Ivory-billed Woodpecker Fact SheetHistory of the Ivory-billed WoodpeckerApril 28, 2005 1820Naturalist John James Audubon and his apprentice Joseph Mason shoot and collect numerous ivory-billed woodpeckers along the Ohio, Arkansas and Mississippi rivers. Audubon describes the tenacity of the bird, saying, “They sometimes cling to the bark with their claws so firmly, as to remain cramped to the spot for several hours after death.” 1837Audubon travels to Texas, where he sees many ivory-bills. He writes, “I found (ivory-bills) very abundant along the finely wooded margins of that singular stream called ‘Buffalo Bayou’ in… Texas, where we procured several specimens.” 1870sLaws protecting much of the southern forests in the United States are dropped, and timber companies begin to buy and clear critical ivory-billed woodpecker habitat. 1890sSpecimens of the rare bird become increasingly popular with collectors, and populations continue their rapid decline. 1893Johannes Gundlach publishes the first of his two-volume Ornitologia Cubana, providing the first detailed description of the ivory-bill’s behavior, appearance and habitat in Cuba. 1898After the end of the Spanish-American War, the United States takes control of Cuba’s land and economy. As much of Cuba’s forests are cleared for sugar cane, the ivory-bill is restricted deeper into Cuba’s remote forests. 1907President Theodore Roosevelt, on a hunting trip to northeastern Louisiana, sees three ivory-billed woodpeckers. He notes: “Their brilliant white bills contrasted finely with the black of their general plumage. They were noisy but wary, and they seemed to me to set off the wildness of the swamp as much as any of the beasts of the chase.” Roosevelt is awestruck by the magnificent trees of the primeval forest: “In stature, in towering majesty, they are unsurpassed by any trees of our eastern forests; lordlier kings of the green-leaved world are not to be found until we reach the sequoias and redwoods of the Sierras,” he writes. 1924Arthur A. Allen, founder of the Cornell Laboratory of Ornithology, and his wife, Elsa, discover a pair of ivory-bills near the Taylor River in Florida. Even at this early date, many ornithologists had already considered the species to be extinct. Wrote Arthur Allen: “I have just enjoyed one of the greatest experiences of my life, for I have found that which they said could not be found – the ivory-billed woodpecker. Once a fairly common bird in many parts of Florida, it is supposed to have followed the Carolina Parakeet into extinction. Those who know most about Florida birds held out little hope of my ever seeing one alive, but after a month’s search I have found a pair of them and they are very much alive.” Tragically, two local taxidermists hear of Allen’s discovery and shoot both birds – legally. 1932Mason D. Spencer, an attorney and state legislator from Tallulah, Louisiana, shoots an ivory-billed woodpecker in the Singer Tract swamp forests of Madison Parish to prove to state wildlife officials that the birds still exist in the area. 1935A team from the Laboratory of Ornithology, including Arthur A. Allen, Peter Paul Kellogg, George Miksch Sutton, and James T. Tanner, locates three ivory-billed woodpecker nests in the Singer Tract. The researchers spend several days closely monitoring one of the nests and produce the first motion pictures and sound recordings ever obtained of the species. 1937Cornell ornithologist James Tanner spends a large portion of the next three years living in the Singer Tract, collecting information about the ivory-billed woodpecker. Tanner uses the data for his Cornell doctoral dissertation, which later is published by the Audubon Society. 1939Based on his research, interviews, and explorations of likely habitat across the South, James Tanner estimates that only 22 ivory-bills exist in the United States. 1941The National Audubon Society launches a campaign to preserve the Singer Tract as a refuge for ivory-billed woodpeckers. Tanner and his wife, Nancy, see several ivory-billed woodpeckers at the Singer Tract. This is the last time he visits the area until the 1980s, when the Tensas River National Wildlife Refuge officially opens. 1943National Audubon Society researcher Richard Pough (who later becomes first president of The Nature Conservancy) is sent to the Singer Tract to determine how many ivory-bills remain. Although he searches for several weeks, he finds only one lone female in a small stand of trees, surrounded by devastation from logging. 1944The National Audubon Society sends artist Don Eckelberry to the Singer Tract to document the last known ivory-bill. With Jesse Laird, who had assisted James Tanner in his earlier field work, Eckelberry observes and sketches the bird. This is the last time until 2004 that two knowledgeable observers together observe an ivory-billed woodpecker in the United States. 1948John V. Dennis and Davis H. Crompton find three ivory-billed woodpeckers in the eastern mountains of Cuba. 1957U.S. biologist George Lamb and his wife, Nancy, locate 13 ivory-bills on Cuban property owned by U.S. corporations. He makes recommendations to conserve the land. The Cuban Revolution two years later ends ties between Cuban and U.S. scientists and conservation efforts end. 1966Olga Hooks Lloyd, a Texas birdwatcher, reports seeing an ivory-bill in the Neches River swamp in the Big Thicket area of east Texas. Later in the year, John V. Dennis follows up on her sighting and reports observing a female ivory-bill along a nearby bayou, but he fails to get a photograph or a sound recording. 1968In late February, John V. Dennis records what may be the “kent” calls of an ivory-billed woodpecker, although it is too foggy for him to see the bird making the calls. Subsequent sound analyses are inconclusive, and researchers are unable to rule out the possibility that the call notes might be an example of mimicry by a blue jay. James Tanner spends two weeks searching in the area but finds no evidence of ivory-bills. Cuban biologist Orlando Garrido reports seeing the ivory-billed woodpecker. 1986Several Cuban and international scientists report brief glimpses of the ivory-billed woodpecker in Cuba, but they fail to obtain photographs or sound recordings. 1987Cuban scientists report seeing a female ivory-bill in the mountains of Cuba. It is the last certain sighting of the Cuban subspecies. 1999David Kulivan, a forestry student at Louisiana State University, reports seeing a pair of ivory-billed woodpeckers in the Pearl River region of Louisiana. The sighting leads to renewed efforts to find the bird. 2002An expedition is launched in the Pearl River region, but no birds are found. Although the search team does find large tree cavities and peeled bark on trees, suggesting the possible presence of ivory-bills in the area, there are no definite sightings. Twelve autonomous recording units (ARUs) installed by researchers from the Cornell Lab of Ornithology fail to detect any ivory-bill calls or double-knocks. 2004Gene Sparling of Hot Springs, Ark., spots an ivory-billed woodpecker while kayaking through the Cache River NWR in east Arkansas. When confirmed by a subsequent sighting days later by Bobby Harrison of Oakwood College and Tim Gallagher of the Cornell Lab of Ornithology, a search is launched, resulting in numerous eyewitness accounts as well as video evidence showing the ivory-billed woodpecker still lives.
