Sulawesi
Wrinkled Hornbill (Aceros cassidix)
|
GENERAL INFORMATION
This subspecies A. c. cassidix is restricted to the Indonesian islands of Sulawesi, Lembeh, and Togian, where it occurs in evergreen forests up to 1800m. In South Sulawesi, this species has been declared the state bird (Poonswad 1993). Kinnaird and O'Brien (1996) have documented high densities around fruiting trees but caution that the species may be declining as forest habitat is also declining. It is difficult to accurately census a nomadic species that congregates around fruiting trees; counts based on temporary, mobile aggregations may result in an exaggerated estimate of the population's true numbers. A second subspecies, A. c. brevirostris occurs on the islands of Buton and Muna. Kemp (1995) suggests that this form represents the southern end of a cline through Sulawesi.
The first documented captive breeding
in this region occurred at Audubon Park and Zoological Garden in 1991.
Michi (1993) wrote about breeding this species at Walsrode Vogelpark at
Mallorca, Spain. |
