The Crested Owl is a distinctive forest owl with spectacular, protruding white ear tufts that contrast with its otherwise dark plumage. It is most often detected by call, a deep, rolling growl repeated regularly.

​​

It often occurs at forest edges and clearings or along watercourses, where it apparently forages for large arthropods and perhaps small vertebrates.
