Status
The IUCN has assessed the unicolored tapaculo as being near threatened. However, although it is fairly common within its very small range and appears to tolerate disturbance, its habitat is very fragmented and at risk from fire. It "probably merits the conservation status of Near-threatened, or even that of Vulnerable."
