Disregard the article (which is about attempts to regulate methane from cattle) and focus on the picture.(Article may be behind a pay wall.) It's one cow, grazing, but what's unfair about it is how dirty the cow is. I can't figure it out. Our cows would look like that only sometimes, after a long winter when they've been in the barn all the time, except on good days when they might be let out for an hour or so while we cleaned the gutters. The cows would have been lying down, and come into contact with manure from the gutters, perhaps getting their tails wet, and slapping the manure around.
The landscape seems to me to be a fall one, not spring, although the article is on California, with which I'm not familiar.
It's also odd that the cow is alone, though that's probably an artifact of picture selection--a single cow being more photogenic than a herd.
