Happy Baturday! Meet the “Skylion.” 🦇 Canada’s largest bat faces steep population declines and high mortality at wind turbines. Widespread doesn’t mean safe. Hoary Bats need protection throughout their time in Alberta, beyond short periods of curtailment during peak migration.
Close-up photograph of a Hoary Bat hanging upside down, showing white-tipped brown fur, a golden-yellow collar, rounded ears with dark edges, and a partially open mouth. Text reads: “Hoary Bat, Lasiurus cinereus. Widespread across North America. But widespread doesn’t mean safe.” A yellow badge reads “COSEWIC endangered.” Photo credit: Jason Headley. WCS Canada Western Bat Program and Alberta Community Bat Program logos appear at the bottom.

Our bat probiotic project is expanding beyond BC and WA and into Alberta and the territories! Bats benefit! We’re studying how long it persists and whether it could be used in backyard bat houses.🦇 Help fund this work: donate or run a fundraiser! wcscanada.donorsupport.co/page/FUNKNPK...
Image of a Little Brown Myotis covered with fungal growth Pd that causes white-nose syndrome in hibernating bats. Overwinter mortality rates for this species are over 90%. Photo: Greg Horne from Feb 2026. Image of a bat wing stretched out in the gloved hands of a bat researcher. UV light is shining on the wing surface where speckles of orange fluoresce under the UV light. This is a sign of fungal growth (Pd) that causes white-nose syndrome. Bats emerging from hibernation will show this sign if they have been infected by Pd. Photo: Jason HeadleyImage of the team at work processing bats in early May - documenting signs of white-nose syndrome. One researcher holds a bat while another swabs the wing with a sterile swab that will be sent away for testing. Researchers wear gloves (and change them between bats) to reduce the risk of transmission of the fungus between bats. Masks are worn to protect the bats from researchers potentially giving bats any diseases. This work involves a lot of decontamination, making processing of each bat highly involved before it is eventually released back into the night. We are grateful for a huge number of volunteers who have joined us to help with this project. Photo: Jason HeadleyOur Alberta team sprays hydrated probiotic bacteria into bat houses after bats have left to hunt for the evening. The probiotic formula dries onto roosting surfaces. Returning bats crawl over the roost surfaces and pick up the beneficial bacteria on their wings which will assist in their survival in the following winter when they encounter Pd that causes white-nose syndrome.
