The collared plover (Charadrius collaris) is a small shorebird in the plover family, Charadriidae. It lives along coasts and riverbanks of the tropical to temperate Americas, from central Mexico south to Chile and Argentina. The female collared plover is usually very similar to the male, but some individuals can be sexed by a brown tinge to the black areas. Immature birds lack any black on the head, and the breast band is replaced by brown patches on each side of the chest. The flight call is a sharp metallic pip.
