Taxonomy

The tawny-crowned greenlet was formally described in 1860 by the English zoologist Philip Sclater. The specimen had been collected in the state of Oaxaca of southwest Mexico by the French ornithologist Adolphe Boucard. Sclater coined the binomial name Hylophilus ochraceiceps. ^[2] The specific name combines the Modern Latin ochraceus meaning "ochraceous" with -ceps meaning "-capped". ^[3] The species is now placed in the monotypic genus Tunchiornis that was introduced in 2014. ^{[4] [5]}

Ten subspecies are recognised: ^[5]

• T. o. pallidipectus (Ridgway, 1903) – south Guatemala and Honduras to northwest Panama
• T. o. pacificus (Parkes, 1991) – southeast Costa Rica and west Panama
• T. o. nelsoni (Todd, 1929) – east Panama

• T. o. ferrugineifrons (Sclater, PL, 1862) – southeast Colombia, south Venezuela, west-central Guyana, northwest Brazil, Ecuador and Peru
• T. o. viridior (Todd, 1929) – south Peru and north Bolivia
• T. o. luteifrons (Sclater, PL, 1881) – east Venezuela, the Guianas and north Brazil
• T. o. lutescens (Snethlage, E, 1914) – north-central Brazil south of the Amazon
