“Keel-billed Toucan’s bills are the colors of the rainbow!”

Keel-billed toucans are also known as “rainbow” toucans due to their large, colorful bills. They are also called “sulfur-breasted toucans” because they have a bright yellow patch on their breasts. These tropical birds thrive in the humid climates of Central and South America. They are not very good fliers and prefer to hop amongst the dense leaves of the canopy. Because they live very high up and do not fly often, they can be hard to spot despite their rainbow bills.

These social birds are monogamous for at least the year they decide to mate, if not subsequent years. In a tree cavity, a female keel-billed toucan will lay anywhere from 2 to 4 eggs. These eggs hatch into chicks after 15-20 days of incubation.
