There is a much-believed but incorrect myth that the spur can inject venom. Breeding usually happens after winter solstice(June 21), bu… "They usually give off a high-pitched warning call, to let you know they are there, sitting on their nest," Ms Kostoglou said. Hoplopterus miles (Boddaert, 1783) Follow ABC Emergency for the latest information on 45 bush and grass fires burning across NSW, Follow our live coverage for the latest news on the coronavirus pandemic. 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. But painting the masked lapwing as an evil swoopy bird is somewhat misleading. The birds have a wide range of calls which can be heard at any time of the day or night: the warning call, a loud defending call, courtship calls, calls to its young, and others. It is a diminutive of the Latin vanus meaning "winnowing" or "fan". Then, she puts the egg in a soundproof box with a high-powered microphone and records the calls coming from the chick inside. [11][12], The masked lapwing is the largest representative of the family Charadriidae. "It's just a warning to let you know you're in their area — they won't usually make contact.". The masked lapwing has small spurs on its elbow-y bits, turning it into a feathered, flying, jousting monster. "About a day after hatching the egg tooth just falls off, and they begin to feed like normal," Ms Kostoglou said.

It is common in Australian fields and open land, and is known for its defensive swooping behaviour during the nesting season. "The parents will hear the calls and can alter what they're doing [on the nest] to restore the embryo back to its optimal temperature. Attacks are most vicious on other birds such as ravens, and also on cats and dogs, but once the chicks reach 60% of full size after 2–3 months, the chances of this happening decrease. Masked lapwings are protective of their young in the breeding season, divebombing any threat to their ground reared chicks. [13], Southern race, V. m. novaehollandiae in Queensland. So the story of the terrifying masked lapwing is not so cut and dry. Get all the latest science stories from across the ABC. "Then, if you get too close, they might hop off the nest and some will swoop you. Although plovers are technically shorebirds — and the masked lapwing can be found in coastal habitats — this plover has also carved out an urban niche for itself, on grassy lawns throughout northern, central and eastern Australia. It measures from 30 to 37 cm (12 to 15 in) in length and has a wingspan of 75–85 cm (30–33 in), and has a conspicuous yellow spur on the carpal joint of each wing. But if you are really unlucky, and continue to get too close to their nest, they might bring out the spurs, Ms Kostoglou said. "There is one display where they will puff out their chest and open up their wings as big as they can, and then slowly walk towards you," Ms Kostoglou said.

The masked lapwing was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in his Histoire Naturelle des Oiseaux in 1781. The chick reaches full growth after 4 to 5 months and will often stay with the parents for 1 to 2 years resulting in family groups of 3 to 5 birds nesting in one location over the summer. "If they feel like they are being threatened, or if they feel they need to be aggressive, you will be able to see the spurs pop out — and they can nick you with that," she said. The myth may have been based on fear of the masked lapwing's territorial behaviour. It screams at its enemies (humans, dogs, cats, bicycles, lawnmowers). But if you're most vulnerable when you're in your egg or just hatched, why would you draw attention to yourself by calling from within your egg? "And after a while of being warmed by their parents, the chicks' feathers become that downy beautiful fluff-ball.". The locality was re-designated by the Australian ornithologist Gregory Mathews in 1912 as Timor Laut (the Tanimbar Islands). Little is known about why and how bird chicks make calls from within their eggs, but Ms Kostoglou is trying to narrow it down for the masked lapwing. Sometimes the bird can damage its wing in a strike but usually survives and is flightless as the wing heals. The specific epithet miles is the Latin word for "soldier". To be precise, she's eavesdropping on the eggs — listening in to the noises coming from the chicks within the egg itself. 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. The plover parents really just want you to move along from their nesting area.
