Behavior

The Northern Gannet is the undisputed heavy-hitter of the North Atlantic skies. These birds are most famous for their breathtaking hunting displays, where they soar to heights of 100 feet before folding their wings and plummeting into the sea at speeds reaching 60 mph. To survive these high-velocity impacts, they possess specialized air sacs beneath the skin of their face and chest that act like a car's airbag, cushioning the blow as they hit the water.

Socially, gannets are highly colonial, gathering in the thousands on sheer coastal cliffs to breed. While they are graceful and silent in flight, their nesting colonies are a cacophony of guttural calls and bill-clattering displays. They are fiercely territorial of their nest sites, but at sea, they can be seen following fishing vessels or joining pods of dolphins to capitalize on schools of fish pushed to the surface.

Camera Tips

Capturing the Northern Gannet on camera is a thrilling challenge, primarily because they are masters of the open ocean. If you are lucky enough to have a coastal overlook or cliffside property, position your camera facing the water or toward known flight paths. Because these birds are brilliantly white, they often 'blow out' in direct sunlight, losing all feather detail. To prevent this, manually adjust your camera's exposure compensation to -1.0 or -2.0; this keeps the whites crisp and reveals the subtle golden hues on their heads.

The action happens fast. If you are using a trigger-based trail camera, set it to the highest possible sensitivity and use 'Burst Mode' or 'Multi-Shot.' A Northern Gannet's plunge dive is over in a fraction of a second, and a single photo rarely captures the drama. If your camera settings allow for it, prioritize a fast shutter speed (at least 1/2000s) to freeze the bird mid-air. For video, 60fps or higher is ideal so you can slow down the footage to appreciate the mechanics of their dive.

Since you cannot use traditional bait to attract a gannet, you must rely on their natural patterns. They are most active when the tide is turning and baitfish are moving. During the breeding season, look for 'flight lines'—consistent paths the birds take from the colony to the fishing grounds. Mounting your camera 4-6 feet high on a sturdy post or tripod will give you the best angle on the horizon. Finally, remember that salt spray is the enemy of electronics; always use a weather-sealed housing and wipe the lens with a microfiber cloth daily to ensure your shots remain crystal clear.

Similar Species

Species that look similar or are commonly confused with Northern Gannet.

Northern Fulmar

Much smaller with a 'tubeneose' bill and stiffer wingbeats; lacks the gannet's black wingtips and golden head.

Great Black-backed Gull

Has a dark mantle (back) and wings, whereas the gannet is almost entirely white with only black wingtips.

Masked Booby

Found in tropical waters rather than the North Atlantic; has a much more extensive black mask and a different tail shape.

Frequently Asked Questions

Northern Gannets are strictly diurnal, meaning they are active during daylight hours. Their peak hunting times often coincide with dawn and dusk when fish move closer to the surface, though they will dive all day if food is plentiful.

Unless your 'backyard' is a cliff overlooking the North Atlantic, you won't be able to attract them with food or houses. They are pelagic birds that live at sea. Coastal residents can encourage sightings by maintaining clear views of the ocean and watching for schools of fish that draw them in.

They are specialized piscivores, meaning they eat fish. Their favorites include fatty, energy-rich species like Atlantic mackerel, herring, and capelin, which they catch by diving deep into the water column.

No, they are almost never seen in suburban or inland areas. They are highly maritime birds that only come to land to breed on specific, remote rocky islands or mainland cliffs.

Northern Gannets are significantly larger than any gull, with much longer, narrower wings and a pointed tail. Their dagger-like bill and the way they plunge vertically into the water are dead giveaways that you aren't looking at a common gull.
