WNS Detected in Mississippi
The Mississippi Department of Wildlife, Fisheries and Parks has announced the confirmation of white-nose syndrome in Mississippi for the first time. A tri-colored bat with visible fungal growth was confirmed positive for the disease by USGS National Wildlife Health Center. While WNS has been confirmed in multiple manmade structures used as hibernacula (tunnels, bunkers, etc.), this is the first confirmation of disease in a roadway culvert in the southeast. In addition to being the first confirmation of WNS in MS, this observation is notable because Pd has been routinely found in these culverts without confirmation of disease in previous years.
WNS Detected in Minnetonka Cave
Idaho Fish and Game and the US Forest Service have both announced the detection of Pd on six bats at Minnetonka Cave, a show cave in southeastern Idaho. The six affected bats were of three different species: little brown, long-legged, and Yuma myotis - all species that have previously been confirmed with white-nose syndrome. There has been no evidence of WNS at the site to date. This is the first confirmation of Pd in Idaho. This detection is now displayed on the white-nose syndrome spread map along with other Pd and WNS detections.

MYLU Declines in Azure Cave, Montana
Montana Fish Wildlife and Parks, Montana Natural Heritage Program and the Bureau of Land Management recently shared the results of their winter survey of Azure Cave. Previously, this hibernaculum housed the largest winter colony of little brown bats in the state and across much of the west. They documented a decline of 98% in the winter colony. This year marks the third winter since Pd was detected at the site.
Wanted: TABR/ANPA Roost Locations
NABat is seeking roost locations for Mexican free-tailed and pallid bats in support of an upcoming project. Roost locations will aid and validate a predictive modeling effort. We're offering multiple data sharing agreement options to ensure the security of sensitive roost sites. If you have concerns about sharing your data, we would like to discuss options with you that address your concerns. To learn more, share data, or discuss data sharing security options, please reach out to NABat's technical outreach team.
CoP Calls on Hiatus
We are taking a break from our regular monthly calls while folks are in the midst of busy summer field seasons. Keep an eye out on the events calendar for future meetings. You can also contact Bethany Straw to be added to the distribution list and receive meeting invitations directly in your inbox.
