Spot-bellied Eagle-Owl
Ketupa nipalensis
The spot-bellied eagle-owl is a large species of owl. It measures from 50 to 65 cm (20 to 26 in) in length. It is the sixth longest owl in the world on average and has the ninth longest wings of any living owl. The widely reported weight range for this species is 1.3 to 1.5 kg (2.9 to 3.3 lb), but this is probably towards the low end (possibly from K. n. blighi) or is possibly representative only of smaller males. Voice: This owl is noted for its strange, human-sounding call, and it has been suggested that it is the same as the cryptid known as ulama or "Devil Bird" in Sri Lanka. A local name is Maha Bakamuna ("large horned owl"). According to http://www.cryptozoology.com, in July 2001 it was confirmed that ulama description perfectly matches spot-bellied eagle-owl.
