There is a widely-believed myth that the spur can inject venom. That may have been based on fear of the masked lapwing's territorial behaviour. 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 two or three months, the chances of that happening decrease.

The masked lapwing (also known as the spur-winged plover) has carpal spurs. Nesting pairs defend 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 the conspicuous yellow spurs.
The trend in recent years has been to rationalise the common names of the Charadriidae. For example, the large and very common Australian bird traditionally known as the ‘spur-winged plover’, is now the masked lapwing; the former ‘sociable plover’ is now the sociable lapwing.

The food of the spur-winged lapwing is insects and other invertebrates, which are picked from the ground. It lays four blotchy yellowish eggs on a ground scrape. The spur-winged lapwing is known to sometimes use the wing-claws in an attack on animals and, rarely, people, who get too close to the birds' exposed offspring.
The nictitating membrane of a masked lapwing as it closes over the left eye, originating from the medial canthus. The nictitating membrane (from Latin nictare, to blink) is a transparent or translucent third eyelid present in some animals that can be drawn across the eye from the medial canthus to protect and moisten it while maintaining vision.
The yellow-wattled lapwing (Vanellus malabaricus) is a lapwing that is endemic to the Indian Subcontinent. It is found mainly on the dry plains of peninsular India and has a sharp call and is capable of fast flight. Although they do not migrate, they are known to make seasonal movements in response to rains.
Although the most familiar Eurasian lapwing, Vanellus vanellus (northern lapwing), has a wispy crest, only two other species do so. Red or yellow facial wattles are a more typical decoration. Only northern, sociable, white-tailed, grey-headed and brown-chested lapwings are truly migratory species.
