In June of 2006, an anonymous reward of $10,000 was made public to anyone who could offer legitimate information and proof of the existence of a specific bird either by its nest, roost, or feeding site. In December of 2008, a larger $50,000 reward was offered to anyone who could lead a biologist to a living specimen of this same bird. What exact bird were these rewards offered in exchange for proof of? One of the most impressive and largest woodpeckers known to exist in modern times, the Ivory Billed Woodpecker.
