Charadrius

 Charadrius  is a genus of plovers, a group of wading birds. They are found throughout the world. Many of the Charadrius species are characterised by breast bands or collars. These can be (in the adult) complete bands (Ringed, Semipalmated, Little Ringed, Long-billed), double or triple bands (Killdeer, Three-banded, Forbes', Two-banded, Double-banded) or partial collars (Kentish, Piping, Malaysian, Javan, Red-capped, Puna).

They have relatively short bills and feed mainly on insects, worms or other invertebrates, depending on habitat, which are obtained by a run-and-pause technique, rather than the steady probing of some other wader groups. They hunt by sight, rather than by feel as do longer-billed waders like snipe.

Species of the genus Aegialites (or Aegialitis) are now subsumed within Charadrius.
