Giant Wood Storks mating is a sight to behold! A Rookery with about two dozen Wood Storks in varying stages of mating, nest building and incubating is exciting to observe and also realize that this once endangered and now “threatened” stork is on the slow road to recovery.
Widespread in central and South America these storks are seriously impacted in the coastal southeast U.S. by continued habitat loss, with a few large protected rookeries such as this one in Palm Beach County, Florida at Wakodahatchee Wetlands making a big difference. Long telephoto lenses are critical as one should stay well away from nesting storks and not disturb them.
Tall and long-legged, the wood stork is the largest wading bird native to America. Wood storks are large, long-legged wading birds, about 45 inches tall, with a wingspan of 60 to 65 inches. The plumage is white except for black primaries and secondaries and a short black tail. The head and neck are largely unfeathered and dark gray in color. The bill is black, thick at the base, and slightly decurved. Immature birds have dingy gray feathers on their head and a yellowish bill.
This is a subtropical and tropical species which breeds in much of South America, Central America and the Caribbean. The wood stork is the only stork that presently breeds in North America. In the United States there is a small breeding population in Florida, Georgia, and South Carolina, along with a recently discovered rookery in southeastern North Carolina. After a successful three-decade conservation effort resulting in an increased population in the southeastern United States, the wood stork was removed from the endangered species list and upgraded to threatened on June 26, 2014.
