About Agriornis murinus (Orbigny & Lafresnaye, 1837)
The lesser shrike-tyrant (scientific name Agriornis murinus) is 16 to 18.5 cm (6.3 to 7.3 in) long. Adult males have a gray-brown crown, mottled blackish and white lores, and a whitish or buffy supercilium and eye-ring. Their upperparts are gray-brown. Their wings are mostly dusky, with whitish tips on the coverts and whitish edges on the inner flight feathers. Their tail is mostly dusky, with pale grayish to white outer webs on the outermost pair of feathers. Their throat is white with thin black streaks, their breast is very pale grayish brown, their flanks are pale grayish brown with a buff tinge, and their belly is creamy whitish. Adult females have almost identical plumage to males, but the streaks on their throat are browner. Both sexes have a dark iris, a slender hooked black bill, and blackish legs and feet. The lesser shrike-tyrant is distributed from central Bolivia south through western Paraguay and Argentina to northern Santa Cruz Province. It has also been recorded as a vagrant in Brazil, Chile, and Uruguay. It inhabits open areas with scrubby bushes and scattered trees; in the northern part of its range it also lives in agricultural areas. Its elevational range extends from sea level to 2,500 m (8,200 ft), and it reaches this maximum elevation in Bolivia.
