Bats probe the aerosphere during landscape-guided altitudinal flights
ABSTRACT – As the only mammals capable of powered flight, bats make efficient use of the aerosphere. Yet, our understanding of how bats use the three-dimensional air column is sketchy. By attaching miniaturised Global Positioning System tags to cave bats near a mountain ridge in Thailand, we show that these bats perform undulating ascending and descending flights in quick succession. Bats repeatedly used mountain slopes to ascend to altitudes of more than 550 m above the ground. We infer that mountain . . . Complete article »

Habitat use of bats in relation to wind turbines revealed by GPS tracking
Abstract: Worldwide, many countries aim at countering global climate change by promoting renewable energy. Yet, recent studies highlight that so-called green energy, such as wind energy, may come at environmental costs, for example when wind turbines kill birds and bats. Using miniaturized GPS loggers, we studied how an open-space foraging bat with high collision risk with wind turbines, the common noctule Nyctalus noctula (Schreber, 1774), interacts with wind turbines. We compared actual flight trajectories to correlated random walks to identify . . . Complete article »
