About These Birds
Small-billed Tinamou
A small tinamou with brown plumage, pale underparts, and a notably short fine bill. Widespread in cerrado, savanna woodlands, and forest edges of central South America. Often calls from dense grass or low scrub. One of the few tinamous adapted to open and semi-open habitats.
Highland Tinamou
