If you read the comments after the story, people who are around cows seem to agree that the N-S study was bull. That agrees with my experience around here, that things like wind direction, sun position, and land slope are the factors, and on a calm day the cows are randomly scattered (unless heading for the barn).
who has had 3 cows and about 30 sheep (not all at once) on my Bar BQ ranch.
