Subspecies
Often placed together with Flavescent Warbler (Myiothlypis flaveola), White-rimmed Warbler (Myiothlypis leucoblephara), White-striped Warbler (Myiothlypis leucophrys) and Southern Riverbank Warbler (Myiothlypis rivularis) in a separate genus, Phaeothlypis. Forms a superspecies with Southern Riverbank Warbler (Myiothlypis rivularis) and 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.
The following 7 subspecies are recognised:
leucopygius (Spix, 1825) - North-central Honduras south to Caribbean slope of western Panama.
veraguensis (Sharpe, 1885) - Pacific slope from south-western Costa Rica south to central Panama.
semicervina P. L. Sclater, 1860 - Eastern Panama and adjacent western Colombia southern in western Andes foothills to north-western Peru.
