Great Horned Owls are the heaviest owls in North America, and are found throughout much of the United States, even living near people. They live in forests or field edges, and are generally nocturnal. 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.
