The Santa Marta Tapaculo is a range-restricted songbird endemic to northern Colombia. Found only in the Santa Marta Mountains of Colombia, the species inhabits undergrowth of montane humid forest between 1350 and 1700 meters in elevation. It is largely medium gray with a small white coronal patch, brown-marked rufous lower flanks, crissum, and rump. Santa Marta Tapaculo used to be considered a subspecies of Rufous-vented Tapaculo; however, the Santa Marta Tapaculo is smaller and paler gray than the wider-ranging Rufous-vented. This tapaculo’s song is a long, rapid trill.
