Bibhav,
Do you see any blown highlights? The plumage was bright, especially during the bathing sequences.

These Pelican's were getting scared even if I did a small movement. So I was hiding behind trees and a fence. I was stationary for four hours at a stretch. It was not possible to go to the water level. Also, you will get more of trees in the background if you go for a lower angle.

Cheers,
