Significant features
Distribution and Habitat
The Red-necked Tufted Toucan is found in South America (including Colombia, Venezuela, Guyana, Suriname, Ecuador, Peru, Bolivia, Paraguay, Brazil, Chile, Argentina, Uruguay, and the Falkland Islands).
The Red-necked Toucan inhabits warm forests and edge areas, and prefers to perch on treetops.
Appearance
The Red-necked Toucan somewhat resembles a hornbill in appearance. Its upper body is brownish-black, with a deep red rump and a typically chestnut head. The underparts are predominantly yellow with numerous black or red markings forming a large breast patch. The long beak displays a two-tone combination of black and yellow. The beak edges are generally distinctly serrated, and the exterior is black or ivory, somewhat resembling teeth. Despite its large beak, the Red-necked Toucan weighs less than 30 grams. Its beak bone structure is unique; it is not a dense solid but rather a thin shell with a porous, spongy tissue filled with extremely fine fibers running through it, allowing it to feel no pressure.
The tufted-tongue toucan is one of the few toucan species with obvious sexual dimorphism; the sex of chicks can be determined by their plumage when they are four weeks old.
Detailed introduction
The Red-necked Aracari, scientifically known as Pteroglossus bitorquatus, has three subspecies.
The Red-necked Tufted Toucan is one of the noisiest forest birds, capable of producing booming, horn-like, and piercing calls. Its nests are built high in tree cavities. When eating, it first pecks at its food with the tip of its beak, then tilts its neck back, tosses the food upwards, and then opens its large beak to accurately swallow it, avoiding the time spent swallowing through its long beak. The Red-necked Tufted Toucan is omnivorous, feeding on fruits, seeds, and insects.
The Red-necked Tufted Toucan nests in tree cavities, sometimes raiding nests of smaller birds and eating the eggs and chicks. It lays 2-4 eggs at a time. The smooth, white eggs are laid in an unlined burrow and incubate for about 16 days. The chicks hatch naked and take at least 3 weeks to open their eyes. They begin their lives about 45 days after hatching.
