Population statistics

Toucan refers to any one of 38 species of Central and South American birds characterized by bulky bodies and long, often colorful bills.

Description

Toucans range in size from 12 to 29 inches in length. Their bodies are compact, and have plumage which in most species bear bold patterns of red, green, yellow, blue, orange, black, or white. Smaller species tend to have less-gaudy or dull plumage. All species have short, rounded wings, a long, graduated tail, and short, strong legs with zygodactyl feet, i.e. two toes pointing forwards, two toes pointing back.

The bill is the most distinctive characteristic of the birds. It is large; in some species the bill is half the body length, yet remarkably light due to a spongy structure within. Boldly-colored, the bills may serve as displays in mating or as intimidation against other birds near their nesting areas, in addition to being an efficient thermal radiator to cool the birds down,[1] and often within minutes.[2]

Nesting

Nesting occurs in tree holes, either those formed via natural decay or in holes created by other birds. Two to four eggs are laid, with both parents incubating; they are restless during this period, seldom spending more than an hour on the eggs. The chicks are born naked, getting a down covering several days after hatching.
