You will have to take my word for it that there is a little red squirrel in that dark patch foraging. You will notice that above the patch is a bird feeder and therefore that the patch is made uip of a season's worth of sunflower seed shells that keeps growing as the snow melts.
Last year after the thaw there was an enormous amount of grass and unwanted growth beneath the feeder from all of the dropped birdseed. Subsequently I chose to go with only sunflower seeds this winter because I will not care if sunflowers choose to take root in my garden, yes, even yellow sunflowers in my white Moon Garden will be allowed to stay!
Not that I expect to see many, the sunflowers appear to be an absolute smash hit with all the local critters.
