White-nose syndrome detected in bats at Rocky Mountain National Park

June 27, 2025by Ranger Tom0

The presence of white-nose syndrome (WNS) has been confirmed in three bats at Rocky Mountain National Park, according to park staff. The affected bats were found in different locations within the park, with two on the west side and one on the east side. WNS is a fatal disease that affects hibernating bats and has been responsible for the death of millions of bats in North America.

White-nose syndrome is named for the white fungus that appears on the muzzle and other body parts of hibernating bats. The disease is not harmful to humans, but it can be devastating for bat populations. It causes bats to wake up more often during hibernation and use up their fat reserves, which can lead to starvation and death.

This discovery at Rocky Mountain National Park marks a significant spread of the disease, which was first identified in New York in 2006. Since then, it has spread to more than 30 states and five Canadian provinces, causing a serious decline in bat populations across North America. The detection of WNS in the park underscores the importance of ongoing research and monitoring efforts to understand and combat this disease.
