The Passerine Falculia, with its recently extinguished allies Fregilupus and Necropsar of the Mascarenes; the Coraciine Brachypteracias, Atelornis and Geobiastes, are very abundant, while Heliodilus is an owl belonging to that subfamily which is otherwise represented only by the widely-spread barn owl, Strix flammea.
Dupont, curator of the Botanic station at Mahe, who visited Aldabra in 1906, says: "The specimens represented, besides being partly peculiar, mostly belong to the Mascarenes, Madagascar and Comoros species.
The reptiles (tortoises) are also nearly allied to the Mascarenes and Madagascar species which once existed.
