Description
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 (4.5–12 oz). It has rounded wings and a crest. It is the shortest-legged of the lapwings. It is mainly black and white, but the back is tinted green. The male has a long crest and a black crown, throat and breast contrasting with an otherwise white face. Females and young birds have shorter crests, and have less strongly marked heads, but plumages are otherwise quite similar.
The name lapwing has been variously attributed to the "lapping" sound its wings make in flight, from the irregular progress in flight due to its large wings (OED derives this from an Old English word meaning "to totter"), or from its habit of drawing potential predators away from its nest by trailing a wing as if broken. This is a vocal bird in the breeding season, with constant calling as the crazed tumbling display flight is performed by the male. The typical contact call is a loud, shrill "pee-wit" from which they get their other name of Peewit. Displaying males usually make a wheezy "pee-wit, wit wit, eeze wit" during their display flight, these birds also make squeaking or mewing sounds.
It feeds primarily on insects and other small invertebrates. This species often feeds in mixed flocks with Golden Plovers and Black-headed Gulls, the latter often robbing the two plovers, but providing a degree of protection against predators.
Like the Golden Plovers, this species prefers to feed at night when there is moonlight.
The Northern Lapwing is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.

Famous quotes containing the word description:
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
“As they are not seen on their way down the streams, it is thought by fishermen that they never return, but waste away and die, clinging to rocks and stumps of trees for an indefinite period; a tragic feature in the scenery of the river bottoms worthy to be remembered with Shakespeare’s description of the sea-floor.”
—Henry David Thoreau (1817–1862)
“An intentional object is given by a word or a phrase which gives a description under which.”
—Gertrude Elizabeth Margaret Anscombe (b. 1919)
