Para Greenlet

The Para greenlet (Tunchiornis rubrifrons) is a passerine bird in the family Vireonidae, the vireos. It is found in South America, where it is endemic to the rainforests of Pará in Brazil. It was split from the ochre-crowned greenlet in 2025 by AviList and the Clements Checklist. Owing to its recent separation as a species, virtually nothing distinctive is known about its natural history.

Taxonomy: The Para greenlet was formally described in 1867 as Hylophilus rubrifrons by the English ornithologists Philip Sclater and Osbert Salvin but was soon after considered to be a subspecies of tawny-crowned greenlet (now called ochre-crowned greenlet).

Two subspecies are recognised:

• T. r. lutescens (Snethlage, E, 1914) – northern Brazil south of the Amazon River (Rio Madeira to Rio Xingú)
• T. r. rubrifrons (Sclater, PL & Salvin, O, 1867) – northeastern Brazil (Rio Tocantins to Pará)
