A shy, uniformly chestnut-brown bird found in the foothills and lower slopes of Colombia’s Santa Marta Mountains. It lacks strong field marks, but has a rather stout bill and is slightly paler on the chin and around the eye. Always stays inside dense tangles in the forest understory, making it hard to see, and is heard much more often than it is seen. Song is a series of quick bursts of around five notes with an odd, nasal quality.
