The little three-toed jacamar possesses a few of the brilliant hues which adorn his brethren. The great or broad-billed jacamar is very like a kingfisher. The beak is very broad, while the dilated ridge on the upper mandible is distinctly curved. It feeds very much like the kingfisher,--darting down from a branch to secure, with its bill, the active insects as they fly by. It feeds exclusively on them, however, never attempting to obtain food from the waters. THE JACANA. The light-bodied jacana, supported by its spider-like, widely extended feet, treads over the floating pan-like leaves of the Victoria Regia, and other aquatic plants, without sinking them in any perceptible degree below the surface of the calm pools in which they float. They take up their dwelling on the borders of the remote lakes and igarapes of the Amazonian Valley. They are called by the natives oven-birds, because frequently seen on the pan-shaped leaves of the before-mentioned magnificent lily. The common jacana has a black plumage, with a greenish gloss. The legs are very long and slight,--as are the toes and claws, especially that of the hind-toe, which is nearly straight. The body is about ten inches long; and the beak upwards of an inch, and of an orange colour. The jacana feeds on aquatic insects and vegetable matter. While feeding it utters a low-sounding cluck, cluck, at short intervals. When flying it throws out its long legs horizontally to their full length, generally skimming above the surface, out of danger. Its body is of a peculiarly light construction, so that, large as it appears, it weighs but little when pressing the floating leaves, on which it delights to walk in search of its prey. FRIGATE-BIRD PELICANS. Even to the distance of fifteen hundred miles and more from the mouth of the Amazon, large flocks of the high-flying frigate-birds are descried hovering at an immense height above the stream, preparing to plunge down and seize their finny prey. They measure seven feet from wing to wing, and appear almost to live in the air. The neck is partly bare, and very extensible; the bill long, and hooked at the end; the feet small, and webbed. The body of the male is entirely black, while the hen has the head and neck white. It is probably a different species from the frigate-bird, or sea-hawk, of the Eastern tropical seas. THE HORNED SCREAMER. On the shores of a sand-bank, flocks of wild gulls may be seen flying overhead uttering their well-known cries, sandpipers coursing along the edge of the water, here and there lonely wading birds stalking about, and among them the curious Palamedea cornuta--the anhima of the Brazilians, or the horned screamer of Cuvier--called also the kamichi. Startled by the approach of the canoe, up it flies, its harsh screams resembling the bray of a jackass--but shriller and louder, if possible-- greatly disturbing the calm solitude of the place.
