Bats hold important ecological roles as pollinators, seed dispersers and top predators of night flying insects. Bats also have a number of fascinating adaptations, including echolocation, a form of sonar that allows insect-eating bats to detect their prey.  This sense of echolocation is so precise that studies have shown that bats are capable of avoiding wires as fine as human hairs within their flight paths!  Discover more about the biology, life history and ecological importance of bats using the resources below.

Bats in Danger

Approximately one quarter of all bat species are threatened with extinction. Bats face critical threats to their survival, including the rapid loss of habitat to human development, light pollution that interferes with hunting behavior and the rapid spread of white-nose syndrome. 

  • Read about seven species of bats in America that are critically endangered in the U.S. Fish and Wildlife Service’s brochure “Endangered Bats of America”.  Recently, two additional species have been proposed to receive protection under the Endangered Species Act.
  • Rapid land development and human encroachment into caves, old growth forests and other forms of preferred bat habitat directly threatens America’s native bat populations. Bat Conservation International outlines some of the human induced pressures effecting bats in this online brochure.
  • Urban areas that are increasingly characterized by high amounts of light pollution, which interferes with the natural hunting abilities of bats. Read more about how this problem is threatening European populations of bats.
  • White-nose syndrome (WNS) is devastating populations of bats across the northeastern states. WNS has so far resulted in a loss of over one million bats in the past four years and scientists and land managers are racing to contain its spread.
