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. , Southern race, V. m. novaehollandiae in Queensland.

"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.

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.
