Trachycephalus cunauaru

It is endemic to Brazil, Bolivia, and Ecuador, where it lives in rainforest and other forest habitats.

This frog has a pattern of dark and light brown or gray on its back.

The male frog finds a water-filled hole or cavity inside a tree.

Then it perches between 2 and 32 meters off the ground and sings to attract a female, who lays her eggs in the water.

Scientists believe the frogs are territorial and may compete for good nesting sites.
