Description: Hand-colored lithograph by J.T. Bowen after painting by John James Audubon. (Royal Octavo) 26.4x16.7 cm (10½x6½").Plate 313 from fascicle 63 in the Royal Octavo edition. According to the U.S. Fish & Wildlife Service who keep the endangered species list "The whooping crane (Grus americana) occurs only in North America, specifically within Canada and the United States, and is North America's tallest bird. It is a flagship species for the wildlife conservation movement in North America, as it symbolizes the struggle for survival that characterizes endangered species worldwide, as was noted in the international recovery plan in 2007.
Historically, more than 10,000 whooping cranes once populated North America. Its north to south range included Canada and the United State to Mexico, and its east to west range included the Rocky Mountains to the East Coast, as documented in the 5-year review in 2011. Population declines were caused primarily by shooting and destruction of habitat in the prairies from agricultural development, as was noted in the international recovery plan in 2007. The international recovery plan also notes that all whooping cranes alive today have come from the all-time low of 15 whooping cranes that were wintering at Aransas National Wildlife Refuge in Austwell, Texas in 1941."
