New World Warblers (Parulidae)

Buff-rumped Warbler (Basileuterus fulvicauda) - HBW 15, p. 796

French: Paruline à croupion fauve German: Schmätzerwaldsänger Spanish: Reinita Culiparda

Taxonomy: Muscicapa fulvicauda Spix, 1825, no locality = São Paulo de Olivença, River Solimões, Brazil.
Often placed together with B. flaveolus, B. leucoblepharus, B. leucophrys and B. rivularis in a separate genus, Phaeothlypis. Forms a superspecies with B. rivularis; sometimes considered conspecific, but songs differ and it seems likely that obvious buff rump and tail of present species (which is continuously signalled) would prevent interbreeding should the two ever come into contact. Six subspecies recognized.

leucopygius P. L. Sclater & Salvin, 1873 - NC Honduras S to Caribbean slope of W Panama.
veraguensis Sharpe, 1885 - Pacific slope from SW Costa Rica S to C Panama.
