About Pulsatrix koeniswaldiana (M.Bertoni & W.Bertoni, 1901)
The tawny-browed owl (Pulsatrix koeniswaldiana) is approximately 44 cm (17 inches) in length. Males weigh between 405 and 562 g (14.3 to 19.8 oz), while females weigh between 331 and 670 g (11.7 to 23.6 oz). It has a brown facial disc framed by ochre, a white patch on the chin, and creamy-colored "brows" above chestnut-brown eyes. Its breast, upperparts, and tail are dark chocolate brown, and the tail is marked with white bars. The belly is buff, and the remainder of the underparts are light ochre. Juvenile tawny-browed owls are almost entirely white when they are young, and gradually develop full adult plumage over the course of several years.
This owl species occurs in Brazil, ranging from Espírito Santo state south to northern Rio Grande do Sul, as well as in the immediately adjacent areas of eastern Paraguay and northeastern Argentina. It lives in humid tropical forest, open woodland, and forest dominated by Araucaria evergreens. Its elevational range extends from sea level up to approximately 1,500 m (4,900 ft).
