The masked lapwing (Vanellus miles), also known as the masked plover and often called the spur-winged plover or just plover in its native range, is a large, common and conspicuous bird native to Australia, particularly the northern and eastern parts of the continent, New Zealand and New Guinea. It spends most of its time on the ground searching for food such as insects and worms and has several distinctive calls. There are two subspecies; the southern novaehollandiae has distinctive black markings on the shoulder and side of the chest, and is sometimes recognized as a separate species, the black-shouldered lapwing (Vanellus novaehollandiae). These brown-black, white and yellow plovers are common in Australian fields and open land. Masked lapwings are shy and harmless in summer and autumn but are best known for their bold nesting habits, being quite prepared to make a nest on almost any stretch of open ground, including suburban parks and gardens, school ovals, and even supermarket carparks and flat rooftops. They can be particularly dangerous at airports where their reluctance to move from their nesting area – even for large aircraft – has resulted in several bird strikes. Breeding usually happens after winter solstice (June 21), but sometimes before. The nesting pair defends their territory against all intruders by calling loudly, spreading their wings, and then swooping fast and low, and where necessary striking at interlopers with their feet and attacking animals on the ground with a conspicuous yellow spur on the carpal joint of the wing.The bird may also use tactics such as fiercely protecting a non-existent nest, or a distraction display of hopping on a single leg, to attract a potential predator's attention to itself and away from its real nest or its chicks after they have commenced foraging. There seems to be some significant use of language to guide chicks during a perceived dangerous situation.
