The grey-browed wren (Pheugopedius schulenbergi) is a small passerine bird in the wren family Troglodytidae. It is found in northern Peru north of the Río Marañón. It was formerly considered to be a subspecies of the plain-tailed wren.
Taxonomy The grey-browed wren was formally described in 1985 by the American ornithologists Theodore A. Parker III and John P. O'Neill based on a specimen that had been collected at an altitude of in the Cordillera de Colán of the Amazonas region of northern Peru. They considered the specimen to be a subspecies of the plain-tailed wren and coined the trinomial name Thryothorus euophrys schulenbergi where the specific epithet was chosen to honour Thomas S. Schulenberg who had collected the holotype. It is now treated as a separate species based on the distinctive vocalizations and some morphological differences.
