The legs of the toucan are strong and rather short. Their toes are arranged in pairs with the first and fourth toes turned backward. The majority of toucans do not show any sexual dimorphism in their coloration, the genus Selenidera being the most notable exception to this rule (hence their common name, "dichromatic toucanets"). However, the ...
This is the most vocal of the mountain toucans, and the sexes often duet. The male makes a loud, repeating "tryyyyyyyk" sound and the female makes a drier "t't't't't't't't" noise. The bird utters rattles and clicks loud enough to be heard from over a kilometer away.
The archosaurian shift from larynx to syrinx must have conferred a selective advantage for crown birds, but the causes for this shift remain unknown. [10] To complicate matters, the syrinx falls into an unusual category of functional evolution: arising from ancestors with a larynx-based sound source, the syrinx contains significant functional overlap with the structure it replaced.
The sweet TikTok video was uploaded by the TikTok account for @Chester_the_toucan and people can't get enough of this sweet bird. One person said, "I didn't know banana chickens made noises."
The chestnut-mandibled toucan is a resident breeder in moist lowland forest. The 2–4 white eggs are laid in an unlined cavity high in a decayed section of a living tree, or occasionally in an old woodpecker nest in a dead tree. Both sexes incubate the eggs for at 14–15 days, and the toucan chicks remain in the nest after hatching.
The Choco toucan is one of the "croaker" group of toucans. [3] Its call is "a steadily repeated series of croaking 'kreeork' notes, sometimes speeded up into a 'kriik'." [ 5 ] It also clacks its bill and makes grating sounds with a closed bill.

Keel-billed toucans have zygodactyl feet (or feet with toes 2 and 3 facing forwards, and toes 1 and 4 facing backwards) – two toes face forward and two face back. Because toucans spend a large portion of time in the trees, this helps the birds to stay on the branches of the trees and jump from one branch to another.
