00:05maybe you guessed it it's a lion but what you probably don't know is that this is a type of
00:10roar that scientists have only just discovered it's called the intermediate roar it has a flatter
00:15and less varied sound than the lion's full-throated roar which is the one we will know about
00:21the intermediate roar always comes after the full-throated one but scientists aren't sure
00:26why lions need it yet the lions use their full-throated roars to communicate with their
00:30pride a powerful sound also helps them establish their territory it's thought to contain information
00:35about their age sex and other characteristics in 2023 scientists deployed 50 microphones in the
00:41national park in tanzania to record lines full-throated roars the team thought that if
00:45they could understand the roars better then they could count the lines in the landscape and that
00:49could help them improve line population estimates the scientists analyzed 3149 line recordings with
00:55artificial intelligence and that's how they discovered the intermediate roar ai was 95.4
01:01accurate when it classified lion sounds models like this could help researchers isolate full-throated
01:06roars better and that could ultimately improve line conservation they say head to life science.com
