Research suggests sentinel warning calls may be universally understood across continents

October 27, 2023

Animals often use vocalizations to warn of nearby danger to others. While this information is generally intended for members of the same species, other species can eavesdrop on the warnings to use the information for their own benefit. Sentinels are animals that have warning calls so widely understood by others that those other species will form groups with them, relying on the sentinels to provide warnings for danger.
