Semnornis
The toucan-barbets are small birds in the genus ''Semnornis''. The genus was often included in the paraphyletic Capitonidae, barbets, but recently is usually classified into a distinct family (biology), family, Semnornithidae; alternatively, all barbets might be moved to the toucan family toucan, Ramphastidae as a subfamily, Semnornithinae. Toucan-barbets comprise only two species: the toucan barbet (''S. ramphastinus'') and the prong-billed barbet (''S. frantzii''). Taxonomy The Phylogenetics, phylogenetic relationship between the toucan-barbets and the eight other families in the Order (biology), order Piciformes is shown in the cladogram below. The number of species in each family is taken from the list maintained by Frank Gill (ornithologist), Frank Gill, Pamela C. Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC). Description The ''Semnornis'' barbets are fairly large barbets, measuring between .

Toucan Barbet
The toucan barbet (''Semnornis ramphastinus'') is a Ramphastides, barbet native to western Ecuador and Colombia. Along with the prong-billed barbet, it forms the family Semnornithidae, and is closely related to the toucans. It is a medium-sized barbet with a robust yellow bill. It has striking plumage, having a black head with grey throat and nape, red breast and upper belly, yellow lower belly and grey wings and tail. The toucan barbet is native to humid montane forests, where it occupies all levels of the canopy and is found in both primary and secondary forests, as well as forest edges. It is social, living in small family groups which work together to defend their territories and helpers at the nest, raise the chicks communally. It feeds on fruit and a range of animal prey, with insects being an important part of the diet of chicks. It sometimes joins mixed-species feeding flocks. Chicks are raised in cavities dug into large, usually dead trees. Young toucan barbets are prey ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Prong-billed Barbet
The prong-billed barbet (''Semnornis frantzii'') is a distinctive, relatively large-billed bird native to humid highland forest of Costa Rica and western Panama. Taxonomy and systematics The prong-billed barbet was traditionally placed in family Capitonidae ''sensu lato'' with both Neotropic and Old World barbets. However, morphological, hybridization, and DNA studies have confirmed that this arrangement is paraphyletic; New World barbets are more closely related to toucans than they are to Old World barbets. Therefore New World (Capitonidae ''sensu stricto''), African (Lybiidae), and Asian (Megalaimidae) barbets were each accorded their own families. The prong-billed barbet and the toucan barbet (''Semnornis ramphastinus'') were placed in the new family Semnornithidae. The prong-billed barbet is monotypic. Its specific epithet commemorates the German naturalist Alexander von Frantzius. Description The prong-billed barbet is long and weighs about . Its bill is silvery gra ...

Ramphastidae
Toucans (, ) are Neotropical birds in the family Ramphastidae. They are most closely related to the Toucan barbets. They are brightly marked and have large, often colorful bills. The family includes five genera and over 40 different species. Toucans are arboreal and typically lay two to four white eggs in their nests. They make their nests in tree hollows and holes excavated by other animals such as woodpeckers—the toucan bill has very limited use as an excavation tool. When the eggs hatch, the young emerge completely naked, without any down. Toucans are resident breeders and do not migrate. Toucans are usually found in pairs or small flocks. They sometimes fence with their bills and wrestle, which scientists hypothesize they do to establish dominance hierarchies. In Africa and Asia, hornbills occupy the toucans' ecological niche, an example of convergent evolution. Taxonomy and systematics The name of this bird group is derived from the Tupi word ''tukana'' or the G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Picidae
Woodpeckers are part of the bird family Picidae, which also includes the piculets, wrynecks and sapsuckers. Members of this family are found worldwide, except for Australia, New Guinea, New Zealand, Madagascar and the extreme polar regions. Most species live in forests or woodland habitats, although a few species are known that live in treeless areas, such as rocky hillsides and deserts, and the Gila woodpecker specializes in exploiting cacti. Members of this family are chiefly known for their characteristic behaviour. They mostly forage for insect prey on the trunks and branches of trees, and often communicate by drumming with their beaks, producing a reverberatory sound that can be heard at some distance. Some species vary their diet with fruits, birds' eggs, small animals, tree sap, human scraps, and carrion. They usually nest and roost in holes that they excavate in tree trunks, and their abandoned holes are of importance to other cavity-nesting birds. They sometimes com ...

Pici (taxon)
Pici is one of the two suborders of the order Piciformes. It includes two infraorders, Ramphastides (toucans and barbets) and Picides (honeyguides and woodpeckers). Members of this suborder have been called "true piciforms", as the jacamars of Galbulidae and puffbirds of Bucconidae (of the other piciform suborder Galbuli) were for a time thought to be not closely related to toucans and woodpeckers, but instead to the order Coraciiformes The Coraciiformes are a group of usually colourful birds including the kingfishers, the bee-eaters, the rollers, the motmots, and the todies. They generally have syndactyly, with three forward-pointing toes (and toes 3 & 4 fused at their b .... Sibley, Charles Gald & Ahlquist, Jon Edward (1990): ''Phylogeny and classification of birds''.

Picides
Picides is an infraorder of the order Piciformes that includes woodpeckers and honeyguides. The honeyguides were thought to be closely related to the barbets, as their aerial displays and vocalizations are more similar to each other than either are to woodpeckers. However, phylogenetic analysis has shown that honeyguides and woodpeckers are indeed sister taxa.Moyle, R. G. (2004). Phylogenetics of barbets (Aves: Piciformes) based on nuclear and mitochondrial DNA sequence data. Molecular Phylogenetics and Evolution, 30(1), 187-200. Systematics Despite having only two families, Picides is an extremely widespread group; the family Picidae is the largest and most widespread in the order Piciformes, containing over 200 species in three subfamilies and being found on all continents except Australia and Antarctica. *Infraorder Picides **Family Indicatoridae (honeyguides) **Family Picidae ***Subfamily Jynginae (wrynecks) ***Subfamily Picumninae The piculets are a distinctive subfa ...

Indicatoridae
Honeyguides (family Indicatoridae) are a family of birds in the order Piciformes. They are also known as indicator birds, or honey birds, although the latter term is also used more narrowly to refer to species of the genus '' Prodotiscus''. They have an Old World tropical distribution, with the greatest number of species in Africa and two in Asia. These birds are best known for their interaction with humans. Honeyguides are noted and named for one or two species that will deliberately lead humans directly to bee colonies, so that they can feast on the grubs and beeswax that are left behind. Localized interaction between honeyguides and honey badgers has been reported. Taxonomy The Indicatoridae were noted for their barbet-like structure and brood-parasitic behavior and morphologically considered unique among the non-passerines in having nine primaries. The phylogenetic relationship between the honeyguides and the eight other families that make up the order Piciformes is shown in ...

Megalaimidae
Megalaimidae, the Asian barbets, are a family of birds, comprising two genera with 35 species native to the forests of the Indomalayan realm from Tibet to Indonesia. They were once clubbed with all barbets in the family Capitonidae but the Old World species have been found to be distinctive and are considered, along with the Lybiidae and Ramphastidae, as sister groups. Taxonomy In the past the species were placed in three genera, ''Caloramphus'', ''Megalaima'' and ''Psilopogon'', but studies show that ''Psilopogon'' to be nested within the clade of ''Megalaima''. Since members of this clade are better treated under a single genus, they have been moved to the genus ''Psilopogon'' which was described and erected earlier than ''Megalaima'' and is therefore chosen on the basis of taxonomic priority principles. Nearly all members of the family are now in the genus ''Psilopogon'', with the exception of those in ''Caloramphus'', which are thought to have Genetic divergence, genetically d ...
