Magellanic Cormorant

Leucocarbo magellanicus

With its striking red eye patches and elegant black-and-white plumage, the Magellanic Cormorant is a jewel of the rugged southern coastlines. Often seen perched on precarious cliffs, this master diver thrives in the wild, windswept waters of Patagonia and the Falklands.

Behavior

Magellanic Cormorants, also known as Rock Shags, are masters of the southern surf. Unlike many other cormorant species that congregate in massive, flat colonies, these birds prefer the rugged verticality of steep sea cliffs. They are exceptional divers, using their powerful webbed feet to propel themselves deep underwater in search of prey. While they are highly social during the breeding season, nesting in colonies that can number in the hundreds, they are generally less vocal than other seabirds, often communicating with subtle displays and guttural grunts near their nests.

When not foraging, you’ll frequently spot them standing on rocky outcroppings with their wings spread wide. This iconic posture helps dry their feathers, which aren't fully waterproof—an evolutionary trade-off that reduces buoyancy and allows them to dive deeper. In their interactions with humans, they are relatively wary and prefer inaccessible cliffs, though they have become accustomed to boat traffic in popular coastal regions like the Beagle Channel or the Falkland Islands.

Camera Tips

Capturing the Magellanic Cormorant requires focusing on their unique 'vertical' lifestyle. If you live along the rocky coasts of southern Chile or Argentina, position your camera facing steep, sheltered rock ledges where they are likely to nest or roost. Because these birds prefer inaccessible spots, a telephoto lens or a high-resolution trail camera is ideal for capturing detail from a distance. Aim for a height that looks slightly down or across at the ledge; looking up from water level often results in silhouetting against a bright sky, which obscures the beautiful detail of their glossy black feathers.

Lighting is your biggest challenge and best friend. The red facial skin and white throat patch provide excellent contrast, but the dark plumage can easily become a featureless silhouette in harsh midday sun. Set your camera to trigger during the 'Golden Hours'—shortly after sunrise or before sunset. This softer light brings out the iridescent blue-green sheen on their backs. Since they are strictly diurnal, you can save battery by disabling your camera's triggers during the night, focusing all your power on the high-activity window between dawn and dusk.

While you can't easily bait these marine birds into a 'backyard' in the traditional sense, you can take advantage of their habit of using the same 'drying stations' daily. Look for rocks or pier pilings covered in white guano; these are preferred sunning spots. Secure your camera to a stable, salt-spray-resistant mount to prevent it from shaking in high coastal winds. Use a high shutter speed if your AI camera allows manual settings, as their movements when shaking water off their wings are incredibly fast and prone to motion blur.

During the breeding months of October through January, focus your efforts on shelf-like rock formations. Magellanic Cormorants are creatures of habit and will return to the exact same nesting spot year after year. If you find a colony, keep a respectful distance—at least 15–20 meters—and use the camera's motion detection to capture their fascinating social interactions, such as 'sky-pointing' displays where they stretch their necks upward to signal to their mates. This long-term monitoring can provide a window into their nesting success and chick-rearing habits.

Frequently Asked Questions

Magellanic Cormorant are strictly diurnal, meaning they are active during daylight hours. They typically leave their roosts at dawn to forage at sea, with peak activity occurring in the mid-morning and late afternoon as they return to rocky ledges to dry their wings and socialize.
Because they are marine birds, you cannot attract them to a typical inland garden. However, if you have a coastal property with rocky shorelines or a private pier, providing undisturbed perching areas or 'drying rocks' free from human or pet traffic is the best way to encourage them to visit your viewable area.
They are specialized benthic feeders, meaning they hunt along the seafloor. Their diet consists mainly of small fish, such as blennies and rock cod, along with marine invertebrates like crustaceans and octopuses caught during deep dives.
They are generally not found in suburban neighborhoods unless those areas are directly adjacent to rocky marine environments. They are most common in wild, coastal regions of southern Chile, Argentina, and the Falkland Islands, though they may visit coastal harbors and jetties.
The Magellanic Cormorant is smaller and has a distinctive red patch of bare skin around the eye, whereas the Imperial Shag (or Blue-eyed Shag) has a blue eye-ring and a yellow fleshy growth (caruncle) at the base of its bill. Additionally, the Magellanic's white throat patch is more restricted.
