Utah State Bird: California Gull

The gull is tied to the defining survival story of Utah's pioneer settlement. Settlers faced starvation during their first full harvest season. Cricket destruction of crops would have meant death through winter. Gull arrival at the critical moment became known as the Miracle of the Gulls — a story that passed through generations and shaped Utah's founding identity. The Sea Gull Monument in Temple Square, erected in 1913, keeps that memory visible in the state's most visited public space.

Farmers valued gulls as beneficial pest controllers. The birds ate grasshoppers, beetles, and rodents from agricultural fields. They follow plows to pick up insects turned over by machinery, and have been observed waiting near irrigation channels for rodents flushed from their holes. This practical utility reinforced the gull's positive standing in Utah's agricultural communities well beyond the 1848 event.

Salt Lake City's Sea Gull Monument commemorates the 1848 event. Two bronze gulls perch atop a granite column in Temple Square. The inscription reads that gulls saved pioneers from starvation by feeding on crickets. Dedicated in 1913, the monument predated official state bird designation by 42 years.

Adults measure eighteen to twenty-two inches long. Wingspan ranges from forty-eight to fifty-four inches when extended. Weight varies from one pound to just over two pounds. Males run larger than females by six to ten percent in skeletal measurements. Bill appears parallel-sided without the expansion at the gonydeal angle seen in other gulls.

Breeding adults show white heads, necks, and underparts. The back and upper wings display slate-gray coloring darker than ring-billed gulls. Black wingtips feature white spots at the tips. Bills are yellow with a black ring near the tip plus a red spot on the lower mandible. Dark brown eyes contrast with bright red orbital rings. Greenish-yellow legs complete the appearance.

First-year juveniles appear mottled brown and white overall. Pink legs and bills with black tips mark young birds. Second-year gulls begin showing gray on the back while retaining brown mottling. Blue tint appears on legs and bill base. Third-year birds resemble adults closely but lack fully developed bill and wing patterns. Full adult plumage arrives in the fourth year.

Size falls between smaller ring-billed gulls and larger herring gulls. Dark eyes distinguish California Gulls from herring gulls. More extensive black on wingtips creates a nearly square-cut shape compared to similar species. Round head and slender bill help separate them from herring gulls in flight.

The main call consists of repetitive kee-yah notes. First two notes stretch longer and more drawn out than later ones. Pitch runs higher than corresponding herring gull calls. Voice quality sounds hoarse and scratchy rather than clear. Breeding colonies create constant noise from gulls defending territories against neighbors.

California Gulls use multiple foraging strategies. They walk and wade through shallow water picking up prey, swim while grabbing food from the surface, and swoop down from flight to snatch items. Agricultural areas attract them to follow plows for exposed insects and rodents.

Highly gregarious birds gather in flocks numbering thousands. Colony nesting brings concentrations of 4,000 nests per football field at major sites. Mono Lake hosts 44,000 to 65,000 California Gulls arriving each April. Great Salt Lake supports even larger numbers. Dense nesting means neighbors position within two feet of each other.

Breeding gulls defend nest areas aggressively. They stretch necks straight up and open bills to chase intruders. Constant screaming fills colonies as birds protect territories. Despite social nature outside breeding season, territorial behavior prevents other gulls from approaching active nests closely.

Nesting occurs around interior lakes and marshes from Northwest Territories south to eastern California and Colorado. Great Salt Lake historically held eighty percent of breeding California Gulls before the 1930s. Mono Lake in California hosts the second-largest colony. New breeding colonies established on reservoirs built across the West after 1930.

Most populations migrate to the Pacific Coast for winter. Some birds remain at interior sites year-round where water stays open. Juveniles sometimes stay coastal through summer instead of returning to breeding grounds. Spring migration brings birds back to colonies three to seven weeks before egg laying begins.

Great Salt Lake remains the primary breeding location. Colonies nest on islands safe from land predators, where brine flies hatching in large numbers provide rich food sources. Urban gulls also feed at garbage dumps around Salt Lake City and other population centers, and agricultural lands throughout Utah attract foraging birds throughout the breeding season.

Sparsely vegetated islands and levees in saline lakes provide ideal breeding sites. Harsh conditions tolerated by California Gulls exclude ring-billed and herring gulls from some locations. Winter habitat includes seacoasts, estuaries, mudflats, beaches, and farmland. Garbage dumps supply food year-round near cities.
