Spot-bellied Eagle-Owl Ketupa nipalensis

Immense and imposing owl of dense wet lowland and hill forests. Silver-gray adult is majestic, with a large yellow bill, black eyes, and sweeping sidewards-facing “horns.” Juvenile is much paler, almost white, with shorter tufts. Gives deep echoing hoots. Primarily nocturnal, but will on occasion hunt by day; takes prey as large as small deer.
