Starlings are small to medium-sized passerinebirds in the familySturnidae, common name of Sturnid. The Sturnidae are named for the genus Sturnus, which in turn comes from the Latin word for starling, sturnus. The family contains 128 species which are divided into 36 genera. Many Asian species, particularly the larger ones, are called mynas, and many African species are known as glossy starlings because of their iridescentplumage. Starlings are native to Europe, Asia, and Africa, as well as northern Australia and the islands of the tropical Pacific. Several European and Asian species have been introduced to these areas, as well as North America, Hawaii, and New Zealand, where they generally compete for habitats with native birds and are considered to be invasive species. The starling species familiar to most people in Europe and North America is the common starling, and throughout much of Asia and the Pacific, the common myna is indeed common.
Starlings have strong feet, their flight is strong and direct, and they are very gregarious. Their preferred habitat is fairly open country, and they eat insects and fruit. Several species live around human habitation and are effectively omnivores. Many species search for prey such as grubs by "open-bill probing", that is, forcefully opening the bill after inserting it into a crevice, thus expanding the hole and exposing the prey; this behaviour is referred to by the German verb zirkeln (pronounced [ˈtsɪʁkl̩n]).[1]
Plumage of many species is typically dark with a metallic sheen. Most species nest in holes and lay blue or white eggs.
Starlings have diverse and complex vocalizations and have been known to embed sounds from their surroundings into their own calls, including car alarms and human speech patterns. The birds can recognize particular individuals by their calls and are the subject of research into the evolution of human language.[2]
Starlings are medium-sized passerines.[3] The shortest-bodied species is Kenrick's starling (Poeoptera kenricki), at 15cm (6in), but the lightest-weight species is Abbott's starling (Poeoptera femoralis), which is 34g (1+1⁄4oz). The largest starling, going on standard measurements and perhaps weight, is the Nias hill myna (Gracula robusta). This species can measure up to 36cm (14in), and in domestication they can weigh up to 400g (14oz). Rivaling the prior species in bulk if not dimensions, the mynas of the genus Mino are also large, especially the yellow-faced (M. dumontii) and long-tailed mynas (M. kreffti). The longest species in the family is the white-necked myna (Streptocitta albicollis), which can measure up to 50cm (19+1⁄2in), although around 60% in this magpie-like species is comprised by its very long tail.[4]
Less sexual dimorphism is seen in plumage, but with only 25 species showing such differences between the two sexes. The plumage of the starling is often brightly coloured due to iridescence; this colour is derived from the structure of the feathers, not from any pigment. Some species of Asian starling have crests or erectile feathers on the crest. Other ornamentation includes elongated tail feathers and brightly coloured bare areas on the face. These colours can be derived from pigments, or as in the Bali myna, structural colour, caused by light scattering off parallel collagen fibers. The irises of many species are red and yellow, although those of younger birds are much darker.[3]
Distribution, habitat and movements
The chestnut-tailed starling is a partial migrant over much of the east of its range, but its movements are poorly understood.
Starlings inhabit a wide range of habitats from the Arctic Circle to the Equator. The only habitats they do not typically occupy are very dry sandy deserts. The family is naturally absent from the Americas and from large parts of Australia, but it is present over the majority of Europe, Africa, and Asia. The genus Aplonis has also spread widely across the islands of the Pacific, reaching Polynesia, Melanesia, and Micronesia[3] (in addition one species in the genus Mino has reached the Solomon Islands[5]). Also, a species of this genus is the only starling found in northern Australia.[3]
Asian species are most common in evergreen forests; 39 species found in Asia are predominantly forest birds as opposed to 24 found in more open or human modified environments. In contrast to this, African species are more likely to be found in open woodlands and savannah; 33 species are open-area specialists compared to 13 true forest species. The high diversity of species found in Asia and Africa is not matched by Europe, which has one widespread (and very common) species and two more restricted species. The European starling is both highly widespread and extremely eclectic in its habitat, occupying most types of open habitat. Like many other starling species, it has also adapted readily to human-modified habitat, including farmland, orchards, plantations, and urban areas.[3]
The European starling was purposely introduced to North America in the 1870s through the 1890s by multiple acclimatisation societies, organizations dedicated to introducing European flora and fauna into North America for cultural and economic reasons.[6] A persistent story alleges that Eugene Schieffelin, chairman of the American Acclimatization Society, decided all birds mentioned by William Shakespeare should be in North America, leading to the introduction of the starling to the U.S.; however, this claim is more fiction than fact.[7][6] While Schieffelin and other members of the society did release starlings in Central Park in 1890, the birds had already been in the U.S. since at least the mid-1870s, and Schieffelin was not inspired to do so by Shakespeare's works.[6]
The starlings are generally a highly social family. Most species associate in flocks of varying sizes throughout the year. Murmuration is the flocking of starlings, including the swarm behaviour of their large flight formations.[8] These flocks may include other species of starlings and sometimes species from other families. This sociality is particularly evident in their roosting behaviour; in the nonbreeding season, some roosts can number in the thousands of birds.[3]
Mimic
Starlings imitate a variety of avian species and have a repertoire of about 15–20 distinct imitations. They also imitate a few sounds other than those of wild birds. The calls of abundant species or calls that are simple in frequency structure and show little amplitude modulation are preferentially imitated. Dialects of mimicked sounds can be local.[3]
Diet and feeding
Micronesian starlings have been observed feeding on the eggs of seabirds.Two starlings and an American robin (right) on grape arbor: The American robin is plucking a grape. Robins and starlings cause serious damage to ripening grapes in California and elsewhere.
The diets of the starlings are usually dominated by fruits and insects. Many species are important dispersers of seeds, in Asia and Africa, for example, white sandalwood and Indian banyan. In addition to trees, they are also important dispersers of parasiticmistletoes. In South Africa, the red-winged starling is an important disperser of the introducedAcacia cyclops. Starlings have been observed feeding on fermenting over-ripe fruit, which led to the speculation that they might become intoxicated by the alcohol.[3]
Laboratory experiments on European starlings have found that they have disposal enzymes that allow them to break down alcohol very quickly.[9] In addition to consuming fruits, many starlings also consume nectar. The extent to which starlings are important pollinators is unknown, but at least some are, such as the slender-billed starling of alpine East Africa, which pollinates giantlobelias.[3]
Systematics
This section needs to be updated. Please help update this article to reflect recent events or newly available information.(December 2019)
The starling family Sturnidae was introduced (as Sturnidia) by French polymathConstantine Samuel Rafinesque in 1815.[10][11] The starlings belong to the superfamily Muscicapoidea, together with thrushes, flycatchers and chats, as well as dippers, which are quite distant relatives, and Mimidae (thrashers and mockingbirds). The latter are apparently the Sturnidae's closest living relatives, replace them in the Americas, and have a rather similar but more solitary lifestyle. They are morphologically quite similar too—a partly albinistic specimen of a mimid, mislabelled as to suggest an Old World origin, was for many decades believed to represent an extinct starling (see Rodrigues starling for details).
The oxpeckers are sometimes placed here as a subfamily, but the weight of evidence has shifted towards granting them full family status as a more basal member of the Sturnidae-Mimidae group, derived from an early expansion into Africa.
Usually, the starlings are considered a family, as is done here. Sibley & Monroe[12] included the mimids in the family and demoted the starlings to tribe rank, as Sturnini. This treatment was used by Zuccon et al.[13] However, the grouping of Sibley & Monroe is overly coarse due to methodological drawbacks of their DNA-DNA hybridization technique and most of their proposed revisions of taxonomic rank have not been accepted (see for example Ciconiiformes). The all-inclusive Sturnidae grouping conveys little information about biogeography, and obscures the evolutionary distinctness of the three lineages. Establishing a valid name for the clade consisting of Sibley/Monroe's "pan-Sturnidae" would nonetheless be desirable to contrast them with the other major lineages of Muscicapoidea.
Starlings probably originated in the general area of East Asia, perhaps towards the southwestern Pacific, as inferred by the number of plesiomorphic lineages to occur there. Expansion into Africa appears to have occurred later, as most derived forms are found there. An alternative scenario would be African origin for the entire "sturnoid" group,[13] with the oxpeckers representing an ancient relict and the mimids arriving in South America. This is contradicted by the North American distribution of the most basal Mimidae.[13][14]
As the fossil record is limited to quite Recent forms, the proposed Early Miocene (about 25–20 Mya) divergence dates for the "sturnoids" lineages must be considered extremely tentative. Given the overall evidence for the origin of most Passeri families in the first half of the Miocene, it appears to be not too far off the mark, however.[13]
As of 2007,[update] recent studies[13][14] identified two major clades of this family, corresponding to the generally drab, often striped, largish "atypical mynas" and other mainly Asian-Pacific lineages, and the often smaller, sometimes highly apomorphictaxa which are most common in Africa and the Palearctic, usually have metallic coloration, and in a number of species also bright carotinoid plumage colors on the underside. Inside this latter group, there is a clade consisting of species which, again, are usually not too brightly colored, and which consists of the "typical" myna-Sturnus assemblage.
The Philippine creepers, a single genus of three species of treecreeper-like birds, appear to be highly apomorphic members of the more initial radiation of the Sturnidae.[13] While this may seem odd at first glance, their placement has always been contentious. In addition, biogeography virtually rules out a close relationship of Philippine creepers and treecreepers, as neither the latter nor their close relatives seem to have ever reached Wallacea, let alone the Philippines. Nonetheless, their inclusion in the Sturnidae is not entirely final and eventually, they may remain a separate family.
Genus sequence follows traditional treatments. This is apparently not entirely correct, with Scissirostrum closer to Aplonis than to Gracula, for example, and Acridotheres among the most advanced genera. Too few taxa have yet been studied as regards their relationships, however, thus a change in the sequence has to wait for further studies.
As of 2023, the review by Lovette & Rubenstein (2008) is the most recent work on the phylogeny of the group.[15] This taxonomy is also based on the order of the IOC.[16]
Genus Rhabdornis—Philippine creepers (four species)
Unresolved
The extinctMascarene starlings were formerly of uncertain relationships, but are now thought to belong to the Oriental-Australasian clade, being allied with the Bali myna.[16] However, while the two more recent species (Fregipilus and Necropsar) have been classified, the prehistoric Cryptopsar has not.
The mynas are a group of birds in the starling family (Sturnidae). This is a group of passerine birds which are native to Southern Asia, especially Afghanistan, India, Pakistan, Bangladesh, Nepal and Sri Lanka. Several species have been introduced to areas like North America, Australia, South Africa, Fiji and New Zealand, especially the common myna, which is often regarded as an invasive species.
The oxpeckers are two species of bird which make up the genus Buphagus, and family Buphagidae. The oxpeckers were formerly usually treated as a subfamily, Buphaginae, within the starling family, Sturnidae, but molecular phylogenetic studies have consistently shown that they form a separate lineage that is basal to the sister clades containing the Sturnidae and the Mimidae. Oxpeckers are endemic to the savanna of Sub-Saharan Africa.
The spotless starling is a passerine bird in the starling family, Sturnidae. It is closely related to the common starling, but has a much more restricted range, confined to the Iberian Peninsula, Northwest Africa, southernmost France, and the islands of Sicily, Corsica and Sardinia. It is largely non-migratory.
The brahminy starling or brahminy myna is a member of the starling family of birds. It is usually seen in pairs or small flocks in open habitats on the plains of the Indian subcontinent.
The chestnut-tailed starling, also called grey-headed starling and grey-headed myna is a member of the starling family. It is a resident or partially migratory species found in wooded habitats in India and Southeast Asia. The species name is after the distribution of a former subspecies in the Malabar region. While the chestnut-tailed starling is a winter visitor to peninsular India, the closely related resident breeding population with a white head is now treated as a full species, the Malabar starling.
The Bali myna, also known as Rothschild's mynah, Bali starling, or Bali mynah, locally known as jalak Bali, is a medium-sized, stocky myna, almost wholly white with a long, drooping crest, and black tips on the wings and tail. The bird has blue bare skin around the eyes, greyish legs and a yellow bill. Both sexes are similar. It is critically endangered and in 2020, fewer than 50 adults were assumed to exist in the wild.
The superb starling is a member of the starling family of birds. It was formerly known as Spreo superbus. They are long-lived birds that can live over 15 years in captivity.
The Malabar starling is a species of starling found in southwestern India. It was previously considered a subspecies of the chestnut-tailed starling.
The hoopoe starling, also known as the Réunion starling or Bourbon crested starling, is a species of starling that lived on the Mascarene island of Réunion and became extinct in the 1850s. Its closest relatives were the also-extinct Rodrigues starling and Mauritius starling from nearby islands, and the three apparently originated in south-east Asia. The bird was first mentioned during the 17th century and was long thought to be related to the hoopoe, from which its name is derived. Some affinities have been proposed, but it was confirmed as a starling in a DNA study.
Aplonis is a genus of starlings. These are essentially island species of Indonesia and Oceania, although some species' ranges extend to the Malay Peninsula, southern Vietnam and northeastern Queensland. The typical adult Aplonis starling is fairly uniformly plumaged in black, brown or dark green, sometimes with a metallic gloss. The eye ring is often distinctively coloured. Immatures of several species have dark streaked pale underparts.
Acridotheres is a genus of starlings, the "typical" mynas, which are tropical members of the family Sturnidae.
Lamprotornis is a large genus of glossy-starlings all of which occur in Africa south of the Sahara. They have glossy blue or green upper parts, which is due to hollow melanin granules arranged in a single layer near the feather barbule's surface. This unique arrangement led to some glossy starlings formerly placed in the genus Spreo being transferred to Lamprotornis, since they shared this feature.
Onychognathus is a genus of starlings, most of which are found in Africa.
Poeoptera is a genus of bird in the starling family. It contains three species, all live in forest habitats in Africa. These starlings nest in tree cavities, such as old woodpecker or barbet holes. One species, the narrow-tailed starling, nests in colonies. All are birds of the canopy, and their diet is mostly or entirely fruit. Males have a glossier appearance than females.
The white-headed starling, also known as the Andaman white-headed starling, is a species of starling in the family Sturnidae. It is found in wooded habitats of the Andaman and Nicobar Islands.
The black-winged myna is a species of starling in the family Sturnidae. The species is also known as the black-winged starling or the white-breasted starling. It is endemic to Indonesia. There are three recognised subspecies: the nominate race, which occurs across much of the island of Java; tricolor, which is restricted to south east Java; and tertius, which is found on Bali and possibly Lombok. The validity of the records on Lombok has been called into question, as there are only a few records and those may represent escapees from the caged-bird trade or natural vagrants. The species has often been assigned to the starling genus Sturnus, but is now placed in Acridotheres because it is behaviourally and vocally closer to the birds in that genus.
The black-collared starling is a species of starling in the family Sturnidae. Its plumage is black and white, with a black collar. It is found in southern China and most of mainland Southeast Asia, and has been introduced to Taiwan, Malaysia and Singapore. Its habitats include grassland, dry forest and human settlements. The International Union for Conservation of Nature (IUCN) has assessed it as being of least concern.
The white-shouldered starling is a species of bird in the starling family Sturnidae. It breeds in southern China and northern Vietnam; it winters in Southeast Asia.
Sturnia is a genus of Asian birds in the starling family Sturnidae. It is sometimes merged with Sturnus.
Agropsar is a genus of Asian birds in the family Sturnidae. It is sometimes merged with Sturnus or Sturnia
