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''.

Magellanic Woodpecker
The Magellanic woodpecker (''Campephilus magellanicus'') is a species of large woodpecker found in southern Chile and southwestern Argentina; it is resident within its range. This species is the southernmost example of the genus ''Campephilus'', which includes the famous ivory-billed woodpecker (''C. principalis'').

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 ...

Zygodactyl
In biology, dactyly is the arrangement of digits (fingers and toes) on the hands, feet, or sometimes wings of a tetrapod animal. The term is derived from the Greek word () meaning "finger." Sometimes the suffix "-dactylia" is used. The derived adjectives end with "-dactyl" or "-dactylous." As a normal feature Pentadactyly Pentadactyly (from Greek "five") is the condition of having five digits on each limb. It is traditionally believed that all living tetrapods are descended from an ancestor with a pentadactyl limb, although many species have now lost or transformed some or all of their digits by the process of evolution. However, this viewpoint was challenged by Stephen Jay Gould in his 1991 essay "Eight (or Fewer) Little Piggies," where he pointed out polydactyly in early tetrapods and described the specializations of digit reduction. Despite the individual variations listed below, the relationship is to the original five-digit model. In reptiles, the limbs are pentadacty ...

Charles Sibley
Charles Gald Sibley (August 7, 1917 – April 12, 1998) was an American ornithologist and molecular biologist. He had an immense influence on the scientific classification of birds, and the work that Sibley initiated has substantially altered our understanding of the evolutionary history of modern birds. Sibley's taxonomy has been a major influence on the sequences adopted by ornithological organizations, especially the American Ornithologists' Union. Life and work Educated in California (A.B. 1940; Ph.D. 1948 in Zoology, University of California, Berkeley. Minor fields: Paleontology, Botany), he did his first fieldwork in Mexico in 1939 and 1941, then in Solomon Islands, Bismarck Archipelago, New Guinea, and the Philippines during World War II while on leave from the U.S. Navy, in which he was Ensign to Lieutenant in the Communications and Medical Service Corps. He was based for much of the war at Emirau Island, in what is now New Ireland Province of Papua New Guinea. His first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 base), though in many kingfishers one of these is missing. The members of this order are linked by their "slamming" behaviour, thrashing their prey onto surfaces to disarm or incapacitate them. In the past, Coraciiformes encompassed all anisodactyl (including syndactyl) members of the Cavitaves. This means that the birds currently classified in Leptosomiformes ( cuckoo-roller) and Bucerotiformes ( hornbills, hoopoes and allies) were formerly classified in Coraciiformes. This is largely an Old World order, with the representation in the New World limited to the dozen or so species of todies and motmots, and a mere handful of the more than a hundred species of kingfishers. The name Coraciiformes means " raven-like". Specifically, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galbuli
Galbuli is one of the two suborders of the order Piciformes. It includes two families, Bucconidae (puffbirds) and Galbulidae (jacamars), both restricted to the Neotropical realm, Neotropics (in contrast to the more widespread suborder Pici (taxon), Pici). Systematics It was thought the jacamars and puffbirds were not closely related to toucans and woodpeckers, but instead related to the order Coraciiformes. However, analysis of nuclear DNA in a 2003 study placed them as sister group to Pici, also showing that the groups had developed Dactyly#Zygodactyly, zygodactyl feet (two toes facing forward and two aft) before separating. Per Ericson and colleagues, in analysing genomic DNA, confirmed that puffbirds and jacamars were sister groups and their place in Piciformes. The lineage is sometimes elevated to order level as Galbuliformes, first proposed by Sibley and Ahlquist in 1990. Taxonomy The following arrangement of taxa is based on Witt (2004).Witt, C.C.

Bucconidae
The puffbirds and their relatives in the family Bucconidae are tropical tree-dwelling insectivorous birds that are found from South America up to Mexico. Together with their closest relatives, the jacamars, they form a divergent lineage within the order Piciformes, though the two families are sometimes elevated to a separate order Galbuliformes. Lacking the iridescent colours of the jacamars, puffbirds are mainly brown, rufous or grey, with large heads, large eyes, and flattened bills with a hooked tip. Their loose, abundant plumage and short tails makes them look stout and puffy, giving rise to the English name of the family. The species range in size from the rufous-capped nunlet, at and , to the white-necked puffbird, at up to and . Taxonomy Puffbirds get their common name from their fluffy plumage. In Spanish, they have been nicknamed ''bobo'' ("dummy") from their propensity to sit motionless waiting for prey. American naturalist Thomas Horsfield defined the Bucconidae in ...

Galbulidae
The jacamars are a family, Galbulidae, of birds from tropical South and Central America, extending up to Mexico. The family contains five genera and 18 species. The family is closely related to the puffbirds, another Neotropical The Neotropical realm is one of the eight biogeographic realms constituting Earth's land surface. Physically, it includes the tropical terrestrial ecoregions of the Americas and the entire South American temperate zone.

Piciformes
Nine families of largely arboreal birds make up the order Piciformes (), the best-known of them being the Picidae, which includes the woodpeckers and close relatives. The Piciformes contain about 71 living genera with a little over 450 species, of which the Picidae make up about half. In general, the Piciformes are insectivorous, although the barbets and toucans mostly eat fruit and the honeyguides are unique among birds in being able to digest beeswax (although insects make up the bulk of their diet). Nearly all Piciformes have parrot-like zygodactyl feet—two toes forward and two back, an arrangement that has obvious advantages for birds that spend much of their time on tree trunks. An exception are a few species of three-toed woodpeckers. The jacamars aside, Piciformes do not have down feathers at any age, only true feathers. They range in size from the rufous piculet at 8 centimetres in length, and weighing 7 grams, to the toco toucan, at 63 centimetres long, and ...

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 ...
