A dense colony of Imperial Shags is active on a rocky coastline. Many birds are seen sitting on raised, mound-like nests made of mud and guano, while others stand or move through the crowd. There is significant movement as individuals adjust their positions, preen, and stretch their necks in social interactions.

A bustling scene at the coast where a large colony of Imperial Shags stands across the rocky terrain. Several Magellanic Penguins are interspersed within the group, waddling between the shags. In the background, South American Sea Lions are hauled out on the wet rocks as waves crash against the shore under a pale morning sky.

Geographic range
Where Does the Imperial Shag Live?
Native to the southernmost reaches of the Southern Hemisphere, the Imperial Shag thrives along the rugged coastlines of southern South America, specifically in Chile and Argentina. Its range extends across the cold waters of the Southern Ocean to the Antarctic Peninsula and various subantarctic island chains like the Falklands and South Georgia. These birds are iconic residents of the windswept Patagonian fjords and the icy fringes of the Antarctic continent.

Behavior
Imperial Shags are highly social and gregarious birds, often found in massive, noisy colonies that can number in the thousands. They are exceptional divers, utilizing their powerful webbed feet to propel themselves to incredible depths—sometimes reaching nearly 100 meters—in search of prey. Unlike many other seabirds, they are known to forage both individually and in synchronized groups called "rafts," where they work together to herd schools of fish toward the surface.
While they spend much of their time at sea, they are common sights along coastal settlements, often resting on man-made structures like piers, jetties, and harbor walls. Their social life is centered around the breeding colony, where they engage in elaborate ritualized displays, such as "head-shaking" and "sky-pointing," to strengthen pair bonds. They are generally tolerant of humans but will aggressively defend their small nesting territories from encroaching neighbors or scavengers.

Camera Tips
To capture the Imperial Shag on camera, focus on rocky outcrops or piers near the shoreline where they typically dry their wings. Because their feathers are not fully waterproof, they spend significant time perched with their wings spread wide to catch the wind. Positioning your camera at a low angle (about 1-2 feet off the ground) can create a dramatic perspective that highlights their striking blue eye-rings and yellow caruncles against the ocean backdrop.
Since these birds inhabit harsh, windy environments, ensure your camera housing is extremely weather-resistant and securely anchored to rocks or heavy driftwood. Avoid placing cameras in the direct splash zone to prevent salt spray from blurring the lens. If you are near a breeding colony, set your camera at a distance of at least 15-20 feet to avoid disturbing the birds; use a high-resolution sensor or a zoom-capable trail camera to get the best detail without causing stress.
The best time for activity is during the 'golden hours' of early morning or late afternoon when they return from foraging trips. Fast shutter speeds are essential (1/1000s or faster) if you hope to catch them in flight or as they explode out of the water. While they don't respond to traditional birdseed, placing a camera near a known 'drying rock' or a popular jetty is far more effective than any artificial lure.
