[Illustration: THE LAUGHING JACKASS (_Paralcyon gigas_, or _Dacelo gigantea_).]
According to Bernstein, this species is one of the commonest of the birds inhabiting Java; and is to be seen on the banks of every river or streamlet that is not at any great distance from trees, and from a projecting stone or branch patiently spying out the approach of any insect or tiny fish. Its flight is usually accompanied by the repeated utterance of its clear loud cry. The nest consists of a bed of dry leaves and moss placed in a hollow in the ground, protected by an overhanging stone. The three or four eggs have a dull white shell.
The BLUE ALCYON (_Cyanalcyon Macleayi_), one of the most beautiful birds of Australia, is blackish blue on the head, as far as the nape; the mantle is bright blue; the wings and tail are black, shaded with blue; the entire under side of the roots of the primary and secondary quills, a broad band round the throat, and an oval spot behind the nostrils, are white; the iris is dark brown, the beak black, and the tarsus blackish grey. The female is less brightly coloured than her mate, and has an irregular, broken line of white around her throat. This species is seven inches long; the wing measures six inches and one-sixth, and the tail two and a half inches.
"This beautiful bird," says Gould, "far surpasses any other Australian Kingfisher in the brilliancy of its plumage. Like the other members of the genus to which it belongs, it is rarely if ever seen near water, and evinces so decided a preference for the open forests of the interior of the country that it has obtained the name of the Bush Kingfisher. It is generally dispersed about in pairs, and feeds on small reptiles, insects, and their larvæ. Its usual note is a loud "pee-pee," uttered with considerable rapidity. It incubates in November and December, sometimes forming its nest in the hollow trunks of trees, and at others excavating for itself a hole in the nest of the tree-ants, which present so singular and prominent a feature in the scenery of the country. The nest of these birds is easily discovered, for on the approach of an intruder they at once commence flying about in a very wild manner, uttering a loud, piercing cry of alarm. The eggs, three or four in number, have a pearly white shell, and are round in form."
