Typical Antbirds (Thamnophilidae)

Giant Antshrike (Batara cinerea) - HBW 8, p. 534

French: Batara géant German: Riesenameisenwürger Spanish: Batará Gigante

Taxonomy: Tamnophilus [sic] cinereus Vieillot, 1819, Rio de Janeiro, Brazil.
Genus presumed related to Thamnophilus on basis of external morphology, especially the strongly hooked bill, but supporting molecular or other evidence unavailable. Relationships uncertain; possibly closest to the Thamnophilus doliatus complex. Populations in Bolivia, W Paraguay and NW Argentina require study; recent specimens from presumed range of race argentina (in E Bolivia lowlands) approach excubitor in paleness, and plumage differences between the two may be clinal; also, diagnosable differences may possibly be found between lowland and foothill populations...

Populations in Bolivia, W Paraguay and NW Argentina require study; recent specimens from presumed range of race argentina (in E Bolivia lowlands) approach excubitor in paleness, and plumage differences between the two may be clinal; also, diagnosable differences may possibly be found between lowland and foothill populations. Three subspecies recognized.
