cormorant

Imagine a sleek, dark bird diving headfirst into the water—that's likely a cormorant! These fascinating waterbirds are skilled fishers, known for their dark, glossy feathers and their habit of spreading their wings to dry after a swim. They're often seen perched on rocks, buoys, or pilings near the coast (or by lakes and rivers), looking like shadowy guards. Cormorants aren't always welcomed by human fishermen, though—they have a very healthy appetite for fish! Historically, cormorants even played a role in Japanese and Chinese culture; skilled fishermen would train them to catch fish, keeping the birds on leashes and rewarding them with small portions of their catch.

A cormorant is a large, often dark-feathered waterbird found around the world on coasts, lakes, and rivers—on every continent except Antarctica. They belong to the family Phalacrocoracidae, a name that ultimately traces back to Greek words meaning "bald raven." This is a fitting description, as cormorants share the dark, alert look of a raven but are specialized for life in and around the water.

These birds are remarkable divers, able to plunge underwater and pursue fish with impressive speed and agility using their webbed feet for propulsion. Unlike many other seabirds, cormorants do not have fully waterproof feathers. While this might seem like a disadvantage, it is actually an evolutionary trade-off: by allowing their feathers to soak up some water, the birds reduce their natural buoyancy, which helps them stay submerged and maneuver with greater ease while hunting. After a dive, they must perch with their wings outstretched to dry in the breeze—a truly iconic and ancient-looking sight.

There are around 40 different species of cormorant, varying in size and habitat. Some live near freshwater lakes and rivers, while others prefer the rocky cliffs of the open ocean. Throughout history, they have had a complex relationship with humans. While admired for their incredible fishing skills, they have also been considered pests by those who fear competition for local fish stocks. In some cultures, such as in Japan, cormorant fishing (known as ukai) is a traditional practice dating back over a thousand years. Whether you see them as a rival or a marvel of nature, the cormorant remains a skilled hunter and a fascinating fixture of the world's waterways.
