Here’s a ring-billed gull I found in the park. They’re not hard to find.
According to the Cornell Lab of Ornithology:
Ring-billed Gulls are often found in and around urban, suburban, and agricultural areas. In coastal areas, Ring-billed Gulls frequent estuaries, beaches, mudflats, and coastal waters. In winter, these birds are common around docks, wharves, and harbors. Ring-billed Gulls are more commonly seen inland than most other gull species. They can be found at reservoirs, lakes, ponds, streams, landfills, parking lots, and shopping malls.
