OBJECTIVE FORESTRY

Detailed explanation-1: -1 Toucans are among the world’s noisiest birds. When they sing, they sound like frogs croaking. (Listen to a toucan’s call via the Cornell Lab of Ornithology’s Macaulay Library.) They also make tapping and clattering noises with their bills.

Detailed explanation-2: -Toucans also have several natural predators, including forest eagles, hawks, owls, boas, jaguars, and margays. To protect themselves, toucans use their enormous bill. They also use their loud voices to scare off enemies and alert other toucans to the danger.

Detailed explanation-3: -When toucans sleep, they turn their head so that their long bill rests on their back and their tail is folded over their head. The bird becomes a ball of feathers. Often found in abandoned tree hollows or old woodpecker holes, 5 to 6 adults may sleep in one hole.
