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 collectively called lapwings but also contain the ancient red-kneed dotterel. A lapwing can be thought of as a larger plover.
The traditional terms "plover", "lapwing" and "dotterel" were coined long before modern understandings of the relationships between different groups of birds emerged: in consequence, several of the Vanellinae are still often called "plovers", and the reverse also applies, albeit more rarely, to some Charadriinae (the "true" plovers and dotterels).
In Europe, "lapwing" often refers specifically to the northern lapwing, the only member of this group to occur in most of the continent.
While authorities generally agree that there about 25 species of Vanellinae, classifications within the subfamily remain confused. At one extreme, Peters recognised no less than 20 different genera for the birds listed in 2 genera here; other workers have gone so far as to group all the "true" lapwings (except the red-kneed dotterel) into the single genus Vanellus. Current consensus favors a more moderate position, but it is unclear which genera to split. The Handbook of Birds of the World provisionally lumps all Vanellinae into Vanellus except the Red-kneed Dotterel, which is in the monotypic Erythrogonys. Its plesiomorphic habitus resembles that of plovers, but details like the missing hallux (hind toe) are like those of lapwings: it is still not entirely clear whether it is better considered the basalmost plover or lapwing.
