Common Shelduck

Common shelduck not to so common to see every winter in Delhi . I was also not hopeful , just not thought to find this bird in or around Delhi. Last week, I found the distant birds with some unusual color of feathers. i simply took shot and returned .  On computer / screen I found these three birds were common shelduck.  I felt very sad that I could not shot it closely.   == Photo Najafgarh Drain 18th Feb 2015
