Woodcreepers (Dendrocolaptidae)
Olive-backed Woodcreeper (Xiphorhynchus triangularis) - HBW 8, p. 434
French: Grimpar à dos olive
German: Olivrücken-Baumsteiger
Spanish: Trepatroncos Dorsioliva
Taxonomy: Dendrocolaptes triangularis Lafresnaye, 1842, Bolivia; error = “Santa Fe de Bogotá”, Colombia.
Sister-species to X. erythropygius. The two sometimes regarded as forming a superspecies, or as conspecific; treatment as separate species supported by molecular evidence, vocalizations, apparent lack of intergradation, and elevational replacement where ranges approach (at most, very limited sympatry on W slope of Andes in SW Colombia and W Ecuador). Described race distinctus (from W Andes of Colombia) synonymized with nominate; hylodromus differs only slightly from nominate, but is geographically disjunct; intermedius intergrades with and possibly indistinguishabl..

Sister-species to X. erythropygius. The two sometimes regarded as forming a superspecies, or as conspecific; treatment as separate species supported by molecular evidence, vocalizations, apparent lack of intergradation, and elevational replacement where ranges approach (at most, very limited sympatry on W slope of Andes in SW Colombia and W Ecuador). Described race distinctus (from W Andes of Colombia) synonymized with nominate; hylodromus differs only slightly from nominate, but is geographically disjunct; intermedius intergrades with and possibly indistinguishable from bangsi. Four subspecies recognized.
Subspecies and Distribution:
- hylodromus Wetmore, 1939 - coastal and interior mountains of N Venezuela (Andes in Trujillo and SE Lara, Yaracuy E to Miranda and Distrito Federal).
- triangularis (Lafresnaye, 1842) - Andes of W Venezuela (Zulia, SW Táchira, Mérida), Colombia (W, C & E cordilleras except in W Nariño), E Ecuador and N Peru (N of R Marañón).
- intermedius Carriker, 1935 - Andes of C Peru (Pasco, Junín).
- bangsi Chapman, 1919 - E Andean slopes from SE Peru S to C Bolivia (La Paz, Cochabamba, W Santa Cruz), intergrades with intermedius in SE Peru.
