If you see a gray bird in description on the beach islands off the coast of California and other North American states, then you are in the range of some of the most popular terns around - the Heerman's gull. This bird is also in shades of brown and other dull colors, so you can expect some range in their shades. These terns are born on beaches, staying close to the beach and the water for the rest of their life. Even when breeding adults come together for migration, or have calls to breed, you will see them coming back to beaches. They have a range all across North America, and with their brown, gray, and other colors, can easily blend into the environment, hiding from predators. If you want to know about these terns, particularly the Heermann's gull ages, Heermann's gull winter and when they breed, immature Heermann's gull flight and migration, and the Heermann's gull Arizona habitat, then do not forget to read on!
