Sunda Wrinkled Hornbill (Aceros corrugatus)
The other common name in use is Wrinkled hornbill.
Range, Habitat, and Status
This species occurs in southern Thailand, Peninsular Malaysia,the Indonesian islands of Sumatra, Rupat, Payong, Batu; and throughout Borneo. It inhabits lowland primary evergreen forest. Generally uncommon, but fairly common in North Sarawak, Brunei, and south Sumatra; rare in Peninsular Malaysia; endangered in Thailand. As with other hornbills, they are nomadic, covering large areas between foraging areas and roosts. This makes surveys difficult. Collar et. al. (1994) lists this species as “near-threatened”.
This species was first bred in captivity at Audubon Park in 1988 (Sigler and Myers 1992). Presently, there are successful breeding pairs at Honolulu Zoo, San Diego Wild Animal Park, San Diego Zoo, and Ft. Worth Zoo (Lindholm 1999). Private breeders, Mike Gaborek, Jerry Jennings, and Tim Kitchens have each fledged single birds in 1999 or 2000.
In Europe, there are several pairs that have bred recently. They are located at: Walsrode at Mallorca, Chester Zoo, Birdpark Avifauna (The Netherlands), La Palmyre (France), Palmitos Park, and Paultons Park (Low 1999; Summers 1998; Wilkinson et al 1996).
Jens Lilleor at the Aalborg Zoo in Denmark is the European studbook keeper for this species (2nd edition: August 2000).
Aceros corrugatus has the greatest number of living species listed in the North American regional studbook (33.31.1 in 24 institutions;) as of 31 December 2000. To maintain genetic variation in a self-sustaining captive population, this species will be closely managed with a Population Management Plan (PMP).
