Anjouan Scops-Owl Otus capnodes

Small, compact dark owl with tiny ear tufts that are often invisible. The overall coloration can be blackish-brown or rufous-brown. Found in remnant rainforest and secondary forest on the island of Anjouan, in the Comoros. The remarkable vocalization, very different from that of a typical scops-owl, is a series of several mournful, descending whistles, each similar to the flight call of Black-bellied Plover. Sometimes two or more birds duet. Easily identified, as the only other owl on Anjouan is the much larger Barn Owl.
