The Larus or California gull (Larus californicus) is a medium-sized gull, smaller on average than the herring gull, but larger on average than the ring-billed gull.

It lives not just in California, but up and down the entire Western coast of North America, and has breeding ground inland. The yellow bill has a black ring.

Gulls are often thought of as coastal birds, but California Gulls are also common in inland areas in the West. These medium-sized gulls breed in colonies on islands and levees in lakes and rivers.

The L. californicis or California Gull, like most gulls, is an opportunist, eating anything it can catch or scavenge.

It has an odd foraging strategy for catching alkali flies that congregate on the shores of salty lakes in the Great Basin. It starts at one end of a huge raft of flies and runs through them with its head down and bill open, snapping them up along the way.

Both parents incubate the eggs, taking turns throughout the day at about 3–4 hour intervals. When it’s time to trade incubation duties, an adult flies into the nest area while calling. The incubating gull stands up and gives several “long calls” as its mate lands near the nest.

The returning mate joins in the calling and eventually takes over incubation duties. Sometimes the incubating bird isn’t ready to leave the nest, so the returning mate offers encouragement by giving the “choking call,” presenting nest material, or physically nudging its mate to get it off the nest.

In 1848, a plague of katydids (also known as Mormon crickets) began devouring the crops of Mormon settlers in Utah.

When California Gulls returned to breed, they started feasting on the katydids, saving the crops from complete destruction. A golden statue in Salt Lake City commemorates the event, and in recognition the California Gull was made the state bird of Utah.

The oldest recorded L. californicis or California Gull was at least 28 years old when it was caught due to an injury in California in 2013. It had been banded in the same state in 1985.
