Diversity
Roughly 140 families, 6,500 species

A passerine (/ˈpæsərn/) is any bird of the order Passeriformes (/ˈpæsərɪfɔːrmz/; 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,

Passeri (oscines or songbirds).[4][5] Passerines originated in the Southern Hemisphere around 60 million years ago.[6]

Most passerines are

that eat both insects and fruit or seeds.

The terms "passerine" and "Passeriformes" are derived from the scientific name of the house sparrow, Passer domesticus, and ultimately from the Latin term passer, which refers to sparrows and similar small birds.

Description

The order is divided into three suborders,

songs and other vocalizations, though some of them, such as the crows, do not sound musical to human beings. Some, such as the lyrebird, are accomplished mimics.[8] The New Zealand wrens are tiny birds restricted to New Zealand
, at least in modern times; they were long placed in Passeri.

Pterylosis or the feather tracts in a typical passerine

Most passerines are smaller than typical members of other avian orders. The heaviest and altogether largest passerines are the thick-billed raven[9] 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 is the short-tailed pygmy tyrant, at 6.5 cm (2.6 in) and 4.2 g (0.15 oz).[10]

Anatomy

The foot of a passerine has three toes directed forward and one toe directed backward, called

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
, 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.[11][12]

Most passerine birds have 12 tail feathers but the

treecreepers and woodcreeper have stiff tail feathers that are used as props during climbing.[14] Extremely long tails used as sexual ornaments are shown by species in different families. A well-known example is the long-tailed widowbird
.

Eggs and nests

The chicks of passerines are

parasitic cuckoos, which match the passerine host's egg. The vinous-throated parrotbill has two egg colors, white and blue, to deter the brood parasitic common cuckoo.[citation needed
]

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 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.[citation needed]

The Passeriformes contain several groups of

brood parasites such as the viduas, cuckoo-finches, and the cowbirds
.

Origin and evolution

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 the basis of morphological similarities that, it is now believed, are the result of

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.[a]

Advances in

paleobiogeographical data gradually are revealing a clearer picture of passerine origins and evolution that reconciles molecular affinities, the constraints of morphology, and the specifics of the fossil record.[16] 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.[5][6]

The initial diversification of passerines coincides with the separation of the southern continents in the

biogeographical mixing happens, with northern forms returning to the south, southern forms moving north, and so on.[3]

Perching bird

Passeriformes.[17] However, the material is too fragmentary and their affinities have been questioned.[20] Several more recent fossils from the Oligocene of Europe, such as Wieslochia, Jamna, Resoviaornis, and Crosnoornis,[21]
are more complete and definitely represent early passeriforms, although their exact affinities are not known.

Lillburnian, 19–16 mya).[22]

Early European passerines

Wieslochia fossil

In Europe, perching birds are not too uncommon in the fossil record from the Oligocene onward, but most are too fragmentary for a more definite placement:

  • Wieslochia (Early Oligocene of Frauenweiler, Germany)
  • Resoviaornis (Early Oligocene of Wola Rafałowska, Poland)
  • Jamna (Early Oligocene of Jamna Dolna, Poland)
  • Winnicavis (Early Oligocene of Lower Silesian Voivodeship, Poland)
  • Crosnoornis (Early Oligocene of Poland)
  • Passeriformes gen. et sp. indet. (Early Oligocene of Luberon, France) – suboscine or basal[b]
  • Passeriformes gen. et spp. indet. (Late Oligocene of France) – several suboscine and oscine taxa[24][19]
  • Passeriformes gen. et spp. indet. (Middle Miocene of France and Germany) – basal?[c]
  • Passeriformes gen. et spp. indet. (Sajóvölgyi Middle Miocene of Mátraszőlős, Hungary) – at least 2 taxa, possibly 3; at least one probably Oscines.[d]
  • Passeriformes gen. et sp. indet. (Middle Miocene of Felsőtárkány, Hungary) – oscine?[e]
  • Passeriformes gen. et sp. indet. (Late Miocene of Polgárdi, Hungary) – Sylvioidea (Sylviidae? Cettiidae?)[27]

That suboscines expanded much beyond their region of origin is proven by several fossils from Germany such as a presumed broadbill (

lagerstätten (<1.8 mya) yield numerous extant species, and many yield almost nothing but extant species or their chronospecies
and paleosubspecies.

Systematics and taxonomy

Acanthisitti

Tyranni – suboscines (16 families containing 1,356 species)

Passeri
– oscines (125 families containing 5,158 species)

Phylogenetic relationship of the suborders within the Passeriformes. The numbers are from the list published by the International Ornithologists' Union in January 2020.[1][30]

The Passeriformes is currently divided into three suborders:

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.[citation needed
]

Major "

monotypic with only one living species.[31] In the Passeri alone, a number of minor lineages will eventually be recognized as distinct superfamilies. For example, 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 them 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 a distinct super-family Certhioidea
.

Taxonomic list of Passeriformes families

Acanthisitti

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).[1] The order and the division into infraorders, parvorders, and superfamilies follows the phylogenetic analysis published by Carl Oliveros and colleagues in 2019.[30][g] The relationships between 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.[30]
