As AI and bioacoustics, as well as other clever new techniques, bring us ever closer to talking with animals or at least listening in on their conversations — should we prepare to update the way legal systems deal with animals?

We had already used machine intelligence to analyze the codas, recorded using bioacoustics, and determined that both the clicks and the intervals between clicks are important.

Researchers in Syracuse University's Bioacoustics and Behavioral Ecology Lab, led by Susan Parks, professor of biology, have been utilizing this technology to study the behavior of humpback whales in the North Atlantic Ocean.

"The first acoustic recordings of humpback whale song by Roger and Katy Payne in 1970 resonated with humanity profoundly, started the flourishing field of marine bioacoustics, and sparked global interest in marine conservation efforts." says Coen Elemans.

But three strandings close to his lab enabled lead author Coen Elemans, professor of bioacoustics at the University of Southern Denmark, to collect fresh vocal tracts from a recently deceased humpback, minke, and sei whale.
