It has been noticed that these Black-crowned and rufous Night-herons were flocked together and colonised one place for roosting. When they abandon or move to another place, they do the same. I take an advantage and go to their roosting place for their pictures and these birds would not be easy to find too once they move to another place. Happy birding.
