The Rock Earth Tyrant is a small gray bird. It lives high in the mountains of South America and catches insects among rocks and grass.
The rock ground tyrant differs from related species by living at very high altitudes among stones. It is important for nature because it eats harmful insects and serves as food for mountain predators.
