eLife Assessment
This important study provides insights into the role of maternal behavior in the learning and ontogeny of vocalization, finding evidence that the maternal behavior of sac-winged bats (Saccopteryx bilineata) can influence the learned territorial songs of their pups. The behavioral analyses are solid, although a more comprehensive and quantitative description of the babblings and the female displays would have strengthened the study. The work will interest biologists and neuroscientists studying vocal learning and its evolution.
