Blaugrau-Ameisenvogel

Bestimmung

The bluish-slate antshrike is 13.5 to 14.5 cm (5.3 to 5.7 in) long and weighs 16 to 18 g (0.56 to 0.63 oz). Adult males of the nominate subspecies are almost entirely darkish gray; they have a hidden white patch between the scapulars. Adult females' upperparts and throat are a slightly browner and paler gray than the male's. Their ear coverts and throat have thin white streaks. Their belly and flanks are deep cinnamon-rufous. Subpecies T. s. intermedius is darker overall than the nominate.

Taxonomie

The bluish-slate antshrike has two subspecies, the nominate T. s. schistogynus (Hellmayr, 1911) and T. s. intermedius (Carriker, 1935). Some early twentieth century authors treated the bluish-slate antshrike and the cinereous antshrike (T. caesius) as conspecific. They now are considered a superspecies.

Subspecies T. s. intermedius is found in central Peru from south of the Amazon and east of the Huallaga River south to Junín. The species inhabits inhabits the understorey to mid-storey of terra firme and várzea evergreen forest, where it favors areas with much bamboo and vine tangles.
