Researchers report evidence that Madagascar’s singing lemurs may enhance how far their songs carry by using a vocal adjustment similar to a technique used by human opera singers.

The study compares the physical changes in the mouth and throat during high-pitched vocalizations with what is known about how singers produce “high notes” that travel farther. The findings suggest singing lemurs may shift the shape of their vocal tract—potentially improving sound projection while calling from the forest canopy.

Both outlets describe the work as new biological research on how the animals produce and project their distinctive calls. The main difference is presentation: one outlet frames the comparison explicitly around opera-style reach for high notes, while the other primarily relays the same scientific conclusion without additional detail in the provided excerpt. Neither outlet disputes the core claim that lemurs may be using a comparable anatomical mechanism to make their songs carry.
