Aditya,
I clicked one vertical before this shot. However, I didn't like it due to the cluttered branches below. Tried one vertical with this pelican and the sky and that was also not good. In the next I tried a horizontal, and it was then that this pelican started quarraling with one on a branch below. I decided to just focus on this one to get its expression. I used f8 here to get more depth of field.

Cheers,
Sabyasachi
