Lapwings (subfamily Vanellinae) are any of various ground-nesting birds (family Charadriidae) akin to plovers and dotterels. They range from 10 to 16 inches (25 to 41 cm) in length.
The traditional terms "plover", "lapwing", and "dotterel" do not correspond exactly to current taxonomic models; thus, several of the Vanellinae are often called plovers, and one a dotterel, while a few of the "true" plovers (subfamily Charadriinae) are known colloquially as lapwings. In general, a lapwing can be thought of as a larger plover.
In Europe's Anglophone countries, lapwing refers specifically to the northern lapwing, the only member of this group to occur in most of the continent and thus the first bird to go by the English name lapwing (also known as peewit or pyewipe).
In the fanciful taxonomy promoted by medieval courtesy books, a group of lapwings was called a "deceit".[1]
Systematics
[edit]While authorities generally agree that there are approximately 25 species of Vanellinae, classifications within the subfamily remain confused. Some workers[who?] have gone so far as to group all the "true" lapwings (except the red-kneed dotterel) into the single genus Vanellus. Current consensus favors a more moderate position, but it is unclear which genera to split. The Handbook of Birds of the World provisionally places all Vanellinae in Vanellus except the red-kneed dotterel, which is in the monotypic Erythrogonys. Its plesiomorphic habitus resembles that of plovers, but details like the missing hallux (hind toe) are like those of lapwings: it is still not entirely clear whether it is better considered the most basal plover or lapwing.[2] The IOC also recognizes a monotypic genus Hoploxypterus for the pied plover.
Many coloration details of the red-kneed dotterel also occur here and there among the living members of the main lapwing clade. Its position as the most basal of the living Vanellinae or just immediately outside it thus means that their last common ancestor – or even the last common ancestor of plovers and lapwings – almost certainly was a plover-sized bird with a black crown and breast-band, a white feather patch at the wrist, no hallux, and a lipochromic (probably red) bill with a black tip. Its legs were most likely black or the color of the bill's base.[3]
Evolution
[edit]The fossil record of the Vanellinae is scant and mostly recent in origin; no Neogene lapwings seem to be known. On the other hand, it appears as if early in their evolutionary history the plovers, lapwings and dotterels must have been almost one and the same, and they are hard to distinguish osteologically even today. Thus, since the Red-kneed Dotterel is so distinct that it might arguably be considered a monotypic subfamily, reliably dating its divergence from a selection of true lapwings and plovers would also give a good idea of charadriid wader evolution altogether.
A mid-Oligocene – c.28 mya (million years ago) – fossil from Rupelmonde in Belgium has been assigned to Vanellus, but even if the genus were broadly defined, it is entirely unclear if the placement is correct. Its age ties in with the appearance of the first seemingly distinct Charadriinae at about the same time, and with the presence of more basal Charadriidae a few million years earlier. However, the assignment of fragmentary fossils to Charadriinae or Vanellinae is not easy. Thus, it is very likely that the charadriid waders originate around the Eocene-Oligocene boundary – roughly 40–30 mya – but nothing more can be said at present. If the Belgian fossil is not a true lapwing, there are actually no Vanellinae fossils known before the Quaternary.[4]
The Early Oligocene fossil Dolicopterus[5] from Ronzon, France may be such an ancestral member of the Charadriidae or even the Vanellinae, but it has not been studied in recent decades and is in dire need of review.[6]
Apart from the prehistoric Vanellus, the extinct lapwing genus Viator has been described from fossils. Its remains were found in the tar pits of Talara in Peru and it lived in the Late Pleistocene. Little is known of this rather large lapwing; it may actually belong in Vanellus.[7]
The remaining Charadrii are highset or chunky birds, larger than many of the scolopacid waders. The evolutionary trend regarding the Charadriidae – which make up most of the diversity of the Charadrii – thus runs contrary to Cope's Rule.[3]

Physical characteristics
Lapwings, members of the genus Vanellus, are medium to large plovers characterized by rounded bodies, short tails, and long legs adapted for wading in wetlands and soft soils.[2][4] They typically measure 25–40 cm in length and weigh 100–400 g, with representative examples including the Northern Lapwing (V. vanellus) at 28–31 cm and 128–330 g, the Red-wattled Lapwing (V. indicus) at 32–35 cm and 110–230 g, and the Southern Lapwing (V. chilensis) at 35–37 cm and 255–277 g.[5][6][7] A defining feature is the characteristic crest on the head, which varies in length and shape across species; for instance, the Northern Lapwing possesses a long, wispy crest, while the Crowned Lapwing (V. coronatus) features a distinctive black crown encircled by a white band.[2][8] Their upperparts often exhibit iridescent sheens in greens, bronzes, and purples, complemented by bold facial patterns such as black-and-white heads and contrasting breast bands.[2][9] The bill is short and straight or slightly upturned, suited for probing soil, and the wings are broad and rounded, enabling the erratic, tumbling flight typical of the genus.[2][10] Sexual dimorphism is minimal, with little difference in plumage coloration between males and females, though males often develop longer crests during the breeding season.[11][9] Plumage varies seasonally, appearing duller in non-breeding adults with brownish tones replacing black markings, while juveniles exhibit paler overall coloration, reduced iridescence, buff fringes on feathers, and a shorter or absent crest.[12][13] Representative species illustrate these traits: the Northern Lapwing features metallic green upperparts, white underparts, and a black breast band.[2] The Crowned Lapwing displays a distinctive black crown encircled by white, brown upperparts, white underparts, and yellow legs.[8][4]Vocalizations and displays
Lapwings employ a variety of vocalizations and visual displays to communicate, defend territories, attract mates, and protect offspring. The Northern Lapwing (Vanellus vanellus) is renowned for its shrill, repetitive "pee-wit" call, often rendered as "did-he-do-it," which serves as a territorial and display call during breeding season.[14] Alarm calls in this species include sharp "kree-ik" notes to signal ground threats, while softer whistling contact calls facilitate communication within flocks or family groups.[1] These vocalizations are simple and repetitive, with acoustic analyses revealing up to 24 distinct call types varying in duration, frequency, and bandwidth for different contexts.[15] Visual displays complement these calls, enhancing communication effectiveness. During territory defense, lapwings perform slow, deliberate wing-flapping flights that showcase their broad wings, often accompanied by the "pee-wit" call to advertise presence.[1] On the ground, individuals engage in scraping behaviors with wings raised to delineate territories or during aggressive encounters, where the crest is erected in a confrontational "erect attitude" alongside retracted necks and fluffed breast feathers.[16] Distraction displays, particularly by males, involve feigned injury such as dragging a "broken" wing or short dashes to lure predators away from nests, combining visual deception with accompanying calls to indicate extreme danger.[1] Courtship rituals integrate both acoustic and visual elements for pair formation. Males execute tumbling flights, characterized by wobbling, zigzagging, rolling, and diving maneuvers while emitting mating calls, often before sunrise, at noon, or sunset.[14] Once paired, duets feature synchronized head-bobbing, bowing, and scraping on the ground, with vocalizations reinforcing the bond.[1] Vocalizations vary across lapwing species, reflecting adaptations to different environments. The Southern Lapwing (Vanellus chilensis) produces louder, more aggressive "tero-tero-tero-tero" calls day and night, primarily for territory defense and pair interactions.[17] In contrast, the Red-wattled Lapwing (Vanellus indicus) is notable for its nocturnal territorial calls, described as scolding "did-he-do-it" phrases, which alert to intruders and maintain vigilance in low-light conditions.[18] These signals play key roles in social structure. Contact and all-clear calls help maintain flock cohesion during migration and regroup young after threats, while displays effectively deter intruders from breeding territories.[1]Taxonomy
Etymology
The common name "lapwing" originates from the Old English term hlæpewince, a compound of hlēapan ("to leap") and wince ("to waver" or "flicker"), which evokes the bird's characteristic irregular, loping flight and wavering movements.[19] This name has persisted through Middle English as lapwynge or similar variants, reflecting its onomatopoeic and descriptive roots tied to the bird's aerial behavior.[20] Additionally, lapwings are commonly known as "peewit" or "pewit" in English-speaking regions, derived from the 16th century as an imitation of the bird's shrill, repetitive alarm call resembling "pee-wit."[21] The scientific genus name Vanellus was coined from the Medieval Latin vanellus, a diminutive form of vannus ("winnowing fan" or "winnowing basket"), alluding to the lapwing's broad, fanning tail or the fan-like spread of its wings during flight.[22] This nomenclature highlights the bird's distinctive morphology, with the term first applied systematically in ornithology to capture its elegant, fan-shaped features. The Northern Lapwing (Vanellus vanellus) was initially described by Carl Linnaeus in 1758 as Tringa vanellus in his Systema Naturae, placing it within the sandpiper genus Tringa based on early classifications of waders. The genus Vanellus was formally established shortly thereafter by Mathurin Jacques Brisson in 1760, separating lapwings into their own taxonomic group to better reflect their unique traits.[23] In various regions, lapwings bear alternative common names influenced by their appearance or vocalizations, such as "plover" due to their affiliation with the Charadriidae family of plovers. Culturally, the Red-wattled Lapwing (Vanellus indicus) is known as "titeeri" in Hindi and other Indian languages, mimicking its loud, tinkling calls that serve as territorial warnings.[24] Taxonomic revisions have seen several lapwing species reclassified into Vanellus over time, driven by morphological analyses; for instance, some African and Asian taxa previously assigned to genera like Hoplopterus were integrated into Vanellus to align with shared anatomical features such as spurred wings and crests.[25]Evolution and phylogeny
The family Charadriidae, which includes lapwings, originated as part of the broader Charadriiformes order during the late Cretaceous, with molecular evidence indicating that at least 14 shorebird clades, including Charadriidae, predate the K/T boundary around 65 million years ago, and subsequent diversification occurred during the Eocene warming period.[26] Fossil records support early charadriiform-like birds from the early Eocene, such as specimens from the London Clay Formation in the UK, suggesting the family's radiation followed the post-Cretaceous shorebird expansion.[27] Within Charadriidae, the genus Vanellus (lapwings) diverged from other plovers during the Miocene.[26] Phylogenetically, Vanellus forms a monophyletic clade within Charadriidae, positioned as sister to a group of Australasian plover genera including Anarhynchus, Peltohyas, and Erythrogonys, based on multigene analyses; alternative mitogenomic studies place it sister to Pluvialis (golden plovers).[26][28] Molecular phylogenies using mitochondrial DNA (mtDNA) and nuclear genes, such as those from complete mitogenomes, reveal that diversification within Vanellus was influenced by shifts to open grassland habitats, promoting adaptations like enhanced aerial displays and ground-nesting behaviors that distinguish lapwings from other plovers.[29] These traits likely evolved after the initial shorebird radiation, enabling exploitation of expansive, vegetated terrains in the Old World. The fossil record of lapwing-like birds includes early Miocene charadriids from Europe, with definitive Vanellus species appearing by the late Pliocene, as exemplified by Vanellus liffyae from central Australia (3.6-2.6 million years ago), indicating a gradual morphological specialization.[30] Key evolutionary events include a major radiation of Vanellus across the Old World during the Pleistocene ice ages, coinciding with climatic fluctuations that expanded grassland habitats and led to the current diversity of 24 extant species.[31] Hybridization remains rare but is documented in sympatric populations, such as between Vanellus armatus (blacksmith lapwing) and Vanellus spinosus in Malawi, highlighting occasional gene flow despite strong species barriers.[32] Genetic diversity within Vanellus varies, with mitogenomic studies indicating that southern Asian lineages are older than northern ones, as evidenced in the grey-headed lapwing (Vanellus cinereus), where expansion northward from continental Asia resulted in reduced diversity in peripheral populations like those in Japan.[33]List of species
The genus Vanellus comprises 24 recognized species of lapwings, as per the IOC World Bird List (version 15.1, 2025).[34] These species are distributed across Africa, Asia, Australia, Europe, and the Americas, with identification often relying on variations in crest length, presence and color of facial wattles, leg coloration, and plumage patterns such as spotting or banding. Recent taxonomic changes include the elevation of the River Lapwing (V. duvaucelii) from subspecies status to full species based on genetic and morphological evidence. Subspecies are noted where relevant, and conservation status is indicated per IUCN Red List assessments by BirdLife International (2025).
