Last Saturday, when M. and I parked at Norris Geyser Basin's lot, I saw a raven burying what looked like a piece of cracker under some gravel. Later we found the source: this pillaged Jeep Wrangler.
The owner and his pal came along while I was shooting pictures. They were astonished to discover that not only had the ravens ripped into some plastic bags, but they had also unzipped some luggage and gotten into it as well.
If ravens are smart enough to play dead, it is not surprising that they can open zippers.
