IN December, wolf 832F ventured out of her territory in Yellowstone’s Lamar Valley. As soon as she left the park, she lost its protections, and the wolf, a 6-year-old alpha female, was shot and killed by a hunter.

It’s rare for the death of an animal to make the news, but wolf 832F was a bona fide celebrity — one of Yellowstone’s most visible and popular wolves — and her death led to a public outpouring of grief. Making her death even more tragic was the fact that she had been wearing an expensive GPS tracking collar, which allowed scientists to follow her every move and gain crucial insight into the lives of gray wolves.

In recent years, there has been much pontificating about how modern communications technologies are changing the way that we relate to other people. Less discussed is the way these advances are reshaping our relationships with other species. By using satellite and cellular tags to track free-ranging animals, biologists are providing us with intimate access to the daily lives of other species, drawing us closer to the world’s wild things and making us more invested in their welfare.

Over the past several decades, the use of wildlife tags has proliferated as the devices have become smaller and more powerful. Today’s tags are capable of collecting months’ or years’ worth of data on an animal’s location at a given moment, and can be used to track everything from tiny tropical orchid bees to blubbery, deep-diving elephant seals. The devices provide crucial information about populations — helping scientists uncover the migratory pathways of Arctic terns or the ocean currents that loggerhead sea turtles like to surf — as well as individuals. Is this particular predator a pack leader or a lone wolf? A dedicated hunter or a mooch? How much time does it spend with its pups? Who are its associates, rivals and mates?
