The Oriental Pied Hornbill is one of the ten species of hornbills found in Malaysia, and known to be an adaptable species with regard to utilising available food resources, although there is not much information about its foraging behaviour where its habitat overlap with human activities. We observed an opportunistic behaviour of a pair of Oriental Pied Hornbills preying on farmed edible bird nest swiftlets, in the state of Sabah, Malaysia as captured by closed circuit television utilised by an edible bird nest entrepreneur. A more detailed study could better assist and determine the frequency of this particular predation-prey interaction which may be a new cause of human-wildlife conflict in Malaysia and illuminating the diet diversity and adaptive ability of this hornbill species to seeking their dietary range.
