To the uninformed like me– almost all white-birds are Crane (கொக்கு) - or could be a Heron too !!
– photo taken not in Vedanthangal or any sanctuary – not even marsh lands of pallikaranai but from the mottaimadi @ Thiruvallikkeni a couple of years ago !
Patiently standing alone gazing the sky, occasional spotting of a bird, and by the time you ready your camera, it is gone ! or even when seen in lens, camera would not adjust to lighting and may not click … .. at times, when you get a click – it is bliss !!
