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<ref>http://www.sciencemag.org/content/325/5939/468</ref>, and often within minutes<ref>http://www.wired.com/2009/07/toucanbill/</ref>.

==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 a hour on the eggs. The chicks are born naked, getting a down covering several days after hatching.
