Dusky-throated Antshrike

The dusky-throated antshrike (Thamnomanes ardesiacus) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds".

The dusky-throated and saturnine antshrike (T. saturminus) were treated as conspecific by many twentieth century authors and now are considered to form a superspecies. The dusky-throated antshrike has two subspecies, the nominate T. a. ardesiacus (Sclater, PL & Salvin, 1868) and T. a. obidensis (Snethlage, E, 1914). == Description == The dusky-throated antshrike is 13 to 14 cm (5.1 to 5.5 in) long and weighs 16 to 19 g (0.56 to 0.67 oz).
