One of the most iconic animals to photograph in Yellowstone is the bison. These large, shaggy beasts can be found grazing in the park's grasslands and meadows. They are most active in the early morning and late afternoon, so try to plan your photography sessions around these times. Be aware that bison are wild animals and can be unpredictable, so be sure to keep a safe distance.
Another animal to look out for in Yellowstone is the elk. These majestic creatures can be found in the park's forests and meadows. They are most active during the mating season, which takes place in the fall, but can still be seen in May.
Grizzly bears and wolves are also present in the park, but they are elusive and harder to photograph. It's best to research the best locations and times to spot them. Ask other photographers and park visitors about recent sightings.
When it comes to equipment, a long lens is a must for photographing wildlife in Yellowstone. A telephoto lens with a focal length of at least 300mm is ideal for capturing close-up shots of the park's animals. A tripod is also useful for keeping your camera steady while shooting in low light.
Remember that you are in a national park, please follow all rules and regulations, and respect the wildlife. Do not approach animals too closely and always give them enough space.
Overall, May is a great time to visit Yellowstone National Park and photograph its amazing wildlife. With a little planning and patience, you can come away with some truly stunning shots.
