THE WORLD BIRDS - An Online Bird Book
Piciformes
The order
Piciformes is made up of the woodpecker family Picidae plus 8 other families. Picidae make up about half of the species. In general, the Piciformes are insectivorous, but some exceptions eat mostly fruit. Nearly all Piciformes have parrot-like feet—two toes forward and two back, an arrangement that has obvious advantages for birds that spend much of their time on tree trunks. And most Piciformes do not have down feathers at any age, only true feathers. All nest in cavites.
Toucans,
Toucantes, and
Aracaris are birds of Ramphastidae family. They reside in the neotropics (i.e. Southern Mexico, Central, South American, and Caribbean region). The family is most closely related to the American barbets. They are brightly marked and have large, colorful bills which is the hallmark of toucans. Despite its size, the bill it is very light, being composed of bone struts filled with spongy tissue between them. The large bill of the toucan is a highly efficient thermoregulation system. Also, it allows the bird to access food (they eat mostly fruit) unavailable to other birds or save energy by not having to jump to another branch. The bills of female toucans are usually smaller, but similar in colorization. Because their bill is so large, it can be a challenge to transfer the food they are holding in the bill to their mouth. They have developed an rather unique way to get the food into swallowing position - they toss the item into the air and catch it with their open mouth. Or as happens relatively often, they miss the catch and have to get other piece of food!

Not only are the toucans famous for their bills, those bills are one of the best ways to differentiate between toucan species. Almost every species' bill has unique colorization and or markings. For those species where the bill differences are too subtle for differentiation, throat and bib coloration are also helpful as can be bare skin around the eyes.
Toucans range in size 29-63 cm, the smaller ones are call toucanets. The wings are small, as they are forest-dwelling birds that only need to travel short distances. The majority of toucans do not show any sexual dimorphism in their coloration. They make their nests in tree hollows and holes excavated by other animals, but usually enlarged by both toucan parents. Some have also been recorded nesting in holes in earth-banks and terrestrial termite-nests.
They roost in tree cavities at night, often many in a relatively small space. The rear three vertebrae are fused and attached to the spine by a ball and socket joint. Because of this, toucans may snap their tail forwards until it touches the head. This is the posture in which they sleep which allows for dense sharing of roosting cavities.
Toucans, as is true for most members of the
Piciformes order, have zygodactyl feet with toes facing in different directions – 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. Since toucans only infrequently walk on this ground, this jumping behavior while in trees explains why they have strong legs.
In flight they alternates between a burst of rapid flaps with the relatively short, rounded wings, and gliding.
Many of the toucan species are threatened due to a combination deforestation, poaching for pets, and also hunting for food. Hopefully some of these assessments are pessimistic because of insuffient data and some species may exhibit a higher tolerance for habitat modification than is used in mathematical projections of population decline.
Genus Andigena
The mountain-toucans are found in humid highlands in or near the Andes. They are colorful birds with eye-catching plumage. The backs are brownish-olive and they have black caps. They nest in tree cavities located high above the ground.

Genus Aulacorhynchus
These relatively small green toucans range from 30 to 45 cm long. They are usually found in moist montane woodlands. Their favorite food is fruit, but insects are also eaten. Most are found in South America along the Andes, but the northern emerald toucanet is found in Mexico and Central America. Their nest cavities are located in a tree, usually high off the ground.

Genus Pteroglossus
The aracaris are brightly colored and have large bills that can often an identifying feature. Most aracaris, unlike other toucans, have one or more colored belts on their underparts. That is usually their best identifiable feature. They are 29 to 48 cm long.

Genus Ramphastos
These toucans all have black wings, tails, and thighs. They mainly eat fruit but will eat insects and small prey. These toucans, ranging from 52 to 69 cm, are larger than the
toucanets.

Genus Selenidera
These toucanets are found mainly in rainforests of South America with the yellow-eared toucanet also found in Central America. All of the species have green upperparts and red under-tail coverts. All males have a black cap, nape, throat, and breast. They also have an orange or yellow stripe behind the eye. Females resemble the males, but may have black replaced by reddish-brown or grey in the case of the Guianan toucanet. The toucanets range from 31 cm to about 41.
