Wildlife biologists made a surprising discovery of endangered Indiana bats in Vermont and want to understand why the summer colony formed:
Vermont Fish and Wildlife's Emily Paribello and Alyssa Bennett stand in front of a tall dead tree where Indiana bats are roosting.
The Indiana bat has been protected for decades, but it’s even more vulnerable now. The fungus-caused white nose syndrome, first discovered on bats in a cave near Albany in 2006, has devastated bat populations. Some species have experienced 90% declines.“But what we’ve seen with Indiana bats that initially declined by about 35% [because of white nose syndrome], is that over time they have continued to decline in many parts of their range," she said.
Bennett brought along three transmitters — an aspirational number. But when the mist nets were set up and twilight descended, four female Indiana bats flew right into the nets. In case you have no idea if that’s a lot or a little: it’s a lot. Post-white nose syndrome, most colony counts around the country have tallied about 50 to 80 Indiana bats. In this colony, Bennett estimates there are a total of 500, most of them with babies.
And the radio transmitters they affix to the bats’ backs need to be less than 5% of their body weight. On this day, summer intern Emily Paribello has a hunch about where one of them might be tucked up. Her money is on a big old tree on some Fish and Wildlife easement land a few miles away.
