In 2021, Berlin teams studied 166 naked mole-rats and found they recognised colony-specific vocal dialects; cross-fostered pups learned the dialect of their new colony

Naked mole-rats possess distinct vocal dialects learned from their colony members. Researchers found these animals respond more to their own colony's chirps. Cross-fostered pups adopted the dialect of their new colony within months. Colony dialect consistency decreased significantly after the queen's death. This vocal learning places naked mole-rats among a select group of mammals.
