Keel-billed toucan
The female keel-billed toucan will lay  1-4  white eggs in a natural or already-made tree cavity. The male and female share in the caring of the eggs, both taking turns incubating. The eggs hatch about 15–20 days after being laid.  After hatching, the male and female take turns feeding the chicks.  When the chicks hatch, they have no feathers, and have their eyes closed for about 3 weeks. The chicks stay in their nest for eight to nine weeks while their bills develop fully.
