See Nolet and Rosell (1998) and Véron (1992 a ). Conservation: U. S. ESA – Endangered as C. fiber birulai ; IUCN – Critically Endangered as C. f. tuvinicus, Vulnerable as C. f. birulai and C. f. pohlei ; otherwise Near Threatened. Discussion: Reviewed by Heidecke (1986) , who recognized eight subspecies, and Véron (1992 b ), who recognized six; neither supported Lavrov (1983) in treating C. albicus as a separate species. Subspecific boundaries and resultant synonymies are unclear and further obscured by historical translocations and reintroductions.
