I am not a nature photogapher (maybe not just yet) - I don't know the name of these birds. I was driving when I saw them. The birds are so sensitive to movements. They flew instantly as I was tying to get out of my car to get a closer angle. So I snapped from the driver's seat. It is a common scene to see these birds in my state's padi field. At this time of the year, farmers are planting padi - plus the rainy weather - lots of water - lots of fish!!!
