Briefings

Research led by Connor Proudfoot at Jorg Massen's Vulture Cognition Lab revealed that critically endangered Rüppell's vultures produce a diverse array of complex sounds for social communication, contradicting the long-held belief that they make few simple calls. This study, published in PLOS One, suggests these vocalizations aid in social interactions and may influence captive breeding outcomes. The findings highlight the complexity of avian communication in endangered species.

Key points

• Connor Proudfoot conducted the study at Jorg Massen's Vulture Cognition Lab.
• The research focused on the critically endangered Rüppell's vulture.

Context

Vultures were previously thought to make few and simple sounds, but this study investigates their complex communication methods in detail.

Limitations

The study covers only the Rüppell's vulture, and findings may not apply to other vulture species or all social situations.
