Media ID: ML646513143 is used for this estimate. https://macaulaylibrary.org/asset/646513143 Note: Another smaller flock of pintails stayed in the waterbody while this large flock took to skies( This flock of ducks can be seen in the same media: Behind reeds in front of trees). Which is still not accounted for in this estimate so the real number has to be much higher Photograph divided into 24 blocks . Rough count 1700 (error +/- 50)
