Taxonomy and systematics
What is now the Peruvian wren was formerly called sepia-brown wren and at that time included as subspecies what are now the species Cinnycerthia olivascens and C. fulva.Kroodsma, D. E. and D. Brewer (2020). Peruvian Wren (Cinnycerthia peruana), version 1.0. In Birds of the World (J. del Hoyo, A. Elliott, J. Sargatal, D. A. Christie, and E. de Juana, Editors). Cornell Lab of Ornithology, Ithaca, NY, USA. https://doi.org/10.2173/bow.perwre1.01 retrieved June 2, 2021 Confusingly, after the split the name sepia-brown wren was transferred to C. olivascens by the International Ornithological Committee (IOC), but the South American Classification Committee of the American Ornithological Society (SACC/AOS) and the Clements taxonomy call it Sharpe's wren. C. fulva is named fulvous wren.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S. Claramunt, A. Jaramillo, D. F. Lane, J. F. Pacheco, M. B. Robbins, F. G. Stiles, and K. J. Zimmer.
