Oriental Pied Hornbill at Sungei Buloh Wetland Reserve

Hornbills Nesting in Urban Corridors

The Oriental Pied Hornbill was once locally extinct in Singapore. A reintroduction effort on Pulau Ubin in the late 1990s has since led to a self-sustaining population that now numbers over 100 individuals across the main island.

Sightings have been confirmed at Changi, Pasir Ris Park, Sungei Buloh and even residential areas near Bishan. Their preferred nesting cavities are large rain trees and mature Albizia trunks — trees increasingly under threat from urban development.

NParks has installed artificial nest boxes at several locations. During breeding season (January to June), pairs can be spotted carrying fruit to their sealed-up nest holes, a behaviour unique to hornbills where the female walls herself in during incubation.
