15 of Earth's Most Endangered Species
1. Ivory-Billed Woodpecker
One of the most endangered species known to man, the Ivory-Billed Woodpecker resides in the Southeastern US and certain areas of Cuba.
Noted for its long woodpecker, the species is believed to be down to a meagre number, and sightings-while reported- have never fully be verified by experts. In 2008, a reward of $50,000 was even offered by the Nature Conservancy to a person who could lead a project biologist to a living ivory-billed woodpecker.
