North American bats, many of whom migrate across international boundaries, face many threats:
- Habitat destruction has limited bats’ food gathering and roosting sites throughout their range;
- Human-related disturbances, including wind turbines, can lead to bat deaths; and
- Perhaps the best-known bat-killer, for now limited to bats in the United States and Canada, is white-nose syndrome, a deadly invasive fungus. Since its discovery in New York not even 10 years ago, white-nose syndrome has spread to 26 states and five Canadian provinces and killed millions of bats.
