Normally, it excretes by leaning forward and slightly raising its tail, with the waste either going straight down or slightly backward. In the 1930s populations were about 20,000, but today only about 5500 nesting pairs remain. They fledge 60 to 65 days after hatching,[17] and reach sexual maturity at four years of age, although they usually do not successfully fledge chicks until their fifth year of age. The frequency at which it is added decreases after the eggs hatch. This greenery functions to help insulate the nest. The sexes are similar. [20] On the tree itself, forks of large limbs or places where multiple branches cross are usually chosen. A U.S. They fledge 60 to 65 days after hatching, although only about 31% of nests fledge a chick in any given year, with most chicks dying during their first two weeks, despite being watched by an adult during that time. The excrement aimed at the legs is fluid and watery. In … [12] Regional names include "flinthead", "stonehead", "ironhead", "gourdhead", and "preacher". [15] The head and neck of the adult are bare, and the scaly skin is a dark grey. Hunting and egg-collecting by humans has been implicated as a factor in the decline of South American wood storks. The availability of suitable feeding areas has been reduced due to draining of wetlands, flood control practices, land development, and lumbering. In 2004, the Florida Fish and Wildlife Conservation Commission (FWC) declassified the word stork from “Endangered” to “Threatened” as the wood stork experienced a slight upward trend in its population. In the dry season, this stork prefers to forage in waters with no emergent vegetation, whereas in the wet season, it prefers areas with vegetation emerging between 10 and 20 centimetres (3.9 and 7.9 in) above the surface on average. Large, white Wood Storks wade through southeastern swamps and wetlands. This is North America's only breeding stork, and the U.S. population is now federally listed as Threatened, downlisted from Endangered in 2014 due to some population recovery.

[39] It is likely that the Paraná River region's wetlands served as a stronghold of the species, from where it is now re-colonizing some of its former haunts. Predators of the wood stork include raccoons (which predate on chicks), crested caracaras, which prey on eggs, and other birds of prey, which feed on eggs and chicks. [12], This stork is able to adapt to a variety of tropical and subtropical wetland habitats[19] having fluctuating water levels (as that initiates breeding). [19] It nests colonially, with up to 25 nests in one tree. Fish and Wildlife Service downlisted the species from Endangered to Threatened status.) In the United States, on the other hand, it is considered to be threatened. Until then, threatened species receive essentially the same legal protections as endangered animals. [33] In hot weather, breeding adults will also shade their chicks with their wings. The amount of food that the chicks get changes over time, with more being fed daily from hatching to about 22 days, when food intake levels off. Drum plaza along the Florida Turnpike, Cortada ’s “ Endangered Animals ” series allowed the artist an opportunity to showcase a variety of endangered animals that have been affected by habitat loss due to overdevelopment. Endangered Species List. After a few hours of incubation, this bird sometimes takes a break to stretch, preen itself, rearrange nest material, or turn the eggs. Storks were once more abundant in the wetlands of south Florida than in any other region throughout the southeastern states. The wood stork is a large, long legged wading bird that reaches a length of 35-45 inches (89-114 centimeters) with a wingspan of 60-65 inches (152-165 centimeters). If only one stork is attending the nest when it is forced out, then it usually waits for its mate to try to take the nest back over. In South America, it is resident, but in North America, it may disperse as far as Florida. Breeding Population (Federal Register, February 28, 1984) Description:Wood storks are large, long-legged wading birds, about 45 inches tall, with a wingspan of 60 to 65 inches.
