Tawny-browed Owl

The tawny-browed owl is about 44 cm (17 in) long. Males weigh 405 to 562 g (14.3 to 19.8 oz) and females 331 to 670 g (11.7 to 23.6 oz). It has a brown facial disk surrounded by ochre, a white chin patch, and creamy "brows" over chestnut-brown eyes. Its breast, upperparts, and tail are dark chocolate brown, and the tail has white bars. The belly is buff and the rest of the underparts are light ochre. The juvenile is initially almost entirely white and gradually attains adult plumage over several years. Voice: The male tawny-browed owl makes a "ow, descending sequence of guttural, ventriloquial 'brrr brrr brrr brrr' or 'ut ut ut ut ut' notes, accelerating and weaker at end", to which the female responds with a higher pitched call.
