Is it about our (human) constant effort to stamp our presence?
Yes. Just an observation, not a judgement (good or bad) about the species (humans). Probably territorial markings in some other species is similar! Further, abstract co-existence (flag representing humans at an unusual place and birds) appeared interesting to my senses.
Even the nature in backdrop has nearly similar colour combination, but different in purpose / consequences! .. the Egret makes all this more interesting, Ganesh.
