The black-necked Tufted bill is also the noisiest of the forest birds, producing loud rumbles, trumpets, and screeches. Its nest is built in a hole high in a tree. When eating, always peck the food with the tip of the mouth first, then tilt the neck, throw the food upward, and then open the big mouth to accurately put the food into the throat, without having to go through the long mouth and spend time in the process of "swallowing". The black-necked Tufted Toucan is omnivorous, feeding on fruits, seeds, and insects。

The black-necked Tufted Toucan nests in tree cavities and sometimes preys on the nests of young birds, eating eggs and chicks. - Lay 2 to 4 eggs. Smooth white eggs are piled in unlined holes and hatch in about 16 days.
