Flight Practice

More flight shot practice today with the Olympus EM1 M3 and Zuiko 300mm. I am using the C-AF Track mode, which locks focus on a subject and tracks it. A green box around the subject indicates that it is in focus, and if focus is lost the box turns red. 
There's a low spot in the corn field across the road from us, that becomes a duck pond in the spring. Since we had good light today, I took advantage of the opportunity and pulled my car off of the road parallel to the water. Although it's just across the road, the ducks tolerate the car, whereas if I walk over, they fly.
