Toucans (in Portuguese: Tucano, Spanish: Tucán) are tropical birds from South America. They are brightly marked and have enormous colorful bills. 

Toucans are fruit eating, but will take insects and other small prey. They are arboreal and nest in tree holes laying 2–4 white eggs. Toucans do not migrate. 

The Keel-Billed Toucan, Ramphastos sulfuratus, is a South American bird with a large beak. This social bird lives in small flocks in lowland rainforests, but as it is a poor flyer, the toucan moves mostly by hopping around trees. Toucans roost in holes in trees, and they have a croaking call that sounds like "RRRRK". 

Toucans eat mostly fruit, but also eat bird eggs, insects, and tree frogs. Toucans swallow fruit whole and then regurgitate the seeds; this disperses viable living seeds in the forest. 

The Channel-billed Toucan (Ramphastos vitellinus) is a near-passerine bird that breeds in Trinidad and in tropical South America east of the Andes and as far south as southern Brazil. The western form of this bird, the Yellow-ridged Toucan, was previously considered to be a separate species, Ramphastos culminatus, but the two races readily interbreed. 

This species is a resident breeder in moist lowland forest. The white eggs are laid in a high, unlined tree cavity. 

Like other toucans, the Channel-billed is brightly marked and has a huge bill. It is typically 48cm long with a 9-14cm bill. Sexes are similar. Both sexes are alike in appearance, and they are both active in raising the young. There is have a gestation period of 18 days, and the parents both incubate for 15 to 16 days. However, they can be impatient sitters, often leaving their eggs uncovered for hours at a time. Newborn toucans remain in the nest after hatching. They are blind and naked at birth, and their eyes open after about 3 weeks. They have short bills and specialized pads on their heels to protect them from the rough floor of the nest. The feathers do not begin to expand until they are nearly 4 weeks old. They're helpless and unable to leave the nest for about 8 weeks, dependent upon both parents to feed them. After this, the young can care for themselves. They begin to leave the nest after 40 to 50 days, depending on size. 

The eastern nominate race has a black bill, upperparts and tail, and a red rump. The bare eye patch and bill base are blue, the throat is white and the breast shows successive bands of yellow, whitish and red before reaching the black belly. The under tail is black apart from red under tail coverts. 

The subspecies culminatus has a yellow top ridge to its black bill, and the throat and breast are white, with just a red band separating the latter from the black belly. 

The Channel-billed Toucan is an arboreal fruit-eater, but will take insects and other small prey.  

The Toco toucan is the most well-known and largest member of the toucan family and is commonly found in zoos. They live in South American rainforests. 

Toco toucans have striking plumage with a black body, white throat and a blue eye ring. The most noticeable feature however is its huge yellow beak, which looks heavy but is incredibly light due to air pockets. They are 25 inches long and their beak measures 8 inches. 

The toco toucans eat mainly fruit using their beak but will also occasionally eat insects and bird eggs. They nest and roost in holes in trees.
