published in 1820. Most members of the family are known as ''plovers'', ''lapwings'' or ''dotterels''. These were rather vague terms which were not applied with any great consistency in the past. In general, larger species have often been called ''lapwings'', smaller species ''plovers'' or ''dotterels'' and there are in fact two clear taxonomic sub-groups: most lapwings belong to the subfamily
Vanellinae, most plovers and dotterels to

While breeding, they defend their territories with highly visible aerial displays.
Charadridae lay two to four eggs into the nest, which is usually a shallow scrape in the open ground, and incubate the clutch for 21–30 days.
In species where both parents incubate the eggs, females and males vary in the way they share their incubation duties, both within and between species. In some pairs, parents exchange on the nest in the morning and in the evening so that their incubation rhythm follows 24-hour day, in others females and males exchange up to 20 times a day.
