They grip with two toes on either side of their foot. The first and fourth toes are turned backward.
Their wings are small, usually they measure the same distance as their beak to their tail. with their beak measuring about half of their body length.
The bill is very light and is used as a thermoregulator. The serrations on the beak allow it to chew through almost any fruit or nut. They also eat insects and lizards. They play an important role in dispersing seeds in the jungle.
Unique to the toucan is their ability to snap their tail forward covering their head to sleep.
Toucans usually do not show sexually dimorphism, or difference in the colorations between male and female. This usually means that their colors are not used to attract the opposite sex.

They can flare and control their feathers, and have no down durning any stage of development.
