The curiously shaded area on the left has the appearance of a grazing animal
and the smaller region to the right of it, beyond the foreground grass spike,
of a small or more distant one, as well, both well--obscured by intervening grass.
Wildebeest, maybe? Does anyone concur?
The grass isn't tall enough to hide a wildebeest; it would have to be above the height of the camera (making hard to see anything). I think those are just variations in the shading of the vegetation.
