Blassbauch-Erdhacker Tarphonomus harterti

Medium-sized brown bird of the ground and understory of thorn forest in Bolivia’s lower interandean valleys, though occurs locally at higher elevations. In most of range, the only earthcreeper. Prefers dense understory more than other species of earthcreeper. More often heard than seen, but not hard to find once the dry staccato song is learned.
