A general term for birds in the family Haematopodidae of the order Charadriiformes, or refers to one of those species. Birds in this family are distributed worldwide, except in the polar regions and the islands of Polynesia, and are classified into one genus and six species (some scholars classify them as four or seven species). One species, the Haematopod, occasionally migrates to Japan. Its total length is 40-52 cm. It has a fat body and comes in two types: one with white and black coloring and one that is completely black. There are theories that say that one species contains both types, and theories that say that the two are separate species, and the number of species varies depending on which one is considered.
