Typical Antbirds (Thamnophilidae)

Collared Antshrike (Sakesphorus bernardi) - HBW 8, p. 541

French: Batara de Bernard German: Fleckengesicht-Ameisenwürger Spanish: Batará Collarejo
Other common names: White-naped Antshrike

Taxonomy: Tamnophilus [sic] Bernardi Lesson, 1844, Guayaquil, Guayas, Ecuador.
Probably forms a superspecies with S. canadensis and S. cristatus. Some plumage differences among Pacific slope populations are inconstant and others appear to be clinal; diagnostic differences of described races piurae and cajamarcae (SW Ecuador, NW Peru) not discernible, and those forms are therefore merged with nominate, pending further study. Two subspecies recognized.

Subspecies and Distribution:

  • bernardi (Lesson, 1844) - WC & SW Ecuador (Manabí, Guayas including Puna I, El Oro, Loja) and NW & NC Peru (Pacific slope in Tumbes and Piura S to N Ancash).
  • shumbae Carriker, 1934 - NC Peru (R Marañón drainage in Cajamarca and Amazonas).
