Typical Antbirds (Thamnophilidae)

Warbling Antbird (Hypocnemis cantator) - HBW 8, p. 645

French: Alapi carillonneur German: Rostflanken-Ameisenschnäpper Spanish: Hormiguero Cantarín

Taxonomy: Formicarius Cantatar [sic] Boddaert, 1783, Cayenne, French Guiana.
Although genus traditionally placed after Myrmoborus, it appears closely related to Drymophila. Present species regarded as sister-species of H. hypoxantha; recent genetic study, however, indicates considerable genetic distance between the two, suggesting that speciation occurred perhaps several million years ago. Present species as herein constituted almost certainly consists of more than one species, as races peruviana and collinsi known to occur together in same habitat, and some types of vocalizations vary substantially among races; taxonomic study curre..

Taxonomy: Formicarius Cantatar [sic] Boddaert, 1783, Cayenne, French Guiana.
Although genus traditionally placed after Myrmoborus, it appears closely related to Drymophila. Present species regarded as sister-species of H. hypoxantha; recent genetic study, however, indicates considerable genetic distance between the two, suggesting that speciation occurred perhaps several million years ago. Present species as herein constituted almost certainly consists of more than one species, as races peruviana and collinsi known to occur together in same habitat, and some types of vocalizations vary substantially among races; taxonomic study currently being undertaken. Birds from N of range (SE Venezuela, Guyana, N Brazil) described as race notaea, but considered indistinguishable by plumage or vocalizations from nominate. Ten subspecies recognized.

Subspecies and Distribution:

  • cantator (Boddaert, 1783) - extreme EC Venezuela (NE Bolívar), the Guianas and NE Amazonian Brazil (lower R Negro E to Amapá).
  • flavescens P. L. Sclater, 1865 - S Venezuela (W & S Bolívar, Amazonas), extreme NW Amazonian Brazil (upper R Negro drainage and N Roraima) and EC Colombia (Guainía, Vaupés, N Caquetá).
  • saturata Carriker, 1930 - S Colombia (base of Andes in from Meta S to Putumayo, and S Amazonas) S to NE Peru (N of R Amazon and R Marañón) and WC Amazonian Brazil (region immediately N of R Amazon and E to lower R Negro).
