I have sat in the open ground near a waterhole without moving and have seen the reactions of herbivores coming to drink water. Most of the times if you are absolutely still, they chances of getting noticed is less. That is the principle adopted by these birds. In Oriya, we call it Baka dhyana means meditation like a egret (dhyana means meditation).

I like the composition. The eye contact is fine. Thanks for sharing.
