The supposed "white dodo" (or "solitaire") of Réunion is now considered an erroneous conjecture based on contemporary reports of the Réunion ibis and 17th-century paintings of white, dodo-like birds by Pieter Withoosand Pieter Holsteyn that surfaced in the 19th century. The confusion began when Willem Ysbrandtszoon Bontekoe, who visited Réunion around 1619, mentioned fat, flightless birds that he referred to as "Dod-eersen" in his journal, though without mentioning their colouration. When the journal was published in 1646, it was accompanied by an engraving of a dodo from Savery's "Crocker Art Gallery sketch".[127] A white, stocky, and flightless bird was first mentioned as part of the Réunion fauna by Chief Officer J. Tatton in 1625. Sporadic mentions were subsequently made by Sieur Dubois and other contemporary writers.[128]
Baron Edmond de Sélys Longchamps coined the name Raphus solitarius for these birds in 1848, as he believed the accounts referred to a species of dodo. When 17th-century paintings of white dodos were discovered by 19th-century naturalists, it was assumed they depicted these birds. Oudemans suggested that the discrepancy between the paintings and the old descriptions was that the paintings showed females, and that the species was therefore sexually dimorphic.[129]Some authors also believed the birds described were of a species similar to the Rodrigues solitaire, as it was referred to by the same name, or even that there were white species of both dodo and solitaire on the island.[130]
Pieter Holsteyn's painting of a white dodo, mid-1600s
The Pieter Withoos painting, which was discovered first, appears to be based on an earlier painting by Pieter Holsteyn, three versions of which are known to have existed. According to Hume, Cheke, and Valledor de Lozoya, it appears that all depictions of white dodos were based on Roelant Savery's painting Landscape with Orpheus and the animals, or on copies of it. The painting has generally been dated to 1611, though a post-1614, or even post-1626, date has also been proposed. The painting shows a whitish specimen and was apparently based on a stuffed specimen then in Prague; awalghvogel described as having a "dirty off-white colouring" was mentioned in an inventory of specimens in the Prague collection of the Holy Roman Emperor Rudolf II, to whom Savery was contracted at the time (1607–1611). Savery's several later images all show greyish birds, possibly because he had by then seen another specimen. Cheke and Hume believe the painted specimen was white, owing to albinism.[113][49] Valledor de Lozoya has instead suggested that the light plumage was a juvenile trait, a result of bleaching of old taxidermy specimens, or simply artistic license.[131]
In 1987, scientists described fossils of a recently extinct species of ibis from Réunion with a relatively short beak, Borbonibis latipes, before a connection to the solitaire reports had been made.[132] Cheke suggested to one of the authors, Francois Moutou, that the fossils may have been of the Réunion solitaire, and this suggestion was published in 1995. The ibis was reassigned to the genusThreskiornis, now combined with the specific epithet solitarius from the binomial R. solitarius.[133] Birds of this genus are also white and black with slender beaks, fitting the old descriptions of the Réunion solitaire. No fossil remains of dodo-like birds have ever been found on the island.
