What primary difference in habitat adaptation exists between the Ivory-billed Woodpecker and the Pileated Woodpecker?

Answer

The Ivory-bill's specialized dependence on pristine, unmanaged forest structures contrasted sharply with the Pileated Woodpecker's ability to utilize more generalist habitats, including secondary growth.
