Ovenbirds (Furnariidae)

Plain-crowned Spinetail (Synallaxis gujanensis) - HBW 8, p. 285

French: Synallaxe de Cayenne German: Braunkappen-Dickichtschlüpfer Spanish: Pijuí Coronipardo
Other common names: Guianan Spinetail

Taxonomy: Motacilla gujanensis J. F. Gmelin, 1789, Guiana = “Cayenne”.
Forms a superspecies with S. maranonica and S. albilora, and all three are often treated as conspecific. S races, geographical variation in which is step-clinal, are vocally closer to latter species and become more like it in plumage as their ranges approach each other. Thorough analysis of species limits required. Further, boundaries of various races uncertain; inornata intergrades with certhiola in Beni Valley (Bolivia), and birds from lower R Purús E to lower R Madeira (Brazil) are evidently intermediate between former and nominate; rigorous analysis may reveal..

Taxonomy: Motacilla gujanensis J. F. Gmelin, 1789, Guiana = “Cayenne”.
Forms a superspecies with S. maranonica and S. albilora, and all three are often treated as conspecific. S races, geographical variation in which is step-clinal, are vocally closer to latter species and become more like it in plumage as their ranges approach each other. Thorough analysis of species limits required. Further, boundaries of various races uncertain; inornata intergrades with certhiola in Beni Valley (Bolivia), and birds from lower R Purús E to lower R Madeira (Brazil) are evidently intermediate between former and nominate; rigorous analysis may reveal widespread clinal variation that would render division into races impossible. Six subspecies recognized.

Subspecies and Distribution:

  • columbiana Chapman, 1914 - E Colombia (W Meta S to Putumayo).
  • gujanensis (J. F. Gmelin, 1789) - E & S Venezuela (E Monagas S to Bolívar and N Amazonas), the Guianas and N & E Brazil (Amazonas and N Roraima E to Amapá and, S of R Amazon, from Pará and N Mato Grosso E to Maranhão and N Goiás).
