A large owl of lowland and foothill forest, including secondary habitat and plantations. Warm brown with a heavily marked back, a heavily streaked rufous head and chest, and a more sparsely streaked pale belly. Note the square-shaped head with flattened ear tufts and the yellow eyes. Unmistakable. No other owls of similar size occur in its range. Gives a long, drawn-out, spooky whistled note whose pitch rises slightly, then falls at the end.
