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 {{cvt|2713|m}} 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.{{ cite journal | last1=Parker | first1=T.A. | last2=O'Neill | first2=J.P. | date=1985 | title=A new species and a new subspecies of Thryothorus wren from Peru | journal=Ornithological Monographs | volume=36 | pages=9-15 [12-15] | jstor=40168273 | doi=10.2307/40168273 }} It is now treated as a separate species based on
