“First bat!” The time is 9:42 pm and the sky is just starting to turn from blue to grey as dusk falls over the ranch. A silent, small dark pointy shadow zooms out of the wooden box nearby and flits overhead briefly before disappearing. This sparks a flurry of excitement among the little group of ‘bat counters’ gathered a few metres from the box, which is mounted on the wall of an old wood barn. We scramble to record the time of ‘first bat’, and click our counters, wondering whether the next bat will come in minutes or seconds.
Over the course of the next hour or so, we click away as these tiny ephemeral creatures zip out of their daytime roost box, sometimes singularly, sometimes in clusters like an explosion of shadowy fireworks. Mostly they are seen for just a second before disappearing into the night, but sometimes they whizz around our heads, presumably munching on the many mosquitoes that have been attracted by our presence. Thank you bats; enjoy the feast!
The BC Community Bat program coordinates citizen science bat counts around the province during the brief breeding season from June to early August. In Invermere we are blessed with a wonderfully enthusiastic ambassador of the program, Georgie West, who can keep you entertained for hours with fascinating facts and stories about bats (did you know the females mate with males in fall, but then choose whether to fertilize their eggs only in spring once they have checked out their roost box and know it’s secure!?).
Surprisingly little is known about our bats, like exactly where they go in winter, but annual maternity roost monitoring helps biologists to track how the bat populations are doing year on year, and also, very importantly, monitor for white-nose syndrome, which fortunately hasn’t yet spread to our local populations.
To learn more about these cute creatures, white-nose syndrome, bat boxes, or how to safely remove bats if you need to, visit bcbats.ca. The summer bat count is now over, but if you’d like to lead one next year, or have bats on your property, you can contact Georgie on bmirth@shaw.ca. |
