Соціальні голоси кажанів

In a study of Egyptian fruit bats (Rousettus aegyptiacus), researchers recorded 22 animals for 75 days and analyzed roughly 15,000 vocalizations. The calls were directed toward specific individuals; acoustic analysis could identify not only the caller but often the addressee, context, and behavioral response. Some calls accompanied everyday conflicts, such as competition over food or resting spots, giving rise to the headline-friendly summary that bats “argue a lot.” But the study did not translate bat “language” into human words or show that every vocalization is an address like a human name.
