"As he says, it’s clear that when wolves emit howls they elicit a response, but unclear is what they are saying in reply. Is it: “Hello, stranger, we’ve not heard your voice before. Who are you?” or perhaps, “This is a warning: you’re entering out territory and it’s best you move on.” Or, maybe, “Your voice sounds sexy. Maybe we ought to hook up.” In this short video, Reed discusses how three wolves from different packs were engaged in vocal courtship in Yellowstone during the 2024 winter breeding season.
Divining insights is different from scientists being able to claim they can read the minds of their subjects, Stahler notes. Regarding wolves and other animals he’s studied, like cougars, they are always sending out clues and the challenge for humans is trying to decipher their meaning.
In Mech’s forthcoming book, The Ellesmere Wolves: Behavior and Ecology in the High Arctic, he highlights how howling female wolves on Ellesmere Island use vocalizations get a male partner to come join on a hunt. “It’s a howl of persuasion,” he says. “I don’t doubt that the kind of high tech analysis coming out of Yellowstone will be able to identify distinguishable differences in howling that happen, for example, during the breeding season.” Reed showed me an example of what he thinks might be a young wolf actually trying to learn such a “sexy” howl.
Literally, the audio recordings in Yellowstone already have enabled researchers to bear witness to young wolves coming of age, finding their voice in the pack. And, in many ways, it was no different from the exuberant racket that human kids make on a playground. They’re in a phase of hyper-learning, getting prepared for life in the real world. Central to their education is knowing how to speak the language tethered inseparably from their survival.
Beyond dispute, based upon his thousands of hours of AI processing, is that if you’ve heard one wolf howl you’ve not heard them all, Reed says. Vocalizations that sound the same to our ear probably have nuanced subtleties not only in pitch and timbre but context in which they are delivered. Do wolves have dialects that vary from region to region? Are there lilts and accents? Is there a pecking order for who howls when, and what? If two pups are wrestling over an elk bone and if one sibling says the playful equivalent of “get lost” to the other, does that same bark have a very different connotation when it’s an adult pack member patrolling the boundary of the territory and intersects with a trespasser?"
Using Artificial Intelligence and bioacoustics, America's first national park stands at the forefront of global efforts to translate the sonorous communication of wolves and other large terrestrial species
