well judging from all of the carcesses on I 79 and 80 in Western PA I’d say that interstate highways are also disorienting.

This was discussed here a while back.

Most likely they aligned themselves with the wind. Rumps to the wind on cold days.

HAha, the AC power lines are degaussing them!

My great-uncle, who was a dairy farmer for 60 years, told me that cows always gave more milk when their stalls were aligned North-South.

they should lose their orientation when they graze or rest near power lines

It's not like they have anywhere they need to be.

Disorienting? Hardly. Little bastards seem to hang out there by the hundreds around my area.

Cows facing same direction ping!

Last year, a team led by Hynek Burda and Sabine Begall discovered that free-ranging cattle and deer tend to align their bodies in a north–south direction. The animals sure seemed to be responding to the geomagnetic field.

This would be like trying to navigate using only lines of longitude. You would have no idea where you were in latitude. Not a very good nav system.

Deer and cattle go north south and sheep in circles.

I guess hiring them as power company employees was a mistake.
