Riverbank Warbler

About the Riverbank Warbler

The riverbank warbler (Myiothlypis rivularis) is a species of bird in the family Parulidae, the New World warblers. It is found in Argentina, Bolivia, Brazil, French Guiana, Guyana, Paraguay, and Uruguay. The riverbank warbler was formally described in 1821 with the binomial Muscicapa rivularis.

The riverbank warbler has a complicated taxonomic history since its original description. At some time in the nineteenth century it was reassigned to genus Basileuterus that had been erected in 1848. In 1929 W. E. Clyde Todd erected a new genus, Phaeothlypis, and in 1968 other authors assigned rivularis to it. In the early twenty-first century several studies confirmed that many species in Phaeothlypis were nested within Basileuterus but that the latter was polyphyletic. By 2007 taxonomic systems had begun to resurrect genus Myiothlypis, which had been erected in 1850, for the riverbank warbler and many other species. Some late twentieth century authors treated the riverbank warbler and the buff-rumped warbler (M. fulvicauda) as conspecific, and there is some evidence that they form a superspecies.

The riverbank warbler has also borne the English names "Neotropical... Wikipedia →
