Keel-billed toucan

The keel-billed toucan (Ramphastos sulfuratus), also known as sulfur-breasted toucan or rainbow-billed toucan, is a colorful Latin American member of the toucanfamily. It is the national bird of Belize.^[2

including its bill, the keel-billed toucan ranges in length from around 42 to 55 cm (17 to 22 in).^[4] Their large and colorful bill averages around 12–15 cm (4.7–5.9 in), about one-third of its length. It typically weighs about 380–500 g (13–18 oz).^[5] While the bill seems large and cumbersome, it is in fact a spongy, hollow bone covered in keratin, a very light and hard protein.

The plumage of the keel-billed toucan is mainly black with a yellow neck and chest. Molting occurs once per year.^[6] It has blue feet and red feathers at the tip of its tail. The bill is mainly green with a red tip and orange sides.

Keel-billed toucans have zygodactyl feet (or feet with toes facing in different directions) – two toes face forward and two face back. Because toucans spend a large portion of time in the trees, this helps the birds to stay on the branches of the trees and jump from one branch to another.
