Ivory-billed Woodpecker
The Ivory-billed Woodpecker (Campephilus principalis) is a critically endangered, possibly extinct, woodpecker species native to the southeastern United States and Cuba. Renowned for its large size and striking appearance, it holds a near-legendary status among bird enthusiasts. Its ecological role was primarily as a specialist feeder on recently deceased trees, contributing to forest nutrient cycling. Culturally, the species has become a symbol of conservation and the devastating impact of habitat loss.
