I forgot to mention that these pintails are susceptible to pesticide poisoning. I am not sure why. However, a few years back, I had seen many pintails dying due to pesticides placed on the lily leaves. The villagers could collect about 10% of the dead birds and sell them to the nearest eateries/dhabas. I was told that now the poaching has come down drastically. Didn't see evidence of such pesticide poisoning this time.
