New World Warblers (Parulidae)

Riverbank Warbler (Basileuterus rivularis) - HBW 15, p. 797

French: Paruline des rives German: Flusswaldsänger Spanish: Reinita Ribereña
Other common names: Neotropic/Neotropical/American River Warbler, Riverside Warbler

Taxonomy: Muscicapa rivularis Wied, 1821, Villa dos Ilhéos, Bahia, Brazil.
Often placed together with B. flaveolus, B. leucoblepharus, B. leucophrys and B. fulvicauda in a separate genus, Phaeothlypis. Forms a superspecies with B. fulvicauda; sometimes considered conspecific, but songs differ and it seems likely that the obvious buff rump and tail of the latter species would prevent interbreeding should the two ever come into contact. Three subspecies recognized.

Subspecies and Distribution:

  • mesoleucus P. L. Sclater, 1865 - E Venezuela, the Guianas and N Brazil.
  • bolivianus Sharpe, 1885 - E foothills of Andes in Bolivia.
  • rivularis ( Wied, 1821) - SE Brazil, E Paraguay and extreme NE Argentina.
