We were scanning a partially flooded field for ducks, snipes and whatever other birds may have been about. There was still a lot of ice and the amount of open water was limited. A flock of Mallards approached and, much like planes at a busy airport, circled the field several times while looking for some space to land. There were many ducks already in the small area of open water. This was an opportunity to get some in flight photos.
Some other ducks in flight:
A Harlequin Duck almost hovers as it looks for an open spot in some choppy water.
A flock of Eiders flew by, but decided not to land. The duck on the right in the top photo is a mature male. The others are immature birds.
And one more, a male Northern Pintail. You can see the reason for the name.
