Utah State Bird

California Gull

(Larus californious)

Adopted on February 14, 1955.

The California gull, Larus californicus, became the official state bird on February 14, 1955, when House Bill 51 was signed into law by Gov. J Bracken Lee (Utah Code 63-13-9). The bill was introduced by Richard C. Howe a member of the House of Representatives.

The gull was first protected under Utah law because it is an insectivorous bird (feeds on insects). It was protected along with the owl, hawk, lark, whippoorwill, thrush, swallow, snowbird, and any other insectivorous or song birds. The California gull was chosen as the state bird because it was credited with saving the pioneer's crops from complete destruction in the summer of 1848. The California Gull is the "seagull" that came to the aid of Mormon settlers in Utah, helping rid their crops of a plague of grasshoppers. A golden statue in Salt Lake City commemorates the event, and in recognition the California Gull was made the state bird of Utah.

Description of the Utah State Bird

Chiefly found in the interior regions, the California gull breeds on inland lakes from Canada south to Mono Lake, California, Great Salt Lake, and Yellowstone Lake, Wyoming. It winters along the Pacific Coast and inland in Utah, Oregon, and California. The mature California gull measures from twenty to twenty-three inches in length and has greenish yellow feet, a medium gray mantle, and a bill with an orange spot near the tip of the lower mandible. The outer primaries are black, tipped with white, the first two with subterminal white spots.

The gull is about two feet long. The color of this bird is pearly-blue. It is sometimes barred or streaked with blackish gray. Aeronautic wizards, gulls are gymnasts of the sky, making the seemingly impossible appear effortless. They can appear motionless in midair by catching wind currents with perfect timing and precision while positioning their bodies at just the right angle. They are quiet birds, considered quite beneficial by agriculturalists, and are usually gentle creatures, exhibiting neither antagonism to nor fondness for man.
