The Brown Fish-Owl (Ketupa zeylonensis) is a large owl species found in Sri Lanka, distinguished by its prominent ear tufts and rufous-brown plumage. Unlike most owls, it primarily hunts fish and crustaceans from slow-moving rivers and streams, showcasing a specialized hunting technique. Its deep hooting calls echo through the night, adding to the mystique of its presence in the island’s forested and wetland areas. These owls are typically solitary and secretive, making them a captivating sight for birdwatchers and nature enthusiasts.
