Typical Antbirds (Thamnophilidae) - HBW 8
Bicoloured Antvireo (Dysithamnus occidentalis)
French: Batara occidental
German: Schiefergrauer Würgerling
Spanish: Batarito Bicolor
Other common names: Western Antvireo/Antshrike, Chapman’s Antvireo/Antshrike
Taxonomy: Thamnophilus aethiops occidentalis Chapman, 1923, Cocal, 4000 ft [c. 1200 m], Cauca, Colombia.
Relationships of genus not clearly established; preliminary molecular evidence suggests affiliation with Thamnophilus, and morphological characteristics have connected it with Thamnomanes. Present species has been variously allocated to both of those genera, but bulk of vocal, morphological and ecological evidence supports its inclusion in current genus. Racial identity of birds on Pacific slope in N Ecuador uncertain; tentatively placed in nominate, but possibly belong to race punctitectus. Two subspecies recognized.
Subspecies and Distribution:
- occidentalis (Chapman, 1923) - Pacific Andean slope of S Colombia (Valle, Cauca) and extreme N Ecuador (Carchi).
- punctitectus Chapman, 1924 - E Andean slope in Ecuador (Napo, Morona-Santiago).
