CITES Appendix 1
Captive breeding is ongoing in Toledo and New York Bronx Zoos. The captive populations have fluctuated as husbandry problems have been encountered and addressed (animals were initially plagued with various infections and nutritional deficiencies). Ex situ colonies were comprised of a total of 460 individuals on February 12, 2007 (CBSG 2007).
Reintroduction efforts will be seriously hampered by need to re-establish the highly specialised habitat type and the presence of high levels of pesticides in the home habitat.
