It is spread all throughout the country with heavy concentrations mostly in the southern part of the United States.

Wood Stork The Wood Stork is definitely a specialist. Its populations are seen exclusively in the South and the Southeastern parts of the country with its heaviest populations in Florida and more so in south Florida.
