot in time, suddenly uttered the cry of terror usually employed to signal the approach of a Hawk; the ruse succeeded; the other bird instantly darted away to seek safe shelter, leaving the
