Woodcreepers (Dendrocolaptidae)

Streak-headed Woodcreeper (Lepidocolaptes souleyetii) - HBW 8, p. 442

French: Grimpar de Souleyet German: Lanzettstrichel-Baumsteiger Spanish: Trepatroncos Cabecirrayado
Other common names: Souleyet’s Woodcreeper

Taxonomy: Dendrocolaptes Souleyetii Des Murs, 1849, Paita, Piura, north-west Peru.
Appears to be closely related to L. affinis, L. lacrymiger and L. albolineatus. Races lineaticeps, littoralis and uaireni poorly differentiated from one another, whereas nominate and esmeraldae appear to represent extremes in a cline. Assessment of geographical variation complicated by marked individual and age-related variation in size, in width and extent of streaking above and below, in shade of upperparts, and in intensity of buff coloration on throat and underparts. Birds from SE Mexico to N Honduras often recognized as race insi.. View all taxonomy...

Taxonomy: Dendrocolaptes Souleyetii Des Murs, 1849, Paita, Piura, north-west Peru.
Appears to be closely related to L. affinis, L. lacrymiger and L. albolineatus. Races lineaticeps, littoralis and uaireni poorly differentiated from one another, whereas nominate and esmeraldae appear to represent extremes in a cline. Assessment of geographical variation complicated by marked individual and age-related variation in size, in width and extent of streaking above and below, in shade of upperparts, and in intensity of buff coloration on throat and underparts. Birds from SE Mexico to N Honduras often recognized as race insiginis, said to differ from compressus in deeper buff throat and broader streaking both above and below, but neither character seems geographically related and considered better merged with latter; variation in Middle America most evident as cline of decreasing size from N to S. Seven subspecies recognized.

Subspecies and Distribution:

  • guerrerensis van Rossem, 1939 - W Mexico (Sierra Madre del Sur, in Guerrero and SW Oaxaca).
  • compressus (Cabanis, 1861) - lowlands on both slopes of Middle America from S Mexico (S Veracruz, SW Campeche, SW Chiapas) S to W Panama (E Chiriquí, W Bocas del Toro).
  • lineaticeps (Lafresnaye, 1850) - C & E Panama (E from Canal Zone), N & E Colombia (except Santa Marta region) and W Venezuela (Táchira, W Mérida, extreme W Barinas).
