Toucan toby jug produced in Japan circa 1950. Toucans are members of the Neotropical near passerine bird family Ramphastidae and are most closely related to the American barbets. They are brightly marked and have large, often colorful bills. Toucans are arboreal and typically lay 2-4 white eggs in their nests. They make their nests in tree hollows and holes excavated by other animals such as woodpeckers, the toucan bill has very limited use as an excavation tool. When the eggs hatch, the young emerge completely naked, without any down. Toucans are usually found in pairs or small flocks, are resident breeders and do not migrate. They sometimes fence with their bills and wrestle, which scientists hypothesize they do to establish dominance hierarchies.
