Toucan Beak Adaptations. Charles Darwin thought the toucan's oversized beak was a sexual lure for attracting potential mates, while some modern-day biologists suggested it was either for peeling fruit or to warn off territorial rivals. Favorite places of these handsome people are forests and woodlands of Brazil, Argentina up to the south of North America.
In addition, the beak houses a flat tongue of the same length, which helps the toucan catch insects, frogs, and reptiles.
The Ramphastidae are most closely related to the American barbets.
The birds use them to reach fruit on branches that are too small to support their weight. The beautifully-coloured Keel-billed toucan had almost the entire top part of its beak smashed off with sticks after being targeted by a gang of young men in central Costa Rica. In Brandy and Mr. whisker's there are two TOUCAN twin girls.
