18-475: Galbuliformes Fürbringer, 1888 Galbulae Vigors, 1825 Galbuli is one of the two suborders of the order Piciformes . It includes two families, Bucconidae (puffbirds) and Galbulidae (jacamars), both restricted to the Neotropics (in contrast to the more widespread suborder Pici ). It was thought the jacamars and puffbirds were not closely related to toucans and woodpeckers, but instead related to
36-494: A distinct Galbuliformes order. Analysis of nuclear genes confirms that they form a lineage of their own, but suggests that they are better treated as a suborder . The other families form another monophyletic group of suborder rank, but the barbets were determined to be paraphyletic with regard to the toucans and hence, the formerly all-encompassing Capitonidae have been split up. The woodpeckers and honeyguides are each other's closest relatives. According to some researchers,
54-418: 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 weighing 680 grams. All nest in cavities and have altricial young. The Galbulidae and Bucconidae are often separated into
72-483: A more basal position among the barbet-toucan clade altogether. On the other hand, they show some similarities to Trachyphonus in particular and have even been placed into this genus, but this move is not widely accepted. "CMC 152", a distal carpometacarpus similar to that of barbets and found at the Middle Miocene locality of Grive-Saint-Alban ( France ) was considered to differ from Capitonides in
90-486: A tree, and they usually lay between 2 and 4 eggs (except for the yellow-breasted barbet which lays up to 6), incubated for 13–15 days. Nesting duties are shared by both parents. There has been generally little interference by humans. Some of the species which require primary woodland are declining due to deforestation , occasionally to the benefit of close relatives. For example, the loss of highland woods in Kenya has seen
108-518: Is a family of birds also known as the African barbets . There are 42 species ranging from the type genus Lybius of forest interior to the tinkerbirds ( Pogoniulus ) of forest and scrubland . They are found throughout sub-Saharan Africa , with the exception of the far south-west of South Africa . The African terrestrial barbets, Trachyphoninae , range from the southern Sahara to South Africa . Members of one genus , Trachyphonus , are
126-480: Is based on Witt (2004). Piciformes For prehistoric taxa, see text Galbuliformes Fürbringer, 1888 Nine families of largely arboreal birds make up the order Piciformes / ˈ p ɪ s ɪ f ɔːr m iː z / , 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
144-492: Is eaten whole and indigestible material such as seed pits regurgitated later (often before singing ). Regurgitation does not usually happen in the nest (as happens with toucans ), although tinkerbirds do place sticky mistletoe seeds around the entrances of their nests, possibly to deter predators. Like other barbets, they are thought to be important agents in seed dispersal in tropical forests. As well as taking fruit, African barbets also take arthropod prey, gleaned from
162-475: Is fringed with bristles ; the tinkerbirds are smaller, ranging down to the red-rumped tinkerbird ( Pogoniulus atroflavus ) at 7 g (0.25 oz) and 9 cm (3.5 in). They are mainly solitary birds, eating insects and fruit. Figs and numerous other species of fruiting tree and bush are visited. An individual barbet may feed on as many as 60 different species in its range. They will also visit plantations and take cultivated fruit and vegetables. Fruit

Subfamily Lybiinae Subfamily Trachyphoninae It is not entirely resolved whether the Early to Middle Miocene genus Capitonides from Europe belongs to this family or the Asian barbets (now Megalaimidae ). Indeed, given that the prehistoric birds somewhat resembled a primitive toucan (without these birds' present autapomorphies ), they might occupy

#1732772530186216-717: The Pici. The modern families are known to exist since the mid-late Oligocene to early Miocene; consequently, the older forms appear to be more basal . A large part of Piciform evolution seems to have occurred in Europe where only Picidae occur today; perhaps even some now exclusively Neotropical families have their origin in the Old World . Order: PICIFORMES [REDACTED] Lybiidae Buccanodon Gymnobucco Lybius Pogonornis Pogoniulus Stactolaema Trachyphonus Tricholaema Lybiidae
234-585: 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
252-596: The branches and trunks of trees. A wide range of insects are taken, including ants, cicadas, dragonflies, crickets, locusts, beetles, moths and mantids. Scorpions and centipedes are also taken, and a few species will take small vertebrates such as lizards, frogs and geckos. The precise nesting details of many African barbets are not yet known, although peculiarly among the Piciformes , some sociable species will nest in riverbanks or termite nests. Like many members of their order, Piciformes, their nests are in holes bored into
270-874: The entire order Piciformes should be included as a subgroup in Coraciiformes . The phylogenetic relationship between the nine families that make up the order Piciformes is shown in the cladogram below. The number of species in each family is taken from the list maintained by Frank Gill , Pamela C. Rasmussen and David Donsker on behalf of the International Ornithological Committee (IOC).

288-842: The evolutionary history of the Piciformes has been hampered by poor understanding of the evolution of the zygodactyl foot. A number of prehistoric families and genera, from the Early Eocene Neanis and Hassiavis , the Zygodactylidae / Primoscenidae , Gracilitarsidae , Sylphornithidae , and " Homalopus " , to the Miocene "Picus" gaudryi and the Pliocene Bathoceleus are sometimes tentatively assigned to this order. There are some extinct ancestral Piciformes known from fossils which have been difficult to place but at least in part probably belong to
306-505: The most open-country species of barbets. The subfamily Lybiinae contains the African arboreal barbets. There are 37 species of Lybiinae in 6 genera . The phylogenetic relationship between the African barbets and the eight other families in the order Piciformes is shown in the cladogram below. The number of species in each family is taken from the list maintained by Frank Gill , Pamela C. Rasmussen and David Donsker on behalf of
324-530: 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 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. The following arrangement of taxa
