We were recently in the news!

We have almost finished our winter bat surveys and found only 12 bats so far. Some of these were visibly infected with white-nose syndrome, but not all, so maybe these bats are capable of surviving. We were hoping the bat population had bottomed out, but this is still a decrease from last year’s survey when we found 24 bats. It is quite depressing doing surveys in empty caves where we used to find hundreds of bats.

The huge snowfall in the Maritimes this past winter has made accessing some of our sites a challenge:

Even worse, I accidentally dropped 2 ibuttons into the creek which were promptly swept away and lost! We have ibuttons in all our sites and they measure temperature twice a day. We download the data during our survey visits. The temperature deep in caves can radically differ from that outside. Bats cannot hibernate in temperatures below freezing, and the temperature deep in caves in New Brunswick is generally around 5 deg C during the winter. Much warmer than the -20 or -30 deg C outside! Luckily the ibuttons I dropped were those recording temperature outside the cave, which are not as critical to the study.

So, sans 2 ibuttons and one snowshoe, we squished our way back through the rain to the car with visions of hot showers in our heads. The creek definitely got the better of us this day! But we’ll be back…
