In the early 1900s, conservationists warned of the impending extinction of the Ivory-billed woodpecker.

From 1937 to 1939, James Tanner, a young doctoral student at Cornell University, researched the Ivory-billed woodpeckers of the Singer Tract.

Prior to the 2004 discovery of the Ivory-billed Woodpecker at Cache River National Wildlife Refuge in Arkansas, this was the last authenticated sighting of the bird in the United States.

The photos below were taken by Dr. James Tanner, and were given to the Service upon the establishment of Tensas National Wildlife Refuge in 1980 on lands of the former Singer Tract. Prior to the 2004 sightings, the Singer Tract is the location of the last confirmed Ivory-billed Woodpecker in 1944. (Click on thumbnail for a larger image)
