The opportunity to see fascinating species thriving in their natural environments draws many of us to national parks, waterways and wildlife refuges every year. Almost as alluring is the appeal of getting the perfect picture that captures an animal’s beauty, ingenuity or charisma. But our Instagram aspirations must not be achieved at animals’ expense.

Experts agree that the best way to protect and respect wildlife is to put our binoculars and zoom lenses to good use by giving these animals plenty of room to roam. We’re visiting their home, after all — and we must respect them and their space. Most species of wildlife have a healthy fear of humans and will flee, hide or stop engaging in natural behavior if they feel stressed or threatened.

Get too close and you’ll not only ruin the photo op but also jeopardize their safety and well-being. Staying far away (and, ideally, out of sight) is more likely to result in an exciting glimpse into how these animals communicate, navigate, work, play, show affection and more. It’s also required by law.

The National Park Service reminds visitors, “It’s illegal to feed, touch, tease, frighten or intentionally disturb wildlife.” The agency recommends that wildlife watchers stay at least 25 yards away from the animals. Some parks require at least a 50-yard buffer.

And that number increases to 100 yards for larger predators, such as bears and wolves. Attempting to interact with wild species hinders them from eating and drinking.
