Wild Republic has been producing its Audubon Birds Series for 20 years. Many of their birds with song have been retired, but the more popular types are still being made. These little plush Coastal birds are 6 to 8 inches long and sing their own particular song when squeezed.They are made by Wild Republic in partnership with the Audubon Society. The bird sound recordings are made by the Cornell Lab of Ornithology. Unfortunately, none of these Coastal Birds are being made.
