Just like their human relatives, new research shows that gorillas also make melodic “yummy” noises when enjoying a meal, New Scientist reports.
The new findings, published recently in the journal PLOS ONE, were gathered by German primatologist Eva Luef of the Max Planck Institute for Ornithology and her colleagues Thomas Breuer and Simone Pika. The researchers studied two groups of wild western lowland gorillas in the Republic of Congo and observed the creatures humming and singing while eating their food. Two distinct types of calls were recorded: one that sounds like the gorilla is letting out a sigh of contentment and another that sounds like it’s humming a random tune. “They don’t sing the same song over and over,” Luef told New Scientist. “It seems like they are composing their little food songs.”
