Ash-coloured Tapaculo vs Rufous-vented Tapaculo

In short

The Ash-colored Tapaculo and Rufous-vented Tapaculo are both small, elusive birds of the montane forests, but they can be distinguished by their vent coloration and subtle differences in behavior. The Ash-colored Tapaculo has a more uniformly gray appearance, while the Rufous-vented Tapaculo features a distinctive rufous vent.
