Silver-haired Bat
Lasionycteris noctivagans
Silver-haired bats are mostly black with silver-tipped hairs. They are long-distance migrants, most appear to leave the province during the winter to find warmer climates. Where silver-haired bats from Alberta spend the winter is largely unknown. However, this species has been confirmed to hibernate in southern British Columbia, where they occupy locations such as caves, mines, trees, gaps among tree roots, and wood and rock piles. There is growing evidence that male silver-haired bats in southern BC are year-round residents, whereas many of the females are moving in from other locations (possibly including Alberta). They often roost in tree cavities or in bark crevices on tree trunks, especially during migration. Their unique coloration makes them blend in with their roosting environment.

Look for silver-haired bats in cottonwood forests near the river and in your own backyard!
The City Nature Challenge is a global citizen science bio-blitz held annually. Last year, over 66,394 people from cities around the world documented urban biodiversity on the first weekend of May. Together, they submitted 2.4 million observations for more than 65,682+ species, including more than 3,940+ rare/endangered/threatened species. In Lethbridge, we had 16 observers submit 844 observations of 278 species. Can you help us top this in 2025?
