Yungas Pygmy Owl
The Yungas Pygmy Owl ( Glaucidium bolivianum ) is a small owl species of the genus Sperlingskäuze. It is found only in South America.
Appearance
The Yungas Pygmy Owl reaches a height of about 16 centimeters. Ear tufts are missing. The species occurs in a gray, brown and red-brown color morph. The Occipitalgesicht is striking. The crown is dense whitish mottled and has occasionally also some elongated spots on. Even the back is spotted tight. The underparts are whitish with dark spots on the upper sides of the chest.
