About These Birds
Berlepsch's Tinamou
A small tinamou with rich brown plumage and fine black barring. One of the least-known tinamous, restricted to Pacific lowland forests of Colombia and northwestern Ecuador. Largely understudied; known mainly from a handful of specimens. Terrestrial and secretive.
Solitary Tinamou
