Woodcreepers (Dendrocolaptidae)

Spotted Woodcreeper (Xiphorhynchus erythropygius) - HBW 8, p. 434

French: Grimpar tacheté German: Olivkappen-Baumsteiger Spanish: Trepatroncos Manchado
Other common names: Berlepsch’s/Ecuadorian/Spot-throated Woodcreeper (“aequatorialis group”)

Taxonomy: Dendrornis erythropygia P. L. Sclater, 1860, Veracruz and Oaxaca = Jalapa, Veracruz, Mexico.
Suggested sister-species to X. triangularis based on genetic comparison using “aequatorialis group”. 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 (with at most, very limited sympatry on W slope of Andes in SW Colombia and W Ecuador). On basis of plumage and, to a lesser degree, voice and elevational preference, races divided into “erythropygius group” (including parvus) a.. View all taxonomy...

Taxonomy: Dendrornis erythropygia P. L. Sclater, 1860, Veracruz and Oaxaca = Jalapa, Veracruz, Mexico.
Suggested sister-species to X. triangularis based on genetic comparison using “aequatorialis group”. 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 (with at most, very limited sympatry on W slope of Andes in SW Colombia and W Ecuador). On basis of plumage and, to a lesser degree, voice and elevational preference, races divided into “erythropygius group” (including parvus) and “aequatorialis group” (including punctigula and insolitus); races within each group poorly differentiated. Five subspecies recognized.

Subspecies and Distribution:

  • erythropygius (P. L. Sclater, 1860) - highlands of C & S Mexico (extreme SE San Luis Potosí and Hidalgo S to C Oaxaca, also Guerrero).
  • parvus Griscom, 1937 - S Mexican Highlands (extreme SE Oaxaca, Chiapas) and extreme NW El Salvador S to NC Nicaragua; also locally in S Belize.
  • punctigula (Ridgway, 1889) - SE Nicaragua S to C Panama (E to Veraguas).
