Black-crowned Night Heron

The black-crowned night heron (Nycticorax nycticorax 夜鷺), or black-capped night heron, is a medium-sized heron with yellow legs. Adult has black crown and black with grey and white wings and long white plumes on back of head.   I encountered the first guy standing at the edge of a fish pond in the Hong Kong Park staring motionlessly on the 20th of this month.

The other one that I encountered was at the Lake Ad Excellentiam in the Chinese University, Shatin a few days ago, where the night-Heron was standing still on a fence just above the water surface, waiting to ambush its prey.
