Over in the neighbouring Malaysian state of Johor, Tan Teo Seng reports that he regularly sees the Oriental Pied Hornbills (Anthracoceros albirostris) eating the soursop fruits (Annona muricata).
Teo Seng has a number of these trees in his fruit farm in Kota Tinggi and seldom gets to harvest the fruits. The hornbills always beat him to them. However, he manages to beat the hornbills to the papaya (Carica papaya). The birds always visit the about-to-ripe fruits and make marks on the skin but when the papaya ripens, Teo Seng always beat them to it.
