Campephilus principalis principalis Linnaeus, 1758

Ivory-billed woodpecker



Taxonomy & Nomenclature



Conservation Status


Last record: April 1944 (northeastern Louisiana)

IUCN RedList status: Critically Endangered (Possibly Extinct)


The Ivory-billed Woodpecker has received considerable media attention in the past decade as news of its supposed rediscovery spread around the world. However, no live specimens have been captured in the 60 years since the last confirmed sighting, and all purported evidence for its continued existence is unconfirmed. 6 birds were supposedly seen in 1960 (Scott, 1965:208)

Mironov, S. V., Dabert, J. and Ehrnsberger, R. (2005). A New Species of the Feather Mite Genus Pterotrogus Gaud (Analgoidea: Pteronyssidae) from the Ivory-billed Woodpecker Campephilus principalis L. (Aves: Piciformes). Annals of the Entomological Society of America 98(1): 13-17. [Abstract]



According to the Leiden Museum, more than 400 Ivory-billed woodpecker specimens are in museum collections around the world. This includes both known subspecies. Of this subspecies, 32 are in the Field Museum, Chicago (erroneously said to be the most of any museum), and 30 in the American Museum of Natural History, New York. In addition to these figures, 69 are in the MCZ's ornithological collection, Harvard University, and 1 in the Leiden Museum's collection itself. That accounts for 132 specimens. The rest are probably scattered around the world, perhaps having been exchanged as often happens with "excess" material for new material from elsewhere.


69 specimens are held in the MCZ's ornithological collection, Harvard University:
