 Newton 's words particularly cemented the validity of this connection among contemporary peers , and several of them expanded on his views . Dutch zoologist Anthonie Cornelis Oudemans suggested that the discrepancies between the paintings and the old descriptions were due to the paintings showing a female , and that the species was therefore sexually dimorphic . Walter Rothschild claimed the yellow wings might have been due to albinism in this particular specimen , since the old descriptions described these as black . By the early 20th century , many other paintings and even physical remains were claimed to be white dodos , amid much speculation . Some believed the solitaire of the old descriptions was rather a species similar to the Rodrigues solitaire . Rothschild commissioned British artist Frederick William Frohawk to restore the Réunion solitaire as both a white dodo , based on the Withoos painting , and as a distinct bird based on Dubois ' description , for his 1907 book Extinct Birds . In 1953 , the Japanese writer Masauji Hachisuka went as far as referring to the white dodos of the paintings as Victoriornis imperialis , and the solitaire of the accounts as Ornithaptera solitarius .
