What requirement linked the survival of the Ivory-billed Woodpecker closely to the devastating effects of logging?

Answer

Their reliance on high-quality, old-growth timber for their specialized food source

The bird's specialized diet required trees in a specific stage of decay to harbor large grubs, meaning that logging of mature bottomland hardwoods eradicated their necessary food supply.
