Mark of the Oriental Pied Hornbill on the papaya fruit

Tan Teo Seng recently sent me a few papaya (Carica papays) fruits from his farm in Kota Tinggi in Johor, Malaysia. He observed the Oriental Pied Hornbill (Anthracoceros albirostris) at various times trying to eat them. However, as the fruits were just beginning to ripen and not soft enough for the bill to penetrate, the bird simply left its mark on the skin.

The image above shows a characteristic, incomplete “teardrop” mark on the fruit. The bird must have returned days later but would find the fruit gone, sent to Singapore for consumption.
