About These Birds
Barred Tinamou
A small tinamou with distinctly barred brown-and-buff plumage. Restricted to the Casiquiare region of Venezuela and adjacent northwestern Brazil—one of the most restricted tinamou ranges. Nearly all data come from specimens. Inhabits humid lowland forest along river systems.
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.
