Other forms: seagulls
A seagull is a common, noisy shorebird. If a bird swoops down and steals your French fries as you're walking along the boardwalk, it was probably a seagull.
Although the large gray and white birds that follow lobster boats and congregate on beaches are officially called gulls, most people use the colloquial seagull. These sea birds have wide wingspans and webbed feet. They live in large groups and thrive alongside humans, scavenging trash and food waste in addition to eating fish and crustaceans. Described as "opportunistic feeders," seagulls are also highly adept at stealing the fish and chips right off your tray.
