New World Warblers (Parulidae)

Flavescent Warbler (Basileuterus flaveolus) - HBW 15, p. 795

French: Paruline flavescente German: Gilbwaldsänger Spanish: Reinita Amarillenta

Taxonomy: Myiothlypis flaveolus S. F. Baird, 1865, "Paraguay" (probably = Paraguay River).
Often placed together with B. leucoblepharus, B. leucophrys, B. fulvicauda and B. rivularis in a separate genus, Phaeothlypis; differs from those four, however, in having no particular affinity for water and having quite different plumage. Formerly included within the "citrine" group of Andean species (B. luteoviridis, B. signatus and B. nigrocristatus), which it resembles in plumage. Appears to represent closest link between the Phaeothlypis group and the rest of present genus. Widely remote populations in NE Colombia and .. View all taxonomy...

Monotypic.
