The Umbrella Birds are inhabitants of Peru, where they particularly frequent the precipices on the eastern side of the Cordilleras, to an altitude of 3,000 feet above the sea; and from thence are met with as far as Rio Negro, and the boundaries of Chile. They associate in small flocks, which subsist principally upon fruit of various kinds, and live almost entirely at the summits of lofty trees. Their remarkable cry, which resembles the lowing of a cow, is most frequently heard just before sunrise and after sunset. We are entirely without particulars as to their nidification and manner of breeding. * * * * * The BELL BIRDS (_Chasmarhynchus_)--so called from the resemblance of their voices to a muffled bell--constitute a group with whose habits we are much more familiar. Their body is compact, and about as large as that of a Pigeon. The wings, in which the third and fourth quills exceed the rest in length, are long, and extend as far as the centre of the tail: the latter is slightly rounded at its tip. The beak is about half as long as the head, and so much depressed as to be far broader than it is high; the upper mandible is slightly arched, and curves somewhat at its tip, behind which is a small tooth-like appendage. The gape is remarkably large. The tarsi are short, and the toes long. The thick plumage is composed of small feathers, and takes the form of bristles in the region of the beak, which is also furnished with very remarkable fleshy appendages resembling those possessed by the Turkey. The coloration of the feathers varies very considerably, not only in the four species that compose the group, but in the different sexes. THE BARE-NECKED BELL BIRD. The BARE-NECKED BELL BIRD (_Chasmarhynchus nudicollis_). This bird, which is called "The Blacksmith" by the Brazilians, is entirely of a pure snow-white, with the exception of the bridles and throat, which are bare and of the colour of verdigris. The eyes are greyish brown, the beak black, and the feet flesh-pink. The length of this species is about ten, and its breadth nineteen inches; the wing measures nine inches and three-quarters, and the tail three inches and a quarter. The female is not quite so large as her mate, she is black upon the throat and top of the head; the upper part of her body is of a siskin-green, the under side yellow, longitudinally spotted with black, and streaked with whitish and yellowish lines upon the throat. The young male resembles the mother until it is one year old, when it acquires white spots, and only in its third year appears in the garb of the adult. THE ARAPONGA.
