The Surukua inhabits the primitive forests of Southern Brazil and Northern Paraguay, and passes its life in a state of the utmost inanition, remaining motionless for hours together, upon a branch, and scarcely rousing sufficiently to turn its head at the sight of a passing insect; so complete is this condition of dreamy indolence, that Azara assures us one of these birds may be struck down from its perch with a stick. The flight of this species is soft and owl-like. The eggs are deposited in holes excavated in such nests of the termite as are situated upon trees. Azara mentions having seen a Surukua hanging like a Woodpecker from the moss, as it hollowed out a cavity with its beak, his mate meanwhile remaining quietly perched upon a neighbouring branch, and apparently stimulating her mate to renewed exertions by her gestures and glances; at this period, the constantly-repeated cry of the male resembles the syllables "pio, pio." The eggs, two to four in number, and of a white colour, are laid in September. The flesh of the Surukua is excellent. THE POMPEO. The POMPEO (_Trogon viridis_) is of a splendid steel-blue, shimmering with green on the crown of the head, nape, sides of the throat, and upper breast; the back, shoulders, and upper wing-covers are of a metallic green, shading into blue on the rump; the belly and vent are bright, deep yellow. The exterior feathers of the wing-covers and the quills are black, the latter edged with white; the centre tail-feathers are green, bordered with black towards the extremity. The next in order are black with a green edge; the three outermost are white at the tip and on the exterior web. In the female the back is deep grey, the belly pale yellow, and the feathers of the wing-covers delicately striped with white. The eyes of both sexes are brown, the beak pale greenish white, and foot blackish grey. This species is twelve inches and three-quarters long, and eighteen inches and a half broad; the wing measures five inches and three-quarters, and the tail five inches and one-third.
