Echoes in the Night

In the quiet darkness of Pacific Northwest forests, bats perform a vital ecological service: chowing down. From tiny midges and biting flies that bother humans, to moths that threaten crops, to beetles that affect forest health, bats consume a remarkable diversity of insects. They also serve as an important food source for birds of prey, such as hawks and falcons. Whether predator or prey, bats help keep ecosystems in balance. Yet in recent years, these nocturnal mammals have faced a deadly threat: white-nose syndrome (WNS).
