Temperatures in Hibernation sites

This is a brown eared bat photographed by Danny Fellman on a previous hibernation survey when it was really cold

Up until last year we measure air temperature with a digital thermometer, then last year, we were helping an American researching the incidence of the white nose fungus in the UK Bats infected with WNS fluoresce under uv and he send us a uv light and an infra red thermometer so we could measure the temperature of the bricks rather than the air temperature.

We just love a new gadget and  collected the temperature of both the air and the wall this month, with interesting results

There was a mean difference of  4.1 degrees. Site18 with the greatest difference(7.1 degrees ) had no bats hibernating in it
