Much effort, little prey: Poor foraging success drives bats away from cities

While some wildlife species thrive well in cities, it's harder for large, insectivorous bat species to find enough food. To get their fill, city-dwelling common noctules (Nyctalus noctula) have to hunt longer than their rural counterparts and yet they catch fewer insects. While rural bats hunt together, their urban counterparts regularly forage alone. These findings, published in the journal Global Change Biology, are the results of a new investigation led by PD Dr. Christian Voigt and Dr. Laura Stidsholt from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW).
