Black-crowned Night Heron, Polonnaruwa Sri Lanka
This was photographed on a small rock island in the middle of a reservoir, dubbed 'bird island' due to the many birds that inhabit it. Some of these include ibis, egret, lapwing, and herons. Many of the ibis were breeding and there were many broods.
The black-crowned night heron, commonly abbreviated to just night heron in Eurasia, is a medium-sized heron found throughout a large part of the world, except in the coldest regions and Australasia.
