Behavior

American Herring Gulls are highly intelligent and socially complex birds often seen in large, noisy colonies. They are masters of opportunistic foraging, displaying a remarkable ability to learn new food sources, including following fishing boats or frequenting urban landfills. While they are often viewed as simple scavengers, they are also skilled hunters, capable of diving for fish or dropping hard-shelled mollusks onto rocks or pavement from high altitudes to crack them open.

These gulls are quite vocal, using a wide array of 'trumpeting' calls to defend territory or communicate with mates. In suburban environments, they have become remarkably bold, often nesting on flat rooftops and successfully navigating human traffic. Despite their reputation for stealing snacks at the beach, they maintain a strict social hierarchy within their flocks and are devoted parents, with both sexes sharing incubation and chick-rearing duties.

Camera Tips

To capture the best footage of an American Herring Gull, place your camera in an open, flat area where the birds are known to congregate, such as near a shoreline, a large backyard pond, or even a flat rooftop if accessible. Because these birds are quite large and ground-oriented when not in flight, a camera height of 12 to 18 inches off the ground provides an intimate, eye-level perspective that highlights their piercing yellow eyes and powerful bills. Use a wide-angle lens setting if your AI camera supports it, as these gulls have a significant wingspan that can easily be cut off in tight frames.

Lighting is your biggest challenge when photographing gulls due to their bright white plumage. On sunny days, the white feathers can 'blow out' or lose detail in the highlights. Position your camera with the sun at your back to evenly illuminate the bird, or better yet, aim for 'golden hour' (shortly after sunrise or before sunset) when the light is softer and warmer. If your camera allows for exposure adjustment, consider underexposing by a half-stop to preserve the texture in their white feathers.

While we don't recommend feeding wildlife, you can attract them to a specific 'stage' in front of your camera by providing a fresh water source. A large, shallow birdbath or a slow-dripping water feature is irresistible to gulls for both drinking and bathing. This behavior makes for excellent video content, as they will splash vigorously, providing a dynamic look at their feather structure. If you are in a suburban area, placing the camera near a consistent perching spot—like a fence post or a large rock—will help you capture steady, high-detail portraits.

Finally, keep your shutter speed or frame rate high. Gulls are fast movers, especially during take-off or when competing for a resource. A higher frame rate (60fps) will allow you to capture the mechanics of their flight in smooth slow-motion. During the winter months, look for 'roosting' behavior where they tuck their beaks into their feathers; this is a great time to capture still, high-resolution images while the bird is stationary for long periods.

Frequently Asked Questions

They are diurnal birds, most active from dawn until dusk. Their peak activity typically occurs in the early morning and late afternoon when they are actively foraging for food and moving between roosting and feeding sites.

The most effective way to attract them is with a large, clean water source. A ground-level birdbath or a small pond will encourage them to land for drinking and bathing, especially if you live within a few miles of the coast or a large lake.

They are omnivores with a very diverse diet. In the wild, they eat fish, crabs, and clams. In human-populated areas, they are opportunistic scavengers that will eat almost any organic waste, though they prefer high-protein sources like fish scraps.

Yes, they are highly adaptable and have become common in suburbs, particularly those with large shopping centers, landfills, or flat-roofed buildings which they use as safe nesting sites away from ground predators.

The easiest way is to look at the legs and the bill. American Herring Gulls are larger with pink legs and a red spot on the lower bill. Ring-billed Gulls are smaller, have yellow-green legs, and a distinctive black ring encircling the bill.
