Hornbill has an important role in forest regeneration, but the limited variety andamount of food available to birds will eventually threaten the population of hornbills.Identification of feed plant and hornbil species diversity was conducted at the HarapanRainforest from March to April 2011. Hornbills plant feed samples were taken right after thebirds were eating. The results showed there are nine plant species of hornbills feed found in theHarapan Rainforest: Santiria apiculata, Elaeocarpus sphaericus, Sapium baccatum, Lithocarpusreinwardtii, Disoxylum excelsum, Ficus curtipes, Knema globularia, Knema furfuracea, andSantiria oblongifolia. Of these nine species, Ficus curtipes is the most preferred feed by thehornbills.
