We were using my lake to shoot a spec video segment for a local fishing program. It was a gorgeous fall day, colors in the trees and sky were beautiful. The first part of the shoot went fine, the big bass were cooperating. Got some great shots of the fishing team bringing in some nice 3-5 lb large mouths. The goats would wander over to see what was going on, then lose interest and leave after discovering there were no cookies involved, a serious oversight by craft services in their mind. We moved over to the north side of the lake and after a few minutes I kept hearing this low frequency rumble in the headphones. I'd turn around to see what it was and the noise would stop. The goats had followed us over but they seemed to be grazing as normal. I'd go back to shooting and pretty soon the grinding, rumbling noise would start up again. After four blown takes I told the fishing team to move around to the other side for some long shots and panned the camera around to see if I could find the source of the noise. Facing away but watching the monitor I found out what it was. The goats were crunching acorns. With their big body cavities the crunching noise was magnified at the low end of the scale, almost like a rumble. We all had a good laugh over that. I've seen them eat leaves, grass, weeds, vines, even pine needles but I had no idea they would eat acorns. But once I started paying attention I would see them doing it. The squirrels sit up in the tree and fuss at them for hoovering all their stash. Their jaws must be more powerful than I gave them credit for. They are definitely seeking them out. They have plenty of forage and I stock hay for them besides the pasture. I started worrying about oak poisoning, but they're all fat and happy. Anyone ever seen an actual case of oak poisoning in their animals? Besides the acorns they'll vacuum up the oak leaves like candy. It can't be too bad for them.
