EX
Reunion Kestrel Falco duboisi

Justification
This species was endemic to the island of Réunion, but is now Extinct and has not been recorded since 1671-1672. Persecution is likely to have driven its decline.

Taxonomic note
Overlooked by Brooks (2000), this taxon was confirmed to be a valid species that became extinct after 1500 by Cowles (1987, 1994).

Distribution and population
Falco duboisi is known only from subfossil bones collected by Bertrand Kervazo in the Grottes des Premiers Français on Réunion (to France) in 1974 (Cowles 1994). The only historical record of small falcons is of the emerillons reported by Dubois in 1671-2 as distinct from pieds jaunes and papangue, both of which probably refer to Reunion Harrier Circus maillardi (Cowles 1987). The specimens are deposited in the Muséum National d'Histoire Naturelle, Paris (Cowles 1994).

Ecology
It is likely to have occurred in open habitat throughout the island.

Threats
Reasons for its extinction are unknown, but persecution and the depredations of introduced human commensals are implicated.
