A big owl with white face. Usually active at night and can be easily detected by unique and scary sounds. That one found this morning (Jakarta) after my friend shown me. They tell me that the bird fall down from the faculty building, and not able to fly again. They release in the roof of the corridor and then this bird stay cool on the top of it.
There are two owl in my campus - the first is T. alba and the second from genus Otus. Otus has very different with this one.
