No pics, but I frequently see gophers eating their buddies that I just shot.
Last year a good friend of mine went into the Wilmore Wilderness here in northern Alberta. I usually go too,but couldn't make it that time. He went up to a trappers cabin that has a nice porch you can use to to hide form the rain. He said as he got closer, he heard a racket out behind t he cabin,thought maybe someone was chopping wood or something. He kinda snuck up and peeked around the corner. There is a good little clearing behind the cabin,and in the middle of it was a yellow plastic bucket. Also,there was a nice orderly line of elk. The first elk in line would charge into the clearing and trample the bucket,making the noise he's heard. He said that as soon as it had trampled the bucket,it would run to the back of the line and the next one would take it's turn.
I'd of loved to see that, I've never heard of elk behaving like that.
