Toucans are near passerine birds from the neotropics, most closely related to American barbets. They are brightly marked and have large, colorful bills. The family includes five genera and about forty different species. The name of this bird group is derived from Tupi tucana, via French.

Morphology

Toucans range in size from the Lettered Aracari (Pteroglossus inscriptus), at 130 g (4.6 oz) and 29 cm (11.5 inches), to the Toco Toucan (Ramphastos toco), at 680 g (1.5 lb) and 63 cm (29 inches). Their bodies are short (of comparable size to a crow's) and compact. The tail is rounded and varies in length, from half the length to the whole length of the body. The neck is short and thick. The wings are small, as they are forest-dwelling birds who only need to travel short distances, and are often of about the same span as the bill-tip-to-tail-tip measurements of the bird. Binomial name Statius Muller, 1776 The Toco Toucan (Ramphastos toco) is the largest and arguably best known species in the toucan family. ... For other uses, see Crow (disambiguation). ...


The legs of a 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 bills of female toucans are usually shorter, deeper and sometimes straighter, giving more of a "blocky" impression compared to male bills. The feathers in the genus containing the largest toucans are generally black, with touches of white, yellow, and scarlet. The underparts of the araçaris (smaller toucans) are yellow, crossed by one or more black or red bands. The toucanets have mostly green plumage with blue markings. Female (left) and male Common Pheasant, illustrating the dramatic difference in both color and size, between the sexes Sexual dimorphism is the systematic difference in form between individuals of different sex in the same species. ...

The colorful, giant bill, which in some large species measure more than half the length of the body, is the hallmark of toucans. Despite its size it is very light, being composed of bone struts with little solid material between them. The bill has forward-facing serrations resembling teeth, which historically led naturalists to believe that toucans captured fish and were primarily carnivorous, but today we know that they eat mostly fruit. Why the bill is so large and brightly colored is still debated and may be complex. As there is no sexual dimorphism in coloration it is unlikely to be a sexual signal; It does aid in their feeding behavior (as they sit in one spot and reach for all fruit in range, thereby reducing energy expenditure). It has also been theorised that the bill may intimidate smaller birds, so that the toucan may plunder nests undisturbed (see Behaviour). Also, the beak allows the bird to reach deep into treeholes to access food unavailable to other birds, and also to depredate suspended nests built by smaller birds. The beak, bill or rostrum is an external anatomical structure of birds which, in addition to eating, is used for grooming, manipulating objects, killing prey, probing for food, courtship, and feeding their young. ... 1 saw-like shape, consisting in a series of sharp peeks/teeth resembling triangles (the verteces, not the edges) Immagine a series of triangles layed on their edge and connected at that edges vertices, the remaning vertices (the non-connected ones) make-up the serration. ... Within evolutionary biology, signalling theory refers to the scientific theory around how organisms signal their condition to others. ...


A toucan's tongue is long (up to 14-15 cm, or 6 inches), narrow, grey, and singularly frayed on each side, adding to its sensitivity as an organ of taste.


A structural complex probably unique to toucans involves the modification of several tail vertebrae. 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.[1] This is the posture in which they sleep, often appearing simply as a ball of feathers, with the tip of the tail sticking out over the head.

Toucans are primarily frugivorous (fruit-eating), but are opportunistically omnivorous and will take prey such as insects and small lizards. Captive toucans have been reported to actively hunt insects in their cages, and it is possible to keep toucans on an insect-only diet. They also plunder nests of smaller birds, taking eggs and nestlings. This probably provides a crucial addition of protein to their diet. However, in their range, toucans are the dominant frugivores, and as such play an extremely important ecological role as vectors for seed dispersal of fruiting trees. Binomial name Ramphastos dicolorus Linnaeus, 1766 The Red-breasted Toucan (Ramphastos dicolorus) is found throughout central and southern Brazil and south into northern Argentina and is one of the more commonly seen species. ...

Toucans are arboreal and nest in tree holes (either natural cavities or holes excavated by for instance woodpeckers - the toucan bill has very limited use as an excavation tool) laying 2–4 white eggs. The young hatch completely naked, without any down. Toucans are resident breeders and do not migrate. Toucans are usually found in pairs or small flocks, within which bill fencing and wrestling may occur, probably to establish dominance hierarchies. The kinkajou is an arboreal mammal. ... In most birds and reptiles, an egg (Latin ovum) is the zygote, resulting from fertilization of the ovum. ...
