The edge of the band on the horse lying down is an extension of the line between the grassy area and dark area to the right of the horse.
The edge of the band on the standing horse is an extension of the line between the dark area and the brightly lit area -- ignoring some dark trees -- to the right of the horse.
So I'd guess the bands are produced in-camera due to some electronic process that produces the final chip state.

The horses have dark bands occupying lower halves of their bodies. What do you these are?
I was thinking of excessive shutter speed beyond flash synchronization, but the apparent result is uneven. Perhaps there is a building behind the photographer, and behind the building a bright light, different from the intensity of the on-camera flash.
