Красногрудый скрытохвост Crypturellus variegatus

Secretive chickenlike bird that walks on the ground inside forest. Very plump; looks tailless. A relatively small tinamou with a striking pattern: look for bright rufous neck contrasting with blackish upperparts distinctly barred with buff. Fairly common and widespread from western Amazonia to southeast Brazil, although it is rarely seen in dense understory of terra firme forest. Listen for its whistled song, a single long note followed by a pause and then a series of shorter querulous rising notes.
