Scientists have discovered a completely new type of roar that originates african lion, indicating big cat’s Communication may be more complex than popular belief.
Researchers at the University of Exeter said this discovery could change wildlife monitoring and conservation work.
Their study additionally documented and classified an “intermediate roar”. Lionis famous roar at the top of your lungs,
Researchers were able to distinguish between two roars using artificial intelligence for the first time.
“Lion roars are not just iconic, they are unique signatures that can be used to estimate population sizes and monitor individual animals,” said biologist Jonathan Grocott of the University of Exeter, who specializes in using modern technology to conserve large carnivores.
“Until now, identification of these roars has depended on expert judgment, which introduces potential human bias,” said Dr. Grocott, author of the study published in the journal Nature. Ecology and Evolution, couple,

The African lion is classified as vulnerable to extinction on the Red List of the International Union for Conservation of Nature.
There are estimated to be 20,000 to 25,000 wild lions in Africa, a figure that has halved in the past 25 years.
“Our new approach is using aye “It promises more accurate and less subjective monitoring, which is important for conservationists working to protect declining lion populations,” Dr Grocott said.
The latest study establishes that the lion’s roar includes a full-throated roar as well as a newly named “intermediate roar”, challenging the long-held belief that they produce the same sound.
This discovery aligns with the discovery of multiple vocalizations in other large carnivores such as the spotted hyena, highlighting the growing potential of using AI for research on animal acoustics.
The researchers said the new method of using AI to detect and classify lion calls could make population estimates more accessible and reliable than traditional methods such as camera traps or spoor surveys.
“We believe that a paradigm shift in wildlife monitoring and a massive change in the use of passive acoustic techniques is needed,” said Dr. Grocott.
“As bioacoustics improve, they will be critical to the effective conservation of lions and other threatened species.”
