Earlier scientists believed that the bird might use its bill to defend the nest cavity. These types of birds are closely associated with the American barbets. It points with a downcurved tip and serrated edges. The family includes five genera and over forty different species. Keel-billed toucan at an animal shelter in Samara, Costa Rica. The feathers in the genus containing the largest toucans are generally black, with touches of white, yellow, and scarlet. They are brightly marked and have large, often-colorful bills. A structural complex probably unique to toucans involves the modification of several tail vertebrae. Toucans when threatened come out of the cavity to see off the predator in the open, if at all. They apt to communicate with each other by producing different high-pitched sounds. However, as there is no sexual dimorphism in coloration it is unlikely to be a sexual signal. The long bill helps it to pluck berries from the branches without leaving in a perch. Toucans fly all throughout the tropical South America to as far as northern Argentina. Columbia hosts the most number of toucans with 21 species are found in this country alone. The wings are small, as they are forest-dwelling birds who only need to travel short distances, and are often of about the same span as the bill-tip-to-tail-tip measurements of the bird. The rear three vertebrae are fused and attached to the spine by a ball and socket joint. Black toucanets (Selenidera) and green aracari (Pteroglossus viridis) are the only species in which male-female difference is quite visible. Channel-billed toucan (Ramphastos vitellinus) is the only species being found in Trinidad. Toco toucan ( Ramphastos toco at Iguazu National Park. The Ramphastidae family is most closely related to the American barbets.
The legs of the toucan are strong and rather short. They make their nests in tree hollows and holes excavated by other animals such as woodpeckers —the toucan bill has very limited use as an excavation tool. They are highly unique in their strikingly large and colorful bills. The colorful and large bill, which in some large species measures more than half the length of the body, is the hallmark of toucans. Toucans are often seen in small flocks especially during foraging. The toucanets have mostly green plumage with blue markings. One species is endangered while the other three are Near Threatened. 17 species inhabits Venezuela, Brazil, and Ecuador. Besides, they also use their bill to see other birds off their abandoned habitats—especially those whose nests they raid. Also, the beak allows the bird to reach deep into tree-holes to access food unavailable to other birds, and also to ransack suspended nests built by smaller birds. They seem to possess the most brightly colored plumage along with the prominent unusually long bill. A few species are also seen to fly as far north as Mexico. They generally live in tropical and sub-tropical regions. Males and females are similar in size and color. The tail is rounded and varies in length, from half the length to the whole length of the body. Large raptors try to attack toucans while it is in flight because then it is impossible for the bird to use its bill to defend. Their toes are arranged in pairs with the first and fourth toes turned backward. Keel-billed toucan at the Beardsley Zoo in Bridgeport, Connecticut. They are primarily found in South America south to northern Argentina in the tropical and montane rainforest. However as the research carried on, the belief no longer held true. With their unmistakable appearance of large-sized colorful beaks, toucans can be easily recognized.
