Black-billed Toucans nest in tree holes, the preferred hole is good wood, the opening width is just enough for adult birds to drill into, the hole depth of 17 cm ~ 2 meters. The presence of suitable burrows near the root of the tree will also attract birds that normally nest in high places to nest near the ground. - Lay 2 to 4 eggs. Smooth white eggs are piled in unlined holes and hatch in about 16 days. The hatchlings are completely naked and need at least three weeks to open their eyes, and after hatching, it takes more than 50 days for the chicks to live their lives independently in the leaf cluster.

The outside is a thin sheath of keratin, the inside is hollow, but there are many thin bone support rods staggered. The tongue of the black-billed toucan is very long, the margin of the beak is clearly serrated, and there is no mouth beard around the base of the beak. The skin on the exposed part of the face and jaw is usually brightly colored. The eyes are light in color, with dark shadows in front and behind the pupil, making their eyes appear to form a horizontal slit.
