Much of the Mascarenes' native fauna has become endangered or extinct since the human settlement of the islands in the 17th century. Settlers cleared most of the forests for agriculture and grazing, and introduced many exotic species, including pigs, rats, cats, monkeys, and mongooses.

Ƙarin nau'ikan tsuntsaye goma sha uku sun ƙare, gami da Réunion flyless ibis, parrot mai faɗin baki, jan dogo, Rodrigues rail, da Rodrigues solitaire.

Contemporary sources state that the dodo used gizzard stones and could swallow Ocotea fruits. Seed distribution of at least some Ocotea species is performed by frugivorous birds and there exist a few reports of "solitaires" from the Mascarenes without mention of which island these came from, and the term was also used for other species with "solitary" habits, such as the Réunion blue swamphen and the Réunion sacred ibis. At one point it was even believed that Réunion was the home of not only a white dodo, but also a white solitaire. In 1786, sub-fossil bones were discovered in a cave which confirmed Leguat's descriptions, but at this time no living residents of Rodrigues remembered having seen living birds. The star constellation Turdus Solitarius was named after this bird.
