Streptopelia (collared doves and turtle doves) is a genus of 15 species of birds in the pigeon and dove family Columbidae native to the Old World in Africa, Europe, and Asia. These are mainly slim, small to medium-sized species. The upperparts tend to be buffy brown and the underparts are often a shade of pinkish-brown, and they have a characteristic black-and-white patch on the neck. They have cooing or purring songs, monotonous in some, restful and soothing in others. The genus divides into two groups, the collared dove group (11 species) with uniform upperparts and a black half-collar edged with white, and the turtle dove group (4 species) with patterned upperparts and a barred side panel on the neck. They range in size from the 20–23 cm red collared dove to the 33–35 cm oriental turtle dove. Most of the species are resident or disperse over short distances, but two (the European and Oriental turtle doves) are long-distance migrants breeding in temperate areas and wintering in the tropics. The sexes are not differentiated in most of the species, except for the red collared dove, where the males are orange-red with a greyish head, and the females a duller brown.[1]

As a group, this genus is highly successful; several species are abundant in a range of habitats in the tropics, with three species having a more extensive distribution into temperate areas as well. The Eurasian collared dove (Streptopelia decaocto) in particular has expanded naturally out of its original range of the warmer temperate regions from southeastern Europe to India to colonise the rest of Europe, reaching as far west as Great Britain by 1960 and Ireland soon after, and also east across northern China to Japan. It has also been introduced into the Americas where it has now colonised most of North America, Central America, and the Caribbean, and is still spreading rapidly. Some other species have been less successful in recent years, with two species listed by IUCN as Vulnerable.[1]

Taxonomy

[edit]

The genus Streptopelia was described in 1855 by the French ornithologist Charles Lucien Bonaparte.[2] The genus name comes from Ancient Greek στρεπτός (streptós), meaning "twisted, wearing a torc", and πέλεια (péleia) meaning "dove".[3] Also in 1855, the English zoologist George Robert Gray designated the type species as Streptopelia risoria, the Barbary dove.[4][5] Although Streptopelia risoria has been confirmed as a valid name by the International Commission on Zoological Nomenclature,[6] the Barbary dove is generally treated as a domesticated form of the African collared dove Streptopelia roseogrisea.[7]

from Grokipedia
Streptopelia is a genus of birds in the pigeon and dove family, Columbidae, comprising 15 to 18 species of small to medium-sized doves primarily native to Africa, Asia, and Europe. The genus name derives from Ancient Greek streptos meaning "collar" and peleia meaning "dove," reflecting the characteristic dark neck patch or ring often present in these species. These doves are typically slim-bodied with pale brown or gray upperparts, pinkish underparts, and a black-and-white or dark collar on the hindneck, though varies across . Their distribution shows highest diversity in (8–10 ), followed by (6–8 ) and Europe (2–3 ), with several introduced to and where they have established populations. Taxonomically, Streptopelia comprises three main clades within Columbidae, but phylogenetic studies indicate it may not be strictly monophyletic, with close relations to certain Columba and Nesoenas suggesting potential revisions. Notable members include the Eurasian collared-dove (S. decaocto), a successful that has rapidly expanded across since the 1980s, and the European turtle-dove (S. turtur), which is declining due to habitat loss and , highlighting conservation challenges for the genus. Overall, Streptopelia species are adaptable to open habitats like savannas, woodlands, and urban areas, feeding mainly on seeds and often perching in small groups while producing distinctive cooing calls.

Description

Morphology

Species of the genus Streptopelia are small to medium-sized doves, typically measuring 20–35 cm in length, with body weights ranging from 100–300 g depending on the species. For example, the (S. tranquebarica) is among the smallest at 20.5–23 cm and about 104 g, while the (S. orientalis) reaches up to 33–35 cm and 165–274 g. These doves exhibit a slim, slender build characterized by long tails that often comprise nearly half the total body length and rounded wings suited for agile, maneuverable flight. Key anatomical features include small heads, short straight bills that are slender and adapted for seed consumption, medium-length necks, and strong legs enabling ground-based foraging. Sexual dimorphism is generally minimal in Streptopelia, with males and females similar in appearance and size, though males are slightly larger in certain species such as the (S. decaocto), particularly in wing, tail, and tarsus measurements. Juveniles hatch with downy and possess shorter tails compared to adults, retaining these traits until fledging after about 12–20 days, when they develop more adult-like feathering (detailed further in Plumage and coloration).

Plumage and coloration

Species in the genus Streptopelia typically display plumage with buffy brown to grayish upperparts, pinkish to vinaceous underparts, and pale grayish heads, often accented by a characteristic black-and-white collar or half-collar on the hindneck. This collar, a diagnostic feature for many species, consists of a narrow black band bordered by white feathers, as seen in the Eurasian collared-dove (S. decaocto), where it forms a prominent rectangular patch on the nape against a pale sandy-brown body. In contrast, turtle dove species like the European turtle-dove (S. turtur) exhibit more patterned upperparts, with scaled or spotted designs of black, chestnut, and rufous fringes on the back and wings, creating a tortoiseshell-like effect. Plumage within the genus falls into two broad groups: relatively uniform and subdued tones in collared doves, such as the light gray body of the African collared-dove (S. roseogrisea) with pinkish underparts and a black collar, versus the more ornate, scaled patterns in turtle doves. Unique traits distinguish certain species, including the red orbital ring surrounding the eye in the (S. semitorquata), which contrasts with its dark mauve-pink to wine-red underparts and bluish-gray head. is subtle in most species, with males occasionally showing more vibrant rosy or wine-red tones on the underparts, as in the red collared-dove (S. tranquebarica), where females are plainer and browner. Juveniles generally resemble adults but possess duller coloration and a barred or scaly appearance due to pale fringes on the feathers, resulting in a grizzled effect; for example, young Eurasian collared-doves have a less defined collar and brownish iris, while juvenile European turtle-doves show rufous-gray coverts with pale terminal edges. These age-related differences fade as the birds undergo their first complete molt into adult plumage.

Taxonomy

Etymology

The genus Streptopelia was introduced by the French ornithologist in 1855, in his work Comptes Rendus Hebdomadaires des Séances de l'Académie des Sciences. The name is derived from streptós (στρεπτός), meaning "twisted" or "collared," and péleia (πελεία), meaning "dove," a reference to the narrow, collar-like black-and-white markings on the hindneck of many species in the . This etymological choice highlights a key morphological feature distinguishing these doves from related genera. The type species for Streptopelia was designated as Streptopelia risoria (originally described as Columba risoria by in 1758), which represents the African collared dove; this name was validated by the in 2008, superseding the junior synonym Streptopelia roseogrisea. Linnaeus's original description was based on a domestic form with a distinctive "giggling" call, but the wild progenitor is the African collared dove native to and parts of Arabia. The type species S. risoria was validated by ICZN in 2008 as the name for both the domestic variant and the wild African collared dove, with S. roseogrisea as a junior synonym. Common names for species in this genus reflect both vocalizations and plumage. The term "turtle dove," applied to several Streptopelia species such as the (S. turtur), originates from the Latin turtur, an onomatopoeic imitation of the bird's soft, purring cooing call, which entered as turtla or turtur. Similarly, "collared dove" derives directly from the visible neck collar, a feature prominent in species like the (S. decaocto), with the earliest recorded use in English dating to 1802. Certain species names within the genus also carry etymological significance tied to or calls. For instance, the specific epithet decaocto of the is a Latinization of the Greek for "eighteen" (deka for ten and oktō for eight), stemming from a Balkan folktale in which a servant girl named Decaocto is transformed into a dove whose mournful song evokes the number eighteen, symbolizing her endless toil. This naming, originally proposed by Johann Frivaldszky in , underscores historical cultural associations with the bird's repetitive vocalizations.

Classification history

The genus Streptopelia was introduced by in 1855 in Comptes Rendus Hebdomadaires des Séances de l'Académie des Sciences, with further details in his Conspectus Generum Avium, initially encompassing 10 species of small to medium-sized doves primarily from the . The type species was subsequently designated as Streptopelia risoria (the or ringed turtle-dove) by later that year. Throughout the late 19th and 20th centuries, the underwent expansions as additional from and were incorporated, reflecting increased ornithological and collection efforts in those regions. This period saw debates over the inclusion of taxa such as the (Streptopelia chinensis, now in Spilopelia), which exhibited morphological differences from core Streptopelia members but were retained in the genus due to perceived affinities. A pivotal revision occurred in 2001 with a molecular phylogenetic by Johnson, Weckstein, and Meyer, which revealed Streptopelia to be paraphyletic as traditionally defined; the study proposed separating the spotted and into the resurrected genus Spilopelia and transferring the to Nesoenas to restore within Streptopelia. These changes were gradually adopted in major checklists. In the , further refinements included taxonomic splits for certain African populations, such as the recognition of distinct boundaries in taxa like the white-winged collared dove (S. reichenowi), based on vocal and evidence. As of version 15.1 (2025), the International Ornithological Committee (IOC) World Bird List recognizes 16 in Streptopelia, reflecting these historical and molecular-informed adjustments, including recent splits such as S. dusumieri. The genus is currently placed in the subfamily Columbinae within the family .

Phylogenetic relationships

The genus Streptopelia is monophyletic following taxonomic revisions that excluded paraphyletic elements (such as taxa now in Spilopelia and Nesoenas), as confirmed by subsequent phylogenetic analyses of nuclear and sequences resolving its coherence within . Within Streptopelia, two primary clades are recognized: a basal group encompassing the turtle doves (e.g., the S. turtur complex, including species like the S. turtur and rufous turtle dove S. orientalis), which originated in and , and a derived group comprising the collared doves (e.g., the S. decaocto complex, including the S. decaocto and African collared dove S. risoria), characterized by radiations primarily in . These clades reflect an early divergence pattern, with the turtle dove group representing ancestral forms adapted to diverse habitats and the collared dove group showing more recent expansions and morphological specializations, such as enhanced vocal and traits. The S. turtur clade occupies a basal position in the genus's phylogeny, supported by genetic distances and shared morphological features like scaled neck patterns, while the S. decaocto clade exhibits higher diversification rates linked to ecological . Recent splits, such as S. xanthocycla (Burmese collared dove) from S. decaocto (2024), further refine these relationships based on vocal and genetic evidence. The genus Streptopelia is sister to Spilopelia (spotted doves, formerly included in Streptopelia) and Macropygia (cuckoo-doves), forming a closely related assemblage within the columbids based on shared mitochondrial and nuclear markers. This relationship underscores a common evolutionary history involving dispersal across , with Spilopelia species like the spotted dove S. chinensis showing intermediate genetic affinities. estimates place the origin of Streptopelia in the , approximately 10-15 million years ago, coinciding with climatic shifts that facilitated avian radiations in the , while much of the intra-generic , including formations, occurred during the Pleistocene amid glacial cycles and habitat fragmentation. Evidence of rare hybridization exists within Streptopelia, particularly between closely related species in the collared dove clade, such as S. decaocto and S. risoria (African collared dove), where hybrids have been documented in overlapping ranges like the , often displaying intermediate and vocal traits but limited . These events are infrequent and typically confined to areas of human-mediated introduction, suggesting strong reproductive barriers despite phylogenetic proximity.

Distribution and habitat

Geographic range

The genus Streptopelia is native to the , with its 15 species distributed across , , , and adjacent regions including parts of and the . In , the range is limited primarily to the western Palearctic, where species such as the European turtle-dove (S. turtur) occur as breeders and migrants across central and , extending into the . The highest is concentrated in , home to approximately eight native species, including the widespread (S. capicola), which inhabits sub-Saharan savannas and woodlands from northward to the . In , Streptopelia extend from the through the and to and the , encompassing about six to eight such as the red collared-dove (S. tranquebarica) and the Philippine collared-dove (S. dusumieri). Areas of high species overlap and diversity include , where multiple congeners coexist, and the , supporting a rich assemblage of forms adapted to varied landscapes. Several Streptopelia species have established introduced populations outside their native ranges, often facilitated by human transport. The Eurasian collared-dove (S. decaocto) was introduced to via escapes in during the 1970s, subsequently expanding rapidly across the , southern , and , with an estimated population exceeding 8 million individuals by the . This species has also been introduced to various islands, Pacific locales including (where the Philippine collared-dove has likewise been established but is declining), and other regions.

Habitat preferences

Species of the genus Streptopelia primarily occupy open habitats such as woodlands, savannas, farmlands, and semi-arid scrublands, while generally avoiding dense forest interiors. These environments provide ample ground cover for foraging and scattered trees or shrubs for perching and nesting, allowing the doves to exploit seed-rich areas without heavy vegetative obstruction. For instance, the Eurasian collared-dove (S. decaocto) thrives in agricultural fields and suburban open spaces, reflecting the genus's affinity for landscapes modified by human activity. Adaptations to these habitats include ground-nesting in grassy or low-vegetation areas for certain species, which facilitates quick access to feeding grounds, as observed in the eastern turtle-dove (S. orientalis) and (S. senegalensis). Additionally, many Streptopelia doves on artificial structures like telegraph wires and fence posts in human-altered landscapes, enhancing their mobility across fragmented habitats. Altitudinal preferences span from to high elevations, with montane species like the dusky turtle-dove (S. lugens) inhabiting forests up to 3,200 m. Access to water is a critical factor, especially in arid regions, where species such as the mourning collared-dove (S. decipiens) and African collared-dove (S. roseogrisea) remain within approximately 10 km of rivers, watering holes, or riparian thickets to meet hydration needs. Urban tolerance varies but is pronounced in adaptable taxa; the (S. capicola), for example, flourishes in city parks, gardens, and suburban zones across , often coexisting with dense human populations.

Behavior and ecology

Diet and feeding

Species in the genus Streptopelia are primarily granivorous, with seeds from grasses, cereals, and weeds forming the core of their diet. For instance, in a study in southern , wild seeds were present in over 65% of European turtle doves (S. turtur), including important sources such as those of Echium plantagineum and Amaranthus deflexus, supplemented by cultivated cereals like and . Similarly, the (S. decaocto) consumes mostly seeds and grains including buck, rye, , oats, , corn, , millet, and sunflower seeds. The ring-necked dove (S. capicola) feeds on seeds of grasses, cereal grains, lupins, milkweeds, acacias, and pines, often raiding crops in agricultural areas. Supplementary foods include , snails, and berries, which provide essential proteins and are more prominent during the breeding season when energy demands rise. Termites, caterpillars, and flying are occasionally taken by like the vinaceous dove (S. vinacea), while the dusky turtle dove (S. lugens) incorporates and molluscs alongside weed seeds, cereals, sunflowers, and berries. These additions help meet nutritional needs, particularly for growing young, though adults remain seed-dominant. In preferred open ground , such as weedy fields or farmlands, these doves exploit diverse seed sources while briefly referencing habitat preferences for efficiency. Foraging typically involves ground pecking in pairs or small flocks, with birds collecting directly from the or low ; larger flocks form where resources abound, such as in fields. Species like the also pick s from feeders or shrubs and ingest grit to aid . Daily foraging peaks in the early morning and late afternoon, aligning with cooler temperatures and availability. is consumed frequently, often at dawn and dusk, via a unique sucking method that allows continuous intake without tilting the head, reducing exposure to predators.

Breeding biology

Breeding in the Streptopelia varies by geographic region and , with tropical populations often exhibiting year-round reproduction influenced by local rainfall and food availability, as seen in the (S. capicola) in where breeding occurs in all months. In contrast, temperate-zone like the (S. turtur) breed primarily from April to August, while the Eurasian collared-dove (S. decaocto) nests from February to October, extending year-round in warmer climates. These patterns align with seasonal resource peaks, enabling multiple broods—typically 2–4 per year, though up to 6 in favorable conditions—to maximize reproductive output. Nests are characteristically flimsy platforms of twigs, grasses, and roots, loosely constructed and often unlined, situated in trees, shrubs, or occasionally on artificial structures at heights of 2–10 m to reduce predation risk. For instance, in the , mean nest height is about 2.3 m in scrub habitats, while Eurasian collared-doves place nests higher, averaging 3.5–12.5 m in trees. Pairs may reuse existing nests or build new ones for successive broods, with construction taking 2–4 days and both sexes contributing materials. Clutches consist of 2 smooth, white eggs, occasionally 1 or 3, laid 1–2 days apart; incubation lasts 14–18 days and is shared biparentally, with males typically covering the daytime shift and females the night. Upon , altricial chicks are brooded continuously for the first few days and fed regurgitated —a nutrient-rich produced by both parents in the lining—transitioning to seeds after about a week. Chicks after 14–20 days, remaining dependent on parents for feeding and protection for another 1–2 weeks. In the wild, Streptopelia doves typically live 5–10 years, though averages are lower (3–6 years) due to high annual mortality from predation and environmental factors; their elevated reproductive rate, with multiple broods producing 4–12 fledglings annually per pair, compensates for these losses to sustain populations.

Migration patterns

Within the genus Streptopelia, migration patterns vary significantly among species, with most African and Asian taxa exhibiting sedentary or short-distance dispersive behaviors, while Palearctic species such as the (S. turtur) undertake long-distance migrations. The (S. orientalis) shows partial migratoriness, with northern populations, including those in the and northern , moving southward to peninsular , the , and southern during winter, though southern populations remain resident. The follows a looping migration route, breeding across central and , the , and before traveling over 4,000 km to wintering grounds in the of , particularly in , , and ; return migration often shifts eastward through the . In contrast, the intra-Asian movements of the involve shorter distances, typically southward along continental routes without crossing major barriers like the . Migration in Streptopelia is primarily triggered by photoperiod changes signaling seasonal shifts, combined with declining availability and adverse weather conditions that reduce breeding ground resources. Many undertake nocturnal flights to avoid predation and thermal constraints, with the capable of covering up to 700 km in a single night. The (S. decaocto), originally from , exhibits dispersive rather than true migratory behavior following its introduction to and , with young birds undertaking irregular long-distance movements that have facilitated rapid range expansions across continents. These patterns expose migratory Streptopelia populations to heightened vulnerability at bottlenecks, such as key stopover sites in the Mediterranean and , where concentrated passages amplify risks from habitat degradation and illegal hunting.

Vocalizations and displays

Streptopelia doves produce a variety of vocalizations primarily consisting of soft cooing calls that serve as key communicative signals. The primary call across the is a repetitive, low-pitched coo, often described as "turr-turr" or "coo-coo," which functions in territory defense and mate attraction. In the (Streptopelia decaocto), this manifests as a distinctive three-note "hoo-HOO-hoo" or "deca-octo" pattern, reflecting its species name and produced via a source-filter mechanism that yields pure-tonal sounds with harmonic overtones. These coos exhibit species-specific variations in temporal structure, such as and frequency jumps, enabling discrimination between closely related taxa. Courtship displays in Streptopelia integrate vocal and visual elements, with males performing motions accompanied by bow-coos—short-range variants of the primary -coo—while spreading their wings and fanning their tails on the ground or to attract females. Aerial pursuits, including arc-shaped flights, often follow, where males chase potential mates while emitting coos to escalate signaling intensity, particularly in the presence of competitors. These multimodal displays peak during breeding seasons, combining acoustic purity with visual elaboration to facilitate pair formation. Alarm and contact calls provide additional acoustic cues for immediate threats or social maintenance. When alarmed or excited, individuals emit sharp, nasal notes such as a loud "hwaah" or "chuck," signaling potential danger and often preceding flight or defensive posturing. Softer purring or nest coos, used for and pair bonding, occur during close-range interactions like nesting, contrasting the bolder perch-coos. The acoustic functions of these vocalizations emphasize territorial advertisement and reproductive signaling, with cooing activity showing diurnal patterns that peak at dawn and dusk, such as between 0800–1000 and 1600–1800 hours in species like the (Streptopelia turtur). This timing aligns with heightened male-male competition and female responsiveness, enhancing signal efficacy in semi-open habitats. Species variations in vocalizations highlight adaptive divergence within the genus; for instance, the European turtle dove's coos feature a more melodic, rolling with trill-type at about 25 cycles per second, differing from the repetitive, minimally modulated coos of the . Such differences aid in recognition and reduce interspecific interference, as demonstrated by perceptual tuning to specific and duration cues.91552-5)

Conservation

Major threats

The genus Streptopelia faces significant anthropogenic pressures that threaten its persistence across diverse ranges, particularly in species reliant on open woodlands and farmlands. Habitat loss, driven by agricultural intensification and , has led to substantial declines in suitable breeding and areas, such as the reduction of hedgerows and scrublands essential for nesting and collection. For instance, in , populations of the (S. turtur) have experienced long-term declines of up to 78% since 1980 due to these land-use changes, which fragment and degrade open woodland habitats preferred by multiple Streptopelia , though recent data indicate a 40% increase in Western European populations from 2021 to 2024 following conservation measures (as of 2025). Hunting represents a direct mortality , especially during migration, where legal and illegal shooting targets migratory species like the . Estimates indicate that 2–4 million individuals of this species were legally harvested annually along the western European (pre-2022), with illegal adding unquantified pressure that exacerbates population declines across the ; however, a temporary hunting moratorium (2022–2024) and subsequent strict quotas have reduced this impact. Climate change further compounds vulnerabilities by altering patterns, which disrupt availability and breeding success in wintering and breeding grounds. In western , variable rainfall linked to climatic shifts has reduced survival rates in S. turtur by affecting resources in the , a pattern that likely impacts other Streptopelia dependent on seasonal production. Competition and predation pose additional risks, particularly from introduced predators and invasive congeners. Domestic cats (Felis catus) prey on ground-foraging Streptopelia species, with the Eurasian collared dove (S. decaocto) frequently recorded as a victim in urban and suburban settings, increasing nest failure rates. Invasive relatives, such as the African collared dove (S. roseogrisea), compete for nesting sites and food in expanding ranges, as observed in Mexico where native species face displacement. Pesticide use in intensive indirectly threatens Streptopelia by diminishing populations, a critical protein source for provisioning chicks. In farmland birds like the , which feed nestlings primarily on , neonicotinoid pesticides reduce prey abundance, leading to lower chick survival and contributing to broader genus-wide declines in agricultural landscapes.

Species statuses

Of the 17 species in the genus Streptopelia, 16 are classified as Least Concern on the , while the European turtle-dove (S. turtur) is listed as Vulnerable due to ongoing population declines. The Vulnerable status of the European turtle-dove reflects a rapid decline across its range, with European populations reduced by approximately 78% since 1980, driven primarily by habitat degradation and unsustainable hunting. Population trends vary across the genus, with migratory showing declines attributed to pressure and loss, while more adaptable urban remain stable or increasing. For instance, the Oriental turtle-dove (S. orientalis) exhibits a decreasing trend despite its large range, linked to overharvest in parts of . In contrast, the (S. capicola) has increasing numbers, benefiting from its tolerance of human-modified environments across . Similarly, the Eurasian collared-dove (S. decaocto) has expanded rapidly in recent decades, with populations growing in both native and introduced ranges. The white-winged collared-dove (S. reichenowi) was previously assessed as Near Threatened but was uplisted to Least Concern in the 2024 IUCN update following improved data on its stable populations in . Conservation efforts focus on mitigating threats to declining , particularly through regulated and . Recent adaptive for the European turtle-dove includes strict quotas, such as a 1.5% bag limit in Western countries to ensure sustainable levels, contributing to a 40% population increase in from 2021 to 2024 following a temporary ban (as of 2025). In , where many Streptopelia winter, initiatives emphasize restoration, including the protection and enhancement of riparian forests in the , which serve as critical foraging and roosting sites for migrants like the European turtle-dove. Monitoring of Streptopelia species relies on assessments by , which compile data from , national surveys, and satellite tracking to inform IUCN evaluations and track trends. These efforts have facilitated recent status improvements, such as for the white-winged collared-dove, and guide ongoing actions to address declines in vulnerable taxa.
