請問拍友當時是否保持低聲談話，還是高談闊論？有時繁殖雀鳥也怕人聲。
黑卷尾天生膽大，例如主動攻擊飛過麻鷹。但不代表可容忍十多個壯漢在身邊坐定定看著自己的整個生仔過程。雀鳥的保護工作還是比拍鳥重要。拍鳥者還是要自律。
How about noise generated by the photographers? Sometimes breeding birds also threatened by human noise.
Black Drongo can be very aggressive, e.g. they attack pass-by Black Kites. But it does not imply that they can accept several big guys sitting nearby and staring their whole breeding process.
Priority should always be given to protection of birds. Self-discipline is important.
