Spreading the Wings

Spreading the Wings, originally uploaded by Yogendra174.

So.. after a not-so-good photo-walk in the morning due to clouds.. i was very restless in the afternoon, so after a good nap i went back in the late afternoon and the setting was perfect.. sunlight at an angle and most importantly behind my back.. so the birds were very well exposed.

I had to take out my shoes and walk in the mud to get near the birds.. bit risky but i think its worth it... looking at the shot!

Can someone help me put the "correct" name for this geese like bird? (is it chakrawak?)
