California Gull
Larus californicusAlso known as Mormon Gull
California gulls are highly adaptable, medium-sized seabirds famous for their graceful flight and bold, opportunistic foraging habits. They nest in large, noisy colonies on inland islands and lakes before migrating to Pacific coastal beaches and estuaries for the winter. These gulls played a historic role in Utah's agricultural history by consuming swarms of crop-destroying crickets, earning them a place of honor as Utah's state bird.

Responsible observation
- Identify by the bill: Look for a black spot and a red spot near the tip of the lower mandible on adults.
