Overview
The Masked Lapwing, colloquially called the Spur-winged Plover, is a unique bird species recognized by its distinctive features and expressive behavior. This bird is native to Australia and New Zealand, where it is highly noticeable due to its large yellow wattles, a spur on each wing, and characteristic alarm calls. The species is known for its assertive and almost intrepid demeanor, appearing undeterred by human presence or larger animals. A substantial part of their reputation stems from loud calls, which alert and intimidate potential threats in their territory.
Primarily terrestrial birds, Masked Lapwings are often sighted in open habitats. They prefer wetlands and farmlands, where their foraging lifestyle thrives. Adapted to human proximity, they are common in urban parks, sports fields, and other open areas within city boundaries. This adaptability contributes to their widespread distribution and relative abundance, a testament to their resilience in various environmental conditions.
Perhaps the most noteworthy aspect of the Masked Lapwing’s behavior is exhibited during the breeding season. During this period, they display high aggression and territoriality to protect their nests and offspring. Their bold behavior escalates to such an extent that they are known to swoop and dive at perceived intruders, which has earned them a certain level of notoriety. Despite this aggression, their aim is usually non-contact intimidation to ward off potential threats rather than cause physical harm. These intriguing behaviors make the Masked Lapwing a fascinating subject of study and observation.

Physical Description:
The Masked Lapwing is a large and robust bird featuring predominantly white underparts and dark grey to black upperparts. Their most noticeable feature is the large yellow wattles covering the face, hence the name “Masked” Lapwing. The bill is yellow, and the legs and eye-rings are a bright yellow-orange. During the flight, a prominent white wing stripe becomes visible.
Two distinct races of the species exist the Southern Lapwing (V. m. novaehollandiae), which also has a black hind-neck and smaller wattles, and the Northern Lapwing (V. m. miles), which has a white hind-neck and larger wattles. Additionally, this bird possesses a sharp spur on its wings, a feature giving rise to its alternative name, the Spur-winged Plover. Males and females are similar in appearance, although males may have larger spurs and wattles.

Native Habitat:
The native habitat of the Masked Lapwing is quite diverse and includes both natural and human-modified environments. They prefer open areas and can be found in wetlands, grasslands, and farmlands. Furthermore, they have adapted quite well to human environments and can be seen in urban parks, sports fields, and even school playgrounds.
Masked Lapwings are known for their resilience and adaptability, able to inhabit regions from coastal shorelines to semi-arid inland areas. They are often associated with water, a crucial requirement for feeding and breeding. The species can be found from sea level up to altitudes of approximately 4000 meters.

Diet & Feeding Habits:
Masked Lapwings are omnivorous birds, feeding on various food items. Their diet mainly consists of insects, worms, and other small invertebrates that they forage for on the ground. They also eat seeds, grains, and occasionally small fish or amphibians when available.
Masked Lapwings can also catch insects in flight despite their preference for foraging on the ground. They are also opportunistic feeders, often scavenging in urban environments and capitalizing on human-provided food sources. Their foraging behavior is mainly solitary or in pairs, though non-breeding birds may sometimes form loose flocks.
Mating Behavior:
Mating Description:
Masked Lapwings are monogamous birds, forming long-term pair bonds. Their breeding season is quite flexible and can occur at any time of the year, typically in spring and early summer. During courtship, males display a series of calls and visual signals to females.
The female lays three to four brown-speckled eggs in a ground nest, which both parents defend vigorously. The Masked Lapwing is particularly well-known for its aggressive protection of the nest and young. Both parents share the incubation duty, which lasts for about 28 days.

Social Structure Description:
Masked Lapwings are social birds, but their group dynamics can vary. Outside the breeding season, they can form large flocks, often seen foraging together in open areas. During the breeding season, they become territorial and often be seen in pairs or as lone individuals.
They are highly defensive of their nesting area and often behave aggressively to ward off potential threats, including humans. A complex set of vocalizations and visual signals characterizes their social interactions.

Population Trend:
The Masked Lapwing population is generally stable and robust across its range, owing to its ability to thrive in various environments, including human-modified landscapes. However, like any species, localized declines can occur due to habitat loss or disturbance.
In some areas, Masked Lapwings are regarded as pests due to their aggressive behavior during the nesting season, occasionally leading to conflict with humans. On the other hand, their presence in urban areas often provides opportunities for education and appreciation of wildlife.
Population Threats:
Despite their stable status, Masked Lapwings do face specific threats. One significant issue is habitat loss, especially in wetland areas, due to urban development and agriculture expansion. Furthermore, the use of pesticides can affect their food sources.
They are also at risk from human-related activities such as vehicular collisions and unintentional disturbance of nests in urban and suburban areas. Their defensive behavior during nesting can lead to negative interactions with humans, sometimes resulting in the removal or destruction of nests.
Conservation Efforts:
Given their Least Concern status, no specific conservation measures are targeted at Masked Lapwings. However, their habitats are often protected under broader environmental regulations and policies to preserve biodiversity.
Public education is also essential to their conservation, especially in urban areas where their aggressive nesting behavior can lead to conflict. Raising awareness about the importance of these birds and how to avoid disturbing their nests is crucial in fostering coexistence.
