The Downfall of the IBW
Prior to the 19th Century, the Ivory-Billed Woodpecker thrived in the vast forests of virgin timber throughout what is today the Southeastern U.S. (For a map of the Southeastern Forest during this time period, click here.)
- Post Civil War: After federal laws protecting forests are relaxed in the 1870s, Northern timber companies begin logging the forests of the Southeast, destroying the Ivory-Billed Woodpecker's habitat. The forests are almost completely removed in the 40 years following the war. "Magazines were advertising to museums, saying 'You'd better get your specimen soon, because this bird will be extinct any day now," says bird photographer and Ivory-Billed expert Bobby Harrison.
