The Jay Cuckoo is very numerously met with in some parts of Africa, and from thence wanders forth into Europe, appearing occasionally in Greece and Italy. It is often known to breed in Spain. Such of these birds as inhabit Egypt principally frequent the small groups of mimosa that abound in the valley of the Nile, and live in pairs or small parties, according to our own observation, remaining together even during the breeding season. Like its European brother, this species is of a restless and violent temperament, engaging constantly in fierce strife with its male companions during the period of incubation. Its flight is rapid, and so skilful as to enable the bird to penetrate the densest thickets without a moment's hesitation. It rarely descends to the ground, but obtains the insects and caterpillars on which it subsists either while on the wing or when perching among the branches. Its voice, which somewhat resembles that of a Jay, can be heard at a considerable distance, and has a laughing but monotonous sound. The female, like the rest of her congeners, deposits her eggs in another bird's nest. Baedecker describes the egg as of a light blueish green, spotted with grey or brown, and dotted all over with reddish brown; at the broad end the spots take the form of a wreath. In form the eggs are similar to those of other Cuckoos, but in size resemble those of the Jay. * * * * * The KOELS (_Eudynamys_), a small group of Cuckoos inhabiting Southern Asia and Oceania, possess a strong, thick beak, the upper mandible of which is much curved, and hooked at its tip, while the lower portion of the bill is nearly straight. Their feet are strong, their wings of moderate size, the tail long and rounded; the soft plumage is of very uniform hue, that of the male being usually black, and that of the female black spotted with white. THE KOEL, OR KUIL. The KOEL, or KUIL (_Eudynamys orientalis_), is the best known member of the above group. The male is entirely of a glossy greenish black, while the female is of a rich, deep green, spotted with white above, and striped with white on the quills and tail. The under side is white, with black oval markings on the throat, and heart-shaped spots upon the breast. The eye of both is scarlet, the beak pale green, and foot greyish blue. The length of the male is thirteen inches and a half, and the breadth twenty-three inches; while the female measures seventeen inches and a half, and is twenty-four inches across the wings.
