They simply belong to the summer nights: Bats, the mysterious hunters with their unique ability to orientate themselves, their artful flight and their technical skill in catching prey. Since we have been able to unlock many of their secrets with high-speed cameras and bat detectors, and thus know more about their lives, they have been at the top of the list when it comes to observing nocturnal animals. But bats need our help. How can we preserve or provide them with roosts, how can we protect them and their ancestral territories? This book leaves no question unanswered about the life of these unique nocturnal animals. Recommended by NABU.
