Lions also have a ‘hidden’ roar, new research reveals

Lions can be identified by their roar. REPRESENTATION PIC/ISTOCK

A scientific investigation has revealed that African lions produce two separate kinds of roars. Researchers documented a previously unknown "intermediary roar" that occurs along with the well-known full-throated roar.

Their study is the first to apply artificial intelligence to automatically separate lion vocalisations into distinct types. The automated system achieved a 95.4 per cent accuracy rate and reduced the influence of human interpretation, allowing for more reliable identification of individual lions.

The automated, data-driven process also streamlines passive acoustic monitoring, offering a more accessible and dependable alternative to common methods such as spoor tracking or camera traps.
