The Andaman scops owl (Otus balli) is a species of the Strigidae family and is native to the Andaman Islands of India. It is a largely brown owl with white speckles and yellow eyes. The owl was first described in 1873 by British ornithologist Allan Octavian Hume. The Andaman scops owl has no sightings outside of the Andaman Islands, therefore research on this bird is limited. This owl is not threatened, though an increase in deforestation on the islands has led to the population size slowly declining. It is a nocturnal owl that feeds at night and has a nesting season from February to April.
