State Bird: Utah Grateful Utah residents chose this as their state bird because they saved the Mormons' crops from locusts in 1848. California Gulls also feed on rodents, eggs, fish and garbage. They usually nest near freshwater lakes or marshes. Wild Republic has partnered with Audubon to create this line of genuine plush birds. Each bird's lifelike design and detailing is the result of input from Audubon. In addition, the authentic sound in each bird has been provided by the Cornell Lab of Ornithology and represents hours, months and even years of extensive fieldwork conducted by expert recordists. These Audubon Birds in this series vary in size but generally measure approximately 5 to 7 inches long.
