What is white-nose syndrome in bats?

Scientists count bats in the winter to make sure their populations are doing okay. They look in caves and abandoned mines where bats hibernate when it is too cold to hunt for insects to eat. About 10 years ago, during their annual winter bat counts, scientists noticed that bats in caves in New York state were dying. The bats that were still alive had a white fuzzy growth on their muzzles and wings. Scientists didn’t know what it was and named it

Now we know a lot more about white-nose syndrome, a disease that kills bats when they hibernate. I am

The white-nose syndrome disease is caused by a fungus that grows on bats’ skin when they are trying to survive winter by hibernating in cold, dark subterranean habitats like mines and caves.

The fungus that causes this disease can live on the walls of caves and mines. It grows best in cold temperatures and infects bats when their immune system, which fights infection, isn’t as active.

Bats have skin on their wings, muzzles and a membrane that connects between their tail and hind legs. The fungus eats into those skin tissues, causing lesions. The infection causes the bats to wake up from their energy-saving torpor. Bats can’t survive for long in the middle of winter without food, and they starve to death.

Bats started dying by the thousands in the winter of 2006-2007, sounding the alarm that something was seriously wrong. Some bat species are more vulnerable to the disease, like the northern long-eared bat, the little brown bat and the tri-coloured bat.

We estimate that millions of bats across North America have died as the fungus has spread. Bats need our help. In the past 10 years, many wildlife biologists have worked hard to help bats survive. There are no easy solutions, but a lot of scientific research is underway to discover how we can protect bats.
