was a beautiful evening when it was virtually impossible to seperate the horizon from the sky the low tide had begun and i was trying to stalk a grey heron to get it with its reflection, while shooting it i heard a diffrent kind of call which i had never heard before, an adult crab plover and a juvenile were flying by, i had the Nikon D40 with the Sigma 170-500 dg lens on it, (Darn!!! - the autofocus would not work as the D40 doesnot have a motor and same goes with the sigma 170-500) somehow luck was on my side and i managed to focus on these beautiful birds as they came close.
