Calliste à tête noire Stilpnia cyanoptera

Small bird of foothill forests. Males have a pale buffy body with black head, wings, and tail; females are much more drab, with a grayish-green head, pale bluish-green back, and yellowish underparts. In good light, both sexes show blue in flight feathers. Found in foothill forests and edge habitats, dry valleys, and in humid forest around the bases of the tepuis. Usually observed at fruiting trees, often in pairs or small family groups, from lower levels into canopy. Calls are indistinct chips and twitters. Plumage pattern of male is distinctive; females are more confusing but are seldom seen without males, facilitating identification; note contrasting gray head and (at close range) blue in wings.
