For a small investment, you can watch from afar the comings and goings of Yellowstone Park’s wildlife. This is a worthwhile website with reports by real naturalists and experienced wolf-watchers.
Besides the almost daily reports, you can also find pictures of the animals and birds the naturalists are seeing. Spring is a great season to be watching all this! And it’s a time when—for personal reasons—very few of us are likely to be there. In fact, these weeks are also not the best time to visit most of the park, because not all roads and facilities are open yet, and because the weather is usually quite iffy until mid June or so.
