Due to ongoing habitat loss and overhunting in some areas, the Great Curassow is evaluated as Vulnerable on the IUCN Red List of Threatened Species. It is listed on Appendix III of CITES in Costa Rica, Guatemala, Colombia and Honduras. Of the smaller subspecies griscomi of Cozumel Island, only a few hundred remain. Its population seems either to have been slowly increasing since the 1980s, or to be fluctuating at a low level; it is vulnerable to hurricanes.
