Behavior

Short-billed Gulls are noticeably more social and less aggressive than the larger 'four-year' gulls like the Glaucous-winged Gull. They are agile fliers and often gather in large, tight-knit flocks, particularly during the winter months when they descend upon coastal mudflats, estuaries, and even flooded suburban parks. You will often see them performing a 'foot-pattering' dance on wet grass or sand to bring invertebrates to the surface.

Unlike their more urban-adapted cousins, Short-billed Gulls tend to be slightly more wary of direct human contact, though they are frequent visitors to backyard feeders near the coast. They exhibit a complex range of vocalizations, including high-pitched, squealing 'kew' notes that lack the harshness of the larger gull species. During the breeding season, they are unique among North American gulls for their tendency to occasionally nest in trees near northern lakes.

Camera Tips

To capture the best footage of a Short-billed Gull, place your camera at a very low angle, ideally no more than 6 to 12 inches off the ground. Since these gulls spend a significant amount of time walking and foraging on the ground—especially on lawns or near the shoreline—a low perspective provides an intimate, 'eye-level' view that captures the detail of their small bill and expressive dark eyes. If you have a flat, open space in your yard, stake your camera near a low-profile birdbath or a shallow water feature, as they are frequently drawn to freshwater for drinking and bathing.

When it comes to camera settings, speed is your friend. Short-billed Gulls are highly active and can be skittish; set your PIR sensor to 'High' sensitivity and reduce the trigger delay to the shortest possible interval (ideally under 0.5 seconds). Because their white plumage can easily 'blow out' and lose detail in bright sunlight, try to position the camera so the sun is at its back, or use an exposure compensation setting of -0.3 or -0.7 if your camera allows it. This ensures the subtle gray-to-white gradients on their wings are preserved.

In terms of lures, you don't necessarily need birdseed. These gulls are highly attracted to shallow, splashing water or even 'shiny' objects. A slow-dripping water source can be an irresistible draw. If you are in a suburban setting, they are most likely to visit after a heavy rain when worms come to the surface. Timing your camera deployment to coincide with winter rainstorms in the Pacific Northwest will dramatically increase your capture rate. During these times, they are less picky and will often spend hours foraging in front of a well-placed lens.

Frequently Asked Questions

Short-billed Gulls are strictly diurnal, with peak activity occurring in the early morning and late afternoon. They are particularly active during low tide cycles in coastal areas or immediately following rainstorms in suburban environments.

The best way to attract Short-billed Gulls is by providing a large, shallow water source or a birdbath on the ground. They are also drawn to open, flat lawn areas, especially after irrigation or rain which brings worms and insects to the surface.

Their diet is highly varied, including small fish, insects, marine invertebrates, and even berries. In suburban backyards, they primarily forage for earthworms and grubs in the soil.

Yes, during the winter months, they are very common in suburban parks, schoolyards, and large backyards across the Pacific Northwest and along the California coast.

The easiest way to tell them apart is the bill: the Short-billed Gull has a small, plain yellow-green bill, while the Ring-billed Gull has a distinct black ring near the tip. Additionally, the Short-billed Gull has dark eyes, whereas the adult Ring-billed Gull has bright yellow eyes.
