On a serene morning in Lamar Valley, a trotting coyote silently leaves its tracks in the fresh snow. This photo was captured on my first winter trip to Yellowstone National Park. I had finished assisting with a photography class, and I had a day on my own to explore the snowy wonderland. It was my 17th birthday, and I was lucky enough to capture my favorite animal in my favorite place. Birthdays don’t get any better than that. Coyotes have thrived despite decades of persecution in the form of numerous and extremely toxic predicides, traps, bait stations, and aerial gunning. This assault came primarily from the United States government in an attempt to protect livestock. Coyotes have many unique adaptations that helped them to endure the onslaught, such as fission-fusion that allows them to hunt as individuals, in pairs, or in a pack. I believe that coyotes are one of the greatest wildlife success stories of the 20th century because not only did they survive this attempted annihilation, but they spread geographically and colonized every major US city in the process.
