Ivory-billed Woodpeckers were last confirmed in 1944 in Louisiana and in 1986 in Cuba. Possible sightings by ornithologists, birders, and others in the years since are plotted on the map and described in more detail below. Shades of green on the map show the Ivory-bill’s declining range.
1. Highway 29, Collier Co., Fla., about 1950
Observer: Ornithologist Allan Cruickshank, father of Merritt Island National Wildlife Refuge. Notable: Today Highway 29 is the western boundary of Big Cypress National Preserve.
2. Chipola River, Calhoun Co., Fla., 1950-52
Observers: Whitney Eastman, vice president of General Mills, Muriel Kelso, Davis Crompton, and John Dennis. Notable: Crompton and Dennis had found Ivory-bills in Cuba in 1948 that Dennis photographed. In the Chipola River Swamp, conservationists, land owners, and government officials established a wildlife sanctuary, but after no additional sightings were reported, sanctuary status was discontinued in 1952.
3. South of Tallahassee, Wakulla Co., Florida, July 1952
Observer: Samuel A. Grimes, discoverer (in 1953) of the first known Cattle Egret nest in North America
4. Homosassa Springs, Florida, April 1955
Observer: John K. Terres, former Audubon Magazine editor and author of The Audubon Society Encyclopedia of North American Birds. Notable: For fear of being scorned, Terres kept the sighting a secret for more than 30 years.
5. Altamaha River Basin, Georgia, 1958
Observer: Ornithologist and forest ecologist Herbert Stoddard, who devoted the final years of his life to a study of bird kills at a north Florida television tower. Notable: Stoddard reported seeing the bird from a distance of 50 yards while he was flying in a small plane.
6. Near Thomasville, Georgia, 1958
That same year, Stoddard also reported seeing a pair in beetle-killed spruce pine near Thomasville, Georgia.
7. West of Aucilla River, Jefferson Co., Florida, 1959
Observer: William Rhein
8. Neches River Swamp, Texas, 1966, 1968
Observers: Birder Olga Hooks Lloyd (April 1966), John Dennis (December 1966 and February 1968). Notable: Dennis claimed to have recorded the bird in 1968, but some questioned the recording’s authenticity. Today, acoustics experts at the Cornell Lab of Ornithology say it is an Ivory-bill recording. In 1974, Congress set aside 84,500 acres of east Texas as the Big Thicket National Preserve, partly due to the reported sightings.
9. Near Elgin Air Force Base, Florida, 1966
Observers: Birders Bedford P. Brown Jr. and Jeffrey R. Sanders. Notable: The men heard and then saw a pair of Ivory-bills scaling beetle-killed pines for 16 minutes.
10. Green Swamp area, Polk Co., Florida, 1967
Observer: Ornithologist David S. Lee, curator emeritus of birds, North Carolina State Museum of Natural Sciences. Notable: After seeing a female Ivory-bill fly across a road 25 yards in front of him, Lee, who was then a student, returned to the swamp with his professor and discovered large slabs of bark removed from trees — typical of Ivory-bill feeding activity.
11. Northwest of Lake Okeechobee, Polk Co., Florida, 1967-69
Observers: Ivory-bill hunters H. Norton Agey and George M. Heinzmann reported seeing or hearing a bird on 11 occasions between 1967 and 1969. Notable: A feather found near a tree cavity was identified as an Ivory-bill’s innermost secondary.
12. Atchafalaya Basin, Louisiana, 1971
Observer: Fielding Lewis, chairman of the Louisiana Boxing Commission. Notable: Lewis snapped two fuzzy photos of an Ivory-bill and sent the photos to Louisiana State University ornithologist George Lowery who showed them to fellow scientists at that year’s American Ornithologists’ Union meeting. The photos met with skepticism at the time, but today, prominent ornithologists accept them as legitimate. Birding Magazine published one of the photos in its December 2001 issue.

13. Noxubee River, Mississippi and Alabama, March 1973
Observer: Ornithologist Jerome A. Jackson, author of In Search of the Ivory-Billed Woodpecker and a June 2002 Birder’s World article, The Truth Is Out There.
14. Ogeechee River, 25 miles west of Savannah, Georgia, July 1973
Observers: Rev. C. Deming Gerow and his son, Jim. Notable: The Gerows, missionaries in Argentina, were bird banders and were familiar with Campephilus woodpeckers in South America.
15. Black Creek, DeSoto National Forest, Mississippi, 1978
Observers: Ornithologists Ronald Sauey, the late co-founder of the International Crane Foundation, and Charles Luthin, executive director of the Natural Resources Foundation of Wisconsin. Notable: Sauey heard a bird that “sounded every bit like the historic Ivory-bill recording of Allen and Kellogg.”
16. Pascagoula River, Mississippi, February 1982
Observer: Birder Mary Morris of Biloxi, Mississippi
17. Loxahatchee River in Jonathan Dickinson State Park, Florida, April 1985
Observer: Dennis G. Garratt. Notable: He watched the bird from 25 to 40 feet away for about 15 minutes.
18. Near Yazoo River, Mississippi, March 1987
Observers: Ivory-bill expert Jackson and then-graduate student Malcolm Hodges, currently the stewardship ecologist with the Nature Conservancy of Georgia Notable: A bird called in response to a tape the men played of an Ivory-bill call. It approached to within about 150 yards, then disappeared.
19. Ojito de Agua area, Cuba, March 1988
Observer: Jackson. Notable: He and other ornithologists were there to follow up on a confirmed sighting in the same area two years before. Ivory-bill call notes were heard on eight different days during the ’88 expedition.
20. Pearl River Swamp, Louisiana, April 1999
Observer: Turkey hunter David Kulivan. Notable: An intensive search of the swamp by ornithologists in 2002 found no evidence of Ivory-bills.
21. Cache River, Arkansas, February 2004
Observer: Gene Sparling. Notable: Later that month, Sparling led Tim Gallagher of the Cornell Lab of Ornithology and photography professor Bobby Harrison along the Cache, and Gallagher and Harrison saw an Ivory-bill. Their sighting sparked the search that confirmed the Ivory-bill’s existence.
