State Bird: California These game birds have black throats circled in white and black plumes (males) on the top of their heads. The WatchList birds spend most of their time at ground level, seeking food. Nests are usually found at ground level. 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.
