The Ash-Colored Tapaculo is known from the West Coast of northern South America 

Physical Description: The Ash-Colored Tapaculo is a medium sized perching bird, about 14 centimeters long with the males slightly heavier than the females. They are dark grey all over, with the bellies and chests a lighter grey than the backs, and the wings and tails a darker grey overall still. They have darker grey patches on their cheeks and heads. They also have brown feathers on their butts! Their beaks are small and pointy, and also grey.

Diet: The Ash-Colored Tapaculo doesn’t actually have a documented diet.

Behavior: The Ash-Colored Tapaculo spends much of its time hopping and creeping through dense tangles of foliage, usually near the ground. They don’t migrate for food, but stay in the same range year-round. The males only give seasonal calls in the breeding season, usually piercing “tick” sounds, followed by repeated trills that increase in volume. They breed in June through August, usually only laying one clutch.

Ecosystem: These birds live only in bamboo thickets and cane in humid mountain forests, usually at high elevations - between 2000 and 4000 meters up.

Other: The Ash-Colored Tapaculo isn’t threatened with extinction, and despite its somewhat restricted range is actually quite common, especially in some protected areas. However, they are dependent on certain plants for their habitats, and thus are vulnerable to some extent.
