The Keel-billed Toucan (Ramphastos sulfuratus)
A perched Keel-billed Toucan
The Keel-billed Toucan (Ramphastos sulfuratus), also known as the Sulfur-breasted Toucan and the Rainbow-billed Toucan, is a colourful Latin American member of the Toucan family. It is in fact the national bird of Belize.
Including its bill, Keel-billed Toucans range in length from around 17 to 22 inches (42–55 cm). Their large and colourful bill averages around 5-6 inches (12–15 cm), about one-third of its length. 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. 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. In the case of the Keel-billed Toucan, it has two toes facing forward and two facing back. Because the Toucans spend a large portion of time in the trees, this helps for the birds to stay on the branches of the trees and hop from one to another.
The Keel-billed Toucan can be found from Southern Mexico to Venezuela and Colombia. It roosts in the canopies of tropical, subtropical, and lowland rainforests, up to altitudes of 1,900 metres. It roosts in holes in trees, often with several other toucans. This can be very cramped, so the birds tuck their tails and beaks under their bodies to conserve space while sleeping. Adding to the lack of space, the bottoms of the holes are often covered with pits from the fruit the toucans have eaten.
Like many toucans, Keel-billed is a very social bird, rarely seen alone. It travels in small flocks of approximately six to thirty individuals through lowland rainforests; it is a poor flyer, and moves mostly by hopping through trees. It has a family structure within the group. Birds will often “duel” with each other using their bills, and throw fruit into each other’s mouths.
Keel-billed Toucans live together in these groups, often sharing cramped living quarters of holes in trees. Able to utilize human-altered habitat to some extent, this widespread bird is considered to be a Species of Least Concern by the IUCN.
The diet of Keel-billed Toucans consists mostly of a wide range of fruits, but may also include small birds, eggs, insects and reptiles. The bill, surprisingly dexterous, allows this toucan to utilize a large variety of fruits that might not otherwise be reached. When eating the fruit, it uses its bill to dissect the fruit, and then tosses its head back to swallow the fruit whole.
The female Keel-billed Toucan will lay a clutch of two to four (rarely one) white eggs in a natural or already-made tree cavity. The male and female both share in the caring of the eggs, both taking turns incubating. The eggs hatch approximately 15–20 days after being laid. After hatching, the male and female again take turns feeding the chicks. When the chicks hatch, they have no feathers, and have their eyes closed for approximately three weeks. The chicks have adequately formed heel pads, which assist on the pit-covered bottom of the nest. The chicks stay in their nest for approximately eight to nine weeks while their bills develop fully and they are ready to fledge from the nest.
