STUDBOOK: Mindanao wrinkled hornbill, Aceros leucocephalus
The first edition of the North American Regional Aceros studbook was current through 31
December 1999. Since then, 2 annual updates were distributed to participants.
A second edition will be current through 31 December 2002 and will be
printed early in 2003. In the past 3 years, the captive status of the 5 species of Aceros covered in this regional studbook remained relatively stable.� This means that births and imports approximately equaled deaths and exports.� Whether this is good or just satisfactory will be better known when the Population Management Plan (PMP) for this genus is completed.� With a PMP, we will set goals for optimum number of birds for each species. The preliminary analysis is that we should at least recommend for PMP status, Aceros corrugatus. We might not have enough available spaces to provide for a long term, genetically diverse, self-sustaining captive population for any of the remaining 4 species. The following listing show the numbers of current living birds at the end of the past three years. |

SUMMARY for 2001:
There
are only 2.1 birds in this North American regional studbook. No Population
Management Plan (PMP) is planned for this species. Breeding is encouraged
and offspring can possibly be sent to Europe. There are plans for developing
a European studbook for this species. |
