48-400: A raven is any of several larger-bodied passerine bird species in the genus Corvus . These species do not form a single taxonomic group within the genus. There is no consistent distinction between crows and ravens; the two names are assigned to different species chiefly based on their size. The largest raven species are the common raven and the thick-billed raven ; these are also
96-511: A tui -sized bird) and several bones of at least one species of saddleback -sized bird have recently been described. These date from the Early to Middle Miocene ( Awamoan to Lillburnian , 19–16 mya). In Europe, perching birds are not too uncommon in the fossil record from the Oligocene onward, belonging to several lineages: That suboscines expanded much beyond their region of origin
144-470: A clearer picture of passerine origins and evolution that reconciles molecular affinities, the constraints of morphology, and the specifics of the fossil record. The first passerines are now thought to have evolved in the Southern Hemisphere in the late Paleocene or early Eocene , around 50 million years ago. The initial diversification of passerines coincides with the separation of
192-483: A distinct super-family Certhioidea . This list is in taxonomic order, placing related families next to one another. The families listed are those recognised by the International Ornithologists' Union (IOC). The order and the division into infraorders, parvorders, and superfamilies follows the phylogenetic analysis published by Carl Oliveros and colleagues in 2019. The relationships between
240-469: A dozen and other species around five or six. The family Viduidae do not build their own nests, instead, they lay eggs in other birds' nests. The Passeriformes contain several groups of brood parasites such as the viduas , cuckoo-finches , and the cowbirds . The evolutionary history of the passerine families and the relationships among them remained rather mysterious until the late 20th century. In many cases, passerine families were grouped together on
288-399: A fruiting tree, they will not associate with them otherwise and will not stay with other species for long. Fruit is eaten while perched and not in the air, and birds-of-paradise are able to use their feet as tools to manipulate and hold their food, allowing them to extract certain capsular fruit. There is some niche differentiation in fruit choice by species and any one species will only consume
336-639: A group of ravens is "unkindness"; in practice, most people use the more generic "flock". Passerine and see text A passerine ( / ˈ p æ s ə r aɪ n / ) is any bird of the order Passeriformes ( / ˈ p æ s ə r ɪ f ɔːr m iː z / ; from Latin passer 'sparrow' and formis '-shaped') which includes more than half of all bird species. Sometimes known as perching birds , passerines generally have an anisodactyl arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes
384-710: A species outside New Guinea is Phonygammus , one representative of which is found in the extreme north of Queensland . The remaining species are restricted to New Guinea and some of the surrounding islands. Many species have very small ranges, particularly those with restricted habitat types such as mid-montane forest (like the black sicklebill ) or island endemics (like the Wilson's bird-of-paradise ). The majority of birds-of-paradise live in tropical forests, including rainforests , swamps, and moss forests , nearly all of them solitary tree dwellers. Several species have been recorded in coastal mangroves. The southernmost species,
432-482: Is currently divided into three suborders: Acanthisitti (New Zealand wrens), Tyranni , (suboscines) and Passeri (oscines or songbirds). The Passeri is now subdivided into two major groups recognized now as Corvides and Passerida respectively containing the large superfamilies Corvoidea and Meliphagoidea , as well as minor lineages, and the superfamilies Sylvioidea , Muscicapoidea , and Passeroidea but this arrangement has been found to be oversimplified. Since
480-906: Is more scant before the Pleistocene, from which several still-existing families are documented. Apart from the indeterminable MACN -SC-1411 (Pinturas Early/Middle Miocene of Santa Cruz Province, Argentina), an extinct lineage of perching birds has been described from the Late Miocene of California, United States: the Palaeoscinidae with the single genus Palaeoscinis . "Palaeostruthus" eurius (Pliocene of Florida) probably belongs to an extant family, most likely passeroidean . Acanthisitti – New Zealand wrens (1 family containing 7 species, only 2 extant) Tyranni – suboscines (16 families containing 1,356 species) Passeri – oscines (125 families containing 5,158 species) The Passeriformes
528-537: Is proven by several fossils from Germany such as a presumed broadbill ( Eurylaimidae ) humerus fragment from the Early Miocene (roughly 20 mya) of Wintershof , Germany, the Late Oligocene carpometacarpus from France listed above, and Wieslochia , among others. Extant Passeri super-families were quite distinct by that time and are known since about 12–13 mya when modern genera were present in
SECTION 10
#1732757219191576-442: Is the long-tailed widowbird . The chicks of passerines are altricial : blind, featherless, and helpless when hatched from their eggs. Hence, the chicks require extensive parental care. Most passerines lay colored eggs, in contrast with nonpasserines, most of whose eggs are white except in some ground-nesting groups such as Charadriiformes and nightjars , where camouflage is necessary, and in some parasitic cuckoos , which match
624-459: Is the short-tailed pygmy tyrant , at 6.5 cm (2.6 in) and 4.2 g (0.15 oz). The foot of a passerine has three toes directed forward and one toe directed backward, called anisodactyl arrangement. The hind toe ( hallux ) is long and joins the leg at approximately the same level as the front toes. This arrangement enables passerine birds to easily perch upright on branches. The toes have no webbing or joining, but in some cotingas ,
672-574: Is the large island of New Guinea ; all but two genera are found in New Guinea. Those other two are the monotypic genera Lycocorax and Semioptera , both of which are endemic to the Maluku Islands , to the west of New Guinea. Of the riflebirds in the genus Ptiloris , two are endemic to the coastal forests of eastern Australia , one occurs in both Australia and New Guinea, and one is only found in New Guinea. The only other genus to have
720-545: Is the largest order of birds and among the most diverse clades of terrestrial vertebrates , representing 60% of birds. Passerines are divided into three suborders : Acanthisitti (New Zealand wrens), Tyranni (composed mostly of South American suboscines), and Passeri (oscines or songbirds). Passerines originated in the Southern Hemisphere around 60 million years ago. Most passerines are insectivorous or omnivorous , and eat both insects and fruit or seeds. The terms "passerine" and "Passeriformes" are derived from
768-657: The Corvida and numerous minor lineages make up songbird diversity today. Extensive biogeographical mixing happens, with northern forms returning to the south, southern forms moving north, and so on. Perching bird osteology , especially of the limb bones, is rather diagnostic. However, the early fossil record is poor because passerines are relatively small, and their delicate bones do not preserve well. Queensland Museum specimens F20688 ( carpometacarpus ) and F24685 ( tibiotarsus ) from Murgon, Queensland , are fossil bone fragments initially assigned to Passeriformes . However,
816-573: The Epimachus sicklebills, Paradigalla, and the astrapias. The final clade includes the Cicinnurus and the Paradisaea birds-of-paradise. The exact limits of the family have been the subject of revision as well. The three species of satinbird (the genera Cnemophilus and Loboparadisea ) were treated as a subfamily of the birds-of-paradise, Cnemophilinae. In spite of differences in
864-636: The Old World warblers and Old World babblers have turned out to be paraphyletic and are being rearranged. Several taxa turned out to represent highly distinct lineages, so new families had to be established, some of theirs – like the stitchbird of New Zealand and the Eurasian bearded reedling – monotypic with only one living species. In the Passeri alone, a number of minor lineages will eventually be recognized as distinct superfamilies. For example,
912-400: The corvids . Birds-of-paradise range in size from the king bird-of-paradise at 50 g (1.8 oz) and 15 cm (5.9 in) to the curl-crested manucode at 44 cm (17 in) and 430 g (15 oz). The male black sicklebill , with its long tail, is the longest species at 110 cm (43 in). In most species, the tails of the males are larger and longer than those of
960-631: The crows , do not sound musical to human beings. Some, such as the lyrebird , are accomplished mimics. The New Zealand wrens are tiny birds restricted to New Zealand , at least in modern times; they were long placed in Passeri. Most passerines are smaller than typical members of other avian orders. The heaviest and altogether largest passerines are the thick-billed raven and the larger races of common raven , each exceeding 1.5 kg (3.3 lb) and 70 cm (28 in). The superb lyrebird and some birds-of-paradise , due to very long tails or tail coverts, are longer overall. The smallest passerine
1008-436: The family Paradisaeidae of the order Passeriformes . The majority of species are found in eastern Indonesia , Papua New Guinea , and eastern Australia . The family has 45 species in 17 genera . The members of this family are perhaps best known for the plumage of the males of the species, the majority of which are sexually dimorphic . The males of these species tend to have very long, elaborate feathers extending from
SECTION 20
#17327572191911056-445: The kinglets constitute a single genus with less than 10 species today but seem to have been among the first perching bird lineages to diverge as the group spread across Eurasia. No particularly close relatives of theirs have been found among comprehensive studies of the living Passeri, though they might be fairly close to some little-studied tropical Asian groups. Nuthatches , wrens , and their closest relatives are currently grouped in
1104-425: The paradise riflebird of Australia , lives in sub-tropical and temperate wet forests. As a group the manucodes are the most plastic in their habitat requirements; in particular, the glossy-mantled manucode , which inhabits both forest and open savanna woodland. Mid-montane habitats are the most commonly occupied habitat, with thirty of the forty species occurring in the 1000–2000 m altitudinal band. The diet of
1152-507: The scientific name of the house sparrow , Passer domesticus , and ultimately from the Latin term passer , which refers to sparrows and similar small birds. The order is divided into three suborders, Tyranni (suboscines), Passeri (oscines or songbirds), and the basal Acanthisitti . Oscines have the best control of their syrinx muscles among birds, producing a wide range of songs and other vocalizations, though some of them, such as
1200-402: The superb lyrebird has 16, and several spinetails in the family Furnariidae have 10, 8, or even 6, as is the case of Des Murs's wiretail . Species adapted to tree trunk climbing such as treecreepers and woodcreeper have stiff tail feathers that are used as props during climbing. Extremely long tails used as sexual ornaments are shown by species in different families. A well-known example
1248-518: The type genus by the English naturalist William John Swainson . For many years the birds-of-paradise were treated as being closely related to the bowerbirds . Today while both are treated as being part of the Australasian lineage Corvida , the two are now thought to be only distantly related. The closest evolutionary relatives of the birds-of-paradise are the crow and jay family Corvidae ,
1296-601: The basis of morphological similarities that, it is now believed, are the result of convergent evolution , not a close genetic relationship. For example, the wrens of the Americas and Eurasia , those of Australia , and those of New Zealand look superficially similar and behave in similar ways, yet belong to three far-flung branches of the passerine family tree; they are as unrelated as it is possible to be while remaining Passeriformes. Advances in molecular biology and improved paleobiogeographical data gradually are revealing
1344-450: The beak, wings, tail, or head. For the most part, they are confined to dense rainforest habitats. The diet of all species is dominated by fruit and to a lesser extent arthropods . The birds-of-paradise have a variety of breeding systems, ranging from monogamy to lek -type polygamy . A number of species are threatened by hunting and habitat loss . The family Paradisaeidae is introduced (as Paradiseidae) in 1825 with Paradisaea as
1392-403: The birds-of-paradise is dominated by fruit and arthropods, although small amounts of nectar and small vertebrates may also be taken. The ratio of the two food types varies by species, with fruit predominating in some species, and arthropods dominating the diet in others. The ratio of the two will affect other aspects of the behaviour of the species; for example, frugivorous species tend to feed in
1440-512: The corvoidean and basal songbirds. The modern diversity of Passerida genera is known mostly from the Late Miocene onward and into the Pliocene (about 10–2 mya). Pleistocene and early Holocene lagerstätten (<1.8 mya) yield numerous extant species, and many yield almost nothing but extant species or their chronospecies and paleosubspecies. In the Americas , the fossil record
1488-741: The described species were so rare, he examined many controversial specimens and, during the 1920s and 1930s, published several papers on his hypothesis. Many of the species described in the late 19th and early 20th centuries are now generally considered to be hybrids, though some are still subject to dispute; their status is not likely to be settled definitely without genetic examination of museum specimens, which will come soon in summer 2021 in North America, South America, Africa, Europe, Asia, and Australia, and some birds in an aviary in Central Park Zoo . Birds-of-paradise are closely related to

1536-465: The dimorphic species is typically drab to blend in with their habitat, unlike the bright attractive colours found on the males. Younger males of these species have female-like plumage, and sexual maturity takes a long time, with the full adult plumage not being obtained for up to seven years. This affords the younger males protection from predators of more subdued colours and also reduces hostility from adult males. The centre of bird-of-paradise diversity
1584-404: The families in the suborder Tyranni (suboscines) were all well determined but some of the nodes in Passeri (oscines or songbirds) were unclear owing to the rapid splitting of the lineages. Infraorder Eurylaimides : Old World suboscines Infraorder Tyrannides : New World suboscines Parvorder Furnariida Parvorder Tyrannida Relationships between living Passeriformes families based on
1632-1641: The family has been determined by Martin Irestedt and collaborators. Lycocorax – paradise-crows (2 species) Phonygammus – trumpet manucode Manucodia – manucodes (5 species) Pteridophora – King of Saxony bird-of-paradise Parotia – parotias (6 species) Seleucidis – twelve-wired bird-of-paradise Drepanornis – sicklebills (2 species) Semioptera – standardwing bird-of-paradise Lophorina – lophorinas (3 species) Ptiloris – riflebirds (4 species) Epimachus – sicklebills (2 species) Paradigalla – paradigallas (2 species) Astrapia – astrapias (5 species) Cicinnurus – King bird-of-paradise Diphyllodes – birds-of-paradise (2 species) Paradisornis – blue bird-of-paradise Paradisaea – birds-of-paradise (6 species) genus : Lycocorax genus : Manucodia genus : Phonygammus genus : Paradigalla genus : Astrapia genus : Parotia genus : Pteridophora genus : Lophorina genus : Ptiloris genus : Epimachus genus : Drepanornis genus : Cicinnurus genus : Diphyllodes genus : Semioptera genus : Seleucidis genus : Paradisaea Hybrid birds-of-paradise may occur when individuals of different species, that look similar and have overlapping ranges, confuse each other for their own species and crossbreed. When Erwin Stresemann realised that hybridisation among birds-of-paradise might be an explanation as to why so many of
1680-469: The females have larger bills than the males are more common, particularly in the insect-eating species. Plumage variation between the sexes is closely related to the breeding system. The manucodes and paradise-crow, which are socially monogamous, are sexually monomorphic . So are the two species of Paradigalla , which are polygamous. All these species have generally black plumage with varying amounts of green and blue iridescence . The female plumage of
1728-480: The females, the differences ranging from slight to extreme. The wings are rounded and in some species structurally modified on the males in order to make sound. There is considerable variation in the family with regard to bill shape. Bills may be long and decurved, as in the sicklebills and riflebirds, or small and slim like the Astrapias . As with body size, bill size varies between the sexes, although species where
1776-513: The forest canopy, whereas insectivores may feed lower down in the middle storey. Frugivores are more social than the insectivores, which are more solitary and territorial . Even the birds-of-paradise that are primarily insect eaters will still take large amounts of fruit. The family is overall an important seed disperser for the forests of New Guinea, as they do not digest the seeds. Species that feed on fruit will range widely searching for fruit, and while they may join other fruit-eating species at
1824-495: The genus Melampitta , also from New Guinea, have been linked with the birds-of-paradise, but their relationships remain uncertain, more recently being linked with the Australian mudnesters. The silktail of Fiji has been linked with the birds-of-paradise many times since its discovery, but never formally assigned to the family. Recent molecular evidence now places the species with the fantails . A genus level phylogeny of
1872-619: The largest passerine species. The term raven originally referred to the common raven ( Corvus corax ), the type species of the genus Corvus , which has a larger distribution than any other species of Corvus , ranging over much of the Northern Hemisphere . The modern English word raven has cognates in all other Germanic languages , including Old Norse (and subsequently modern Icelandic ) hrafn and Old High German (h)Raban , all of which descend from Proto-Germanic * hrabanaz . One collective noun for
1920-669: The material is too fragmentary and their affinities have been questioned. Several more recent fossils from the Oligocene of Europe, such as Wieslochia , Jamna , Resoviaornis , and Crosnoornis , are more complete and definitely represent early passeriforms, and have been found to belong to a variety of modern and extinct lineages. From the Bathans Formation at the Manuherikia River in Otago , New Zealand, MNZ S42815 (a distal right tarsometatarsus of
1968-536: The mid-2000s, studies have investigated the phylogeny of the Passeriformes and found that many families from Australasia traditionally included in the Corvoidea actually represent more basal lineages within oscines. Likewise, the traditional three-superfamily arrangement within the Passeri has turned out to be far more complex and will require changes in classification. Major " wastebin " families such as

2016-430: The monarch flycatchers Monarchidae , and the Australian mudnesters Struthideidae . A 2009 study examining the mitochondrial DNA of all species to examine the relationships within the family and to its nearest relatives estimated that the family emerged 24 million years ago, earlier than previous estimates. The study identified five clades within the family, and placed the split between the first clade, which contains
2064-525: The monogamous manucodes and paradise-crow , and all the other birds-of-paradise, to be 10 million years ago. The second clade includes the parotias and the King of Saxony bird-of-paradise . The third clade provisionally contains several genera, including Seleucidis , the Drepanornis sicklebills, Semioptera , Ptiloris, and Lophorina , although some of these are questionable. The fourth clade includes
2112-541: The mouth, foot morphology, and nesting habits they remained in the family until a 2000 study moved them to a separate family closer to the berrypeckers and longbills ( Melanocharitidae ). The same study found that the Macgregor's bird-of-paradise was actually a member of the large Australasian honeyeater family. In addition to these three species, a number of systematically enigmatic species and genera have been considered potential members of this family. The two species in
2160-518: The passerine host's egg. The vinous-throated parrotbill has two egg colors, white and blue, to deter the brood parasitic common cuckoo . Clutches vary considerably in size: some larger passerines of Australia such as lyrebirds and scrub-robins lay only a single egg, most smaller passerines in warmer climates lay between two and five, while in the higher latitudes of the Northern Hemisphere, hole-nesting species like tits can lay up to
2208-949: The phylogenetic analysis of Oliveros et al (2019). Some terminals have been renamed to reflect families recognised by the IOC but not in that study. The IOC families Alcippeidae and Teretistridae were not sampled in this study. Acanthisittidae (New Zealand wrens) Eurylaimidae (eurylaimid broadbills) Philepittidae (asites) Calyptomenidae (African and green broadbills) Pittidae (pittas) Sapayoidae (sapayoa) Melanopareiidae (crescent chests) Conopophagidae (gnateaters) Thamnophilidae (antbirds) Grallariidae (antpittas) Rhinocryptidae (tapaculos) Formicariidae (antthrushes) Scleruridae (leaftossers) Dendrocolaptidae (woodcreepers) Furnariidae (ovenbirds) Pipridae (manakins) Cotingidae (cotingas) Tityridae (tityras, becards) Bird-of-paradise 17 genera, 45 species The birds-of-paradise are members of
2256-509: The second and third toes are united at their basal third. The leg of passerine birds contains an additional special adaptation for perching. A tendon in the rear of the leg running from the underside of the toes to the muscle behind the tibiotarsus will automatically be pulled and tighten when the leg bends, causing the foot to curl and become stiff when the bird lands on a branch. This enables passerines to sleep while perching without falling off. Most passerine birds have 12 tail feathers but
2304-944: The southern continents in the early Eocene . The New Zealand wrens are the first to become isolated in Zealandia , and the second split involved the origin of the Tyranni in South America and the Passeri in the Australian continent . The Passeri experienced a great radiation of forms in Australia. A major branch of the Passeri, the parvorder Passerida , dispersed into Eurasia and Africa about 40 million years ago, where they experienced further radiation of new lineages. This eventually led to three major Passerida lineages comprising about 4,000 species, which in addition to
