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.{{ cite journal | last=Sclater | first=Philip Lutley| author-link=Philip Sclater | year=1860| title=List of birds collected by M. A.
