Species that use sound to ‘fake’ their body size are usually skilled vocal learners
July 8 (UPI) -- Animals that use their voice to sound bigger than they are tend to also be skilled vocal learners, according to new scientific paper, published Wednesday in the journal Biology Letters. Previously, researchers approached acoustic allometry, the relationship between voice and body size, and vocal learning as two distinct fields of study. But over time, scientists have started to see the overlap between the two areas of research.

"In particular, we wondered: For species that are vocal learners, and which can flexibly modify their vocalizations, then how do allometric principles apply?" said Garcia, an evolutionary biologist at the Un...
