I think it was known that echolocation is used for 'collision detection' and finding food, but not necessarily that bats could navigate long distances using echolocation alone. The editor's summary of the article is more clear imo: > Insectivorous bats are well known to use echolocation to catch prey and navigate around obstacles. It has also been shown that more visually guided fruit bats have spatial cognitive maps of their environment. Goldshtein et al. placed minuscule GPS trackers on tiny pipistrelle bats in conjunction with temporary blocks of vision and olfaction. The authors found that the bats could still navigate across kilometer scales using only echolocation. Thus, echolocation may not only allow for local navigation, but might also translate into an acoustic cognitive map of the environment that the animals can use to navigate over long distances. —Sacha Vignieri https://www.science.org/doi/10.1126/science.adn6269 https://www.science.org/doi/10.1126/science.adn6269
