Keel-billed toucans are mostly black with yellow neck and chest. Their long, square tail is red at the base on the underside, and white at the base on top. They have blue feet, and the large bill is light green with a red tip and orange blazes down each side. The keel-billed toucan’s bill averages 5-6 inches, but can be up to 1/3 of the bird’s total length. Females are slightly smaller than males. Also called the Rainbow Toucan.
