- The Cuban form of the Ivory-billed Woodpecker was considered a separate species at one time. It closely resembled the bird from the United States, but it had a slightly smaller bill and the white neck stripes extended farther onto the face. It suffered the same fate as the mainland form, disappearing as the mature forests were destroyed. The last confirmed sighting was made in 1986. Some may still persist in southeastern Cuba, but it may be extinct.
- The Ivory-billed Woodpecker is very similar to the larger and very closely related Imperial Woodpecker of Mexico. The Imperial Woodpecker, the largest woodpecker in the world, lacked the white neck stripes and had a longer, thinner crest. It was a bird of mature pine forests, and also is likely extinct.
- Bills of the Ivory-billed Woodpecker were used as decorations by native Americans and a thriving trade in them existed across much of North America. The presence of Ivory-billed Woodpecker skulls in excavations of archaeological sites outside of the known range of the woodpecker show the extent of the trade and not an ancient range for the species.
- The Cornell Lab of Ornithology was involved in an attempt to relocate the Ivory-billed Woodpecker in Louisiana in 2002. Go here for details of that search and more information on Ivory-billed Woodpeckers. No ivory-bills were found, and a potential double-knock was determined to be gunshots. Read a report of the expedition published in BirdScope The story of the successful hunt for the species in Arkansas in 2004 and 2005 can be found here.

Ivory-billed Woodpecker may be extinct. Partners in Flight does not list a population, but rates the species as a 20 out of 20 on the Continental Concern Score. Ivory-billed Woodpecker is listed on the 2014 State of the Birds Watch List, which lists bird species that are at risk of becoming threatened or endangered without conservation action. It is a Tri-National Concern species and a U.S.-Canada Stewardship species. Ivory-billed Woodpecker is also listed as Critically Endangered on the IUCN Red List, and federally Endangered by the U.S. Fish and Wildlife Service. 100% of birds occur in the U.S. Destruction of the woodpecker's forest habitat caused populations to decline, and by the 1880s the species was rare. Forest destruction accelerated for the war efforts of World Wars I and II probably caused the final loss of the species in the United States. Although the species was thought to be extinct, it was rediscovered in Arkansas in 2004, though there have been no confirmed sightings since 2005.
