While filming Bat Hawk..... (Macheiramphus alcinus, Anthracoceros malayanus)

Always expect the unexpected. While I'm filming these Bat Hawks (Macheiramphus alcinus) 食蝠鳶 in the wild, I hear a loud "Grrrrraaa" call from a not-so-far distance. I knew the call belonged to a hornbill; what surprises me is that it is within my sighting. Immediately, I turned my camera and tried to film the hornbill instead. It is a male Black Hornbill (Anthracoceros malayanus).

At the end of the video, a second hornbill call is heard. Not long after that, a total of four Black Hornbills (Anthracoceros malayanus) 黑斑犀鳥 flew over me. Two adult Male & Female and two young male & female.
