In flight with wing spurs clearly visible. The masked lapwing is the largest representative of the family Charadriidae.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.
The traditional terms "plover", "lapwing", and "dotterel" do not correspond exactly to current taxonomic models; thus, several of the Vanellinae are often called plovers, and one a dotterel, while a few of the "true" plovers (subfamily Charadriinae) are known colloquially as lapwings. In general, a lapwing can be thought of as a larger plover.
In most genera, the sexes are similar, very little sexual dimorphism occurs between sexes. They range in size from the collared plover, at 26 grams and 14 cm (5.5 in), to the masked lapwing, at 368 grams (0.811 pounds) and 35 cm (14 in).
This lapwing is the only crested wader in South America. It is 32 to 38 cm (13 to 15 in) in length and weighs approximately 250 to 425 g (8.8 to 15.0 oz). The upperparts are mainly brownish grey, with a bronze glossing on the shoulders.
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.
Linnaeus based his account on a description by the Swedish naturalist Fredrik Hasselquist that had been published in 1757. [5] The spur-winged lapwing is now one of 23 species placed in the genus Vanellus that was introduced in 1760 by the French naturalist Mathurin Jacques Brisson. The species is monotypic: no subspecies are recognised. [6]

The northern lapwing is a 28–33 cm (11–13 in) long bird with a 67–87 cm (26–34 in) wingspan and a body mass of 128–330 g (4.5–11.6 oz). [10] It has rounded wings and a crest. It is also the shortest-legged of the lapwings. It is mainly black and white, but the back is tinted green.
