Ringed Plover — Charadrius hiaticula and Semipalmated Plover — Charadrius semipalmatus

Abstract

Since Ringed Plover and Semipalmated Plover have a close phenotypical resemblance, the analysis of both is combined in a single chapter. The Ringed Plover has a primarily Palearctic breeding distribution under temperate, boreal, and arctic conditions, and the Semipalmated Plover is its Nearctic counterpart, breeding under more or less the same conditions (figs. 15 & 16). The Semipalmated Plover breeds more inland and not as far to the north as the Ringed Plover. The breeding range in Russia and Siberia might not be as continuous as shown on the published maps with the breeding ranges of Ringed Plovers. There are important gaps in our knowledge, concerning the nesting of this species on:

• the Kola Peninsula,

• around and south of the Bolshezemelsk tundra,

• between the Anabar and Lena river,

• along the north coast east of the Lena River as far east as the Indigirka,

• along the north coast of the Chukotsk Peninsula,

• the flood plains of the Kolyma River,

• the southernmost extent of the breedingarea in E Siberia.
