About the Black-winged Lapwing
The Black-winged Lapwing, scientifically known as Vanellus melanopterus, is an intriguing bird species belonging to the Charadriidae family. This medium-sized wader is primarily found across the eastern and southern regions of Africa. Its presence is notable in countries such as Kenya, Tanzania, Zambia, Zimbabwe, and South Africa. The bird's habitat preferences include open grasslands and high-altitude moorlands, where its striking black wings and contrasting white face make it an unmistakable figure. The Black-winged Lapwing plays a vital ecological role in its environment, particularly in its interaction with the invertebrate fauna of its habitat. It preys on a variety of insects and other small invertebrates, helping to control their populations and maintain ecological balance in grassland ecosystems. During the breeding season, this species' behavior becomes particularly fascinating as they engage in elaborate courtship displays. These displays involve a combination of vocalizations and physical movements designed to attract mates and establish territories. The Black-winged Lapwing is a partial migrant, meaning that some populations may move in response to seasonal changes in resource availability. In the cooler months, they may descend to lower elevations or move to areas where food is more plentiful. This adaptability is one of the reasons why they thrive in a range of environments. Conservation-wise, the Black-winged Lapwing is not currently considered to be at risk. However, habitat loss due to agricultural expansion poses potential threats. Therefore, maintaining the integrity of their natural habitats is crucial for their continued survival. Their preference for high-altitude grasslands means they are also sensitive to changes in climate and land use, making them an important species for monitoring environmental health in these regions.
The Black-winged Lapwing belongs to the family Charadriidae, within the order Charadriiformes. These birds typically live average 5-7 years with a maximum recorded of 9 years..
How to Identify a Black-winged Lapwing
The Black-winged Lapwing is easily recognized by its contrasting plumage. Adults display a predominantly grey body with a white face and throat, bordered by a distinct black line running from the base of the beak over the eye to the nape. The wings, as the name suggests, are primarily black, offering a striking contrast against the bird's lighter body. In flight, the white underwing coverts and the white trailing edge of the wings become evident, creating a memorable silhouette. Juveniles resemble adults but tend to have a less clear delineation between the face and throat colors, and their plumage may appear mottled. Despite these differences, juveniles still possess the characteristic black wings. Males and females exhibit similar plumage, making gender differentiation challenging without behavioral cues. However, during the breeding season, males may display more vibrant facial markings. The Black-winged Lapwing could be confused with the Crowned Lapwing, which also inhabits similar environments. However, the latter has a distinct black cap bordered with a white halo, and its wing pattern in flight is less contrasting. Observing the bird's posture can also aid identification, as the Black-winged Lapwing often adopts an upright stance, especially when alarmed or displaying.

Black-winged Lapwing Habitat and Range
Preferred Habitat
The Black-winged Lapwing primarily inhabits open grasslands and high-altitude moorlands, favoring regions between 1,500 and 3,000 meters above sea level. In Kenya and Tanzania, these birds are commonly found in the grasslands of the Rift Valley and highland areas such as the Aberdare Mountains and the Laikipia Plateau. During non-breeding seasons, they may also occupy cultivated lands and pastures, demonstrating their adaptability to modified landscapes. Although they are predominantly found in rural areas, occasional sightings in peri-urban environments suggest some level of tolerance to human presence. Seasonal movements may occur in response to rainfall patterns, with the birds relocating to areas where food resources are more abundant.
Geographic Range
The Black-winged Lapwing's range covers a significant portion of sub-Saharan Africa. It breeds primarily in the highland regions of Kenya, Tanzania, and Ethiopia, where the climate and habitat conditions are optimal. Further south, populations are found in Zimbabwe, Zambia, and the highveld regions of South Africa. While the species is not considered a long-distance migrant, certain populations exhibit local movements in response to seasonal changes. For instance, during the dry season, some birds may move from higher to lower altitudes in search of food and water. These movements can lead them into regions such as the Limpopo and North West Provinces in South Africa. Populations are generally denser in regions with extensive grasslands and minimal human disturbance, although they have shown adaptability to certain agricultural areas.

What Does the Black-winged Lapwing Eat?
Feeding primarily on invertebrates, the Black-winged Lapwing's diet consists of beetles, grasshoppers, termites, and other small insects. During the wetter months, when these prey items are more abundant, the lapwing can be seen actively foraging across grasslands and moorland habitats. It employs a technique known as 'run-and-pause' foraging, where the bird runs a short distance, pauses to scan for prey, and then captures its target with precision. This method is particularly effective in open areas where insects are active. The lapwing's foraging activity is typically diurnal, with peak feeding periods occurring during the early morning and late afternoon when temperatures are cooler and insect activity is heightened. In addition to insects, the lapwing may also consume small seeds and plant matter, particularly during times when its primary food sources are less available.
Black-winged Lapwing Behavior and Social Structure
The Black-winged Lapwing displays a complex social structure, often forming small flocks outside the breeding season. These flocks can consist of a few individuals to several dozen, depending on resource availability. During breeding, the lapwing becomes more territorial, with males establishing and defending nesting sites through vocalizations and physical displays. One of the most notable behaviors is the bird's courtship display, which involves a series of calls and aerial maneuvers designed to attract a mate and deter rivals. This display is often accompanied by ritualized movements such as wing flapping and bowing, which serve to strengthen pair bonds. The lapwing is generally active during the day, with its activity peaking in the early morning and late afternoon. When threatened by predators, it employs a variety of strategies, including distraction displays and alarm calls, to protect nests and young. These behaviors underscore the bird's adaptability and intelligence in responding to environmental challenges.
Black-winged Lapwing Nesting and Reproduction
The Black-winged Lapwing typically nests on the ground in open areas, creating a simple scrape in the soil lined with grass and small stones. Preferred nesting sites include high-altitude grasslands and moorlands, where the bird can take advantage of the sparse vegetation for concealment. Clutch size usually ranges from two to four eggs, which are well-camouflaged against the ground. Both parents participate in incubation, which lasts approximately 26 to 30 days. After hatching, the chicks are precocial, leaving the nest within hours and following the parents to nearby feeding areas. The parents maintain a close watch over the young, providing protection and guidance as they learn to forage for themselves. Fledging occurs around 30 to 35 days after hatching, but the juveniles may remain with the parents for a few more weeks as they develop their independence. The Black-winged Lapwing typically raises one brood per year, although favorable conditions may occasionally lead to a second.
Black-winged Lapwing Sounds and Vocalizations
The primary vocalization of the Black-winged Lapwing is a distinctive 'kree' or 'kree-kree' sound, delivered in quick succession. This call serves various purposes, including territory defense and mate attraction. During the breeding season, their vocalizations become more frequent, with males often calling from elevated perches or in flight to establish dominance and advertise their presence. Alarm calls are sharper and more urgent, intended to warn other birds of potential threats. These calls may be accompanied by distraction displays if a predator approaches a nesting site. The lapwing's dawn chorus, particularly in high-density areas, can be a lively affair, with numerous individuals calling simultaneously to reinforce social bonds and territorial boundaries.
