Strix nigrolineata
The black-and-white owl is a medium-sized owl with a round head and no ear tufts. It is between 35 and 40 cm in length and weigh between 400 and 535 grams. As for most owl species, females are usually bigger than males with an average weight of 487 g and 418 g respectively. It has a striped black-and-white breast, belly, and vent. With the exception of a black-and white striped collar, the upperparts from the crown to the tail are a sooty black. The facial disc is mostly sooty black, with white "eyebrows" that extend from the bill to the collar. Voice: Its call consists of a series of rapid, guttural, low calls, followed by a short pause and a low, airy call and a faint, short hoot. Occasionally, it is shortened to just the last two notes, leaving out the opening series. Moreover, the female's call usually sounds louder than the male's and individuals make fainter "hoots" near their nest.
