Originally reaching as far as North Carolina, Illinois, and Texas, the range of the Ivory-billed Woodpecker had shrunk considerably by 1885. Confirmed sightings in the 20th century were confined to only a handful of locations. James Tanner studied the bird from 1937 to 1939 in the Singer Tract, where artist Donald Eckelberry painted the last Ivory-bill five years later. The 2002 search was conducted farther south, in the Pearl River Wildlife Management Area and the Bogue Chitto National Wildlife Refuge.
