The bird family Charadriidae includes the plover
Plover
Plovers are a widely distributed group of wading birds belonging to the subfamily Charadriinae. There are about 40 species in the subfamily, most of them called "plover" or "dotterel". The closely related lapwing subfamily, Vanellinae, comprises another 20-odd species.Plovers are found throughout...

Lapwing
Vanellinae are any of various crested plovers, family Charadriidae, noted for its slow, irregular wingbeat in flight and a shrill, wailing cry. Its length is 10-16 inches. They are a subfamily of medium-sized wading birds which also includes the plovers and dotterels. The Vanellinae are...

In biology, a species is one of the basic units of biological classification and a taxonomic rank. A species is often defined as a group of organisms capable of interbreeding and producing fertile offspring. While in many cases this definition is adequate, more precise or differing measures are...

Bird
Birds are feathered, winged, bipedal, endothermic , egg-laying, vertebrate animals. Around 10,000 living species and 188 families makes them the most speciose class of tetrapod vertebrates. They inhabit ecosystems across the globe, from the Arctic to the Antarctic. Extant birds range in size from...

Distribution

Diet and feeding

They hunt by sight, rather than by feel as longer-billed waders like snipe
Snipe
A snipe is any of about 25 wading bird species in three genera in the family Scolopacidae. They are characterized by a very long, slender bill and crypsis plumage. The Gallinago snipes have a nearly worldwide distribution, the Lymnocryptes Jack Snipe is restricted to Asia and Europe and the...

 do. Foods eaten include aquatic and terrestrial invertebrates such as insects, worms, molluscs and crustaceans depending on habitat, and are usually obtained by a run-and-pause technique, rather than the steady probing of some other wader groups. They also feed on plant material.

Breeding

While breeding, they defend their territories with highly visible aerial displays.. Charadriidae are protective over their eggs and offspring. The parents protect their young by uttering an alarm call, performing distraction display
Distraction display
Distraction displays, also known as deflection display, diversionary display or paratrepsis, are anti-predator behaviours used to attract the attention of an enemy away from an object, typically the nest or young, that is being protected. They are particularly well known in birds but noted also in...

 and they may even attack the predator or intruder. Both parents take care of their offspring. The chicks are precocial; their parents do not feed them. Most species are monogamous, while less are polygamous.

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 Charadriinae.

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
