In some species the bill is nearly as large and as long as the body itself. It is light, cellular, and irregularly notched at the edge, having both mandibles arched towards the tip. The tongue is also of a singular form, being narrow and elongated, and literally barbed like a feather. The feet are short--formed, like those of parrots, rather for grasping than for climbing; the tail long, and the wings moderate. It has a straight but laborious flight, and seems awkward, except on the boughs, when it moves lightly and actively from branch to branch. When eating, it throws up its head, apparently to allow the food to fall down its throat with greater ease. When the toucan is at roost, it turns its long tail directly over its back, and thrusts its beak beneath the wing, so as to appear very much like a large mass of feathers. The common or crested toucan (Ramphastos dicolorus) inhabits chiefly the lower part of the Amazon. It is about eighteen inches in length, of a black colour, with a gloss of green. The cheeks, throat, and fore part of the breast are either of a sulphur or orange-yellow. Across the lower part of the breast is a broad crimson bar. The rump is crimson or orange-yellow. The bill is of a dark olive-green, with a pale yellow base, bounded by a thick bar. The tocano pacova has a beak of a rich glowing orange, with a large patch near the tip, a black line round the base, and a number of dark red bars upon the sides. The body and head are black, the throat and cheeks white; while the breast is of a yellow brimstone hue, edged with a line of blood-red. The upper tail-coverts are greyish-white, and the under deep crimson. A large orange circle surrounds the eye, and within it is a second circle of cobalt-blue. A green ring incloses the pupil, with a narrow yellow ring round it. Cuvier's toucan inhabits the woods of the Upper Amazon. There are several smaller toucans, one of which (the Pteroglossus Havirostris) has the most beautiful plumage,--its breast being adorned with broad belts of rich crimson and black. The most curious, however, is the curly-crested toucan (Pteroglossus Beauharnaisii). The feathers on its head consist of thin, horny blades of a lustrous black colour, curled up at the ends, and resembling shavings of steel. The curly crest assumes, indeed, the grotesque form of a coachman's wig dyed black, and produced apparently by the tongs of the hair-dresser. None of the smaller species utter the loud yelping notes of the larger. The cries of the curly-crested toucan are very singular, resembling somewhat the croaking of frogs.
