It's hot, humid and thunder rumbles threateningly around nearby hills. A river of sweat runs down my back and between plucking blackberry thorns out of my socks I swat swarms of blood-thirsty mosquitos.
To say conditions are far from comfortable would be an understatement. But I wouldn't want to be anywhere else, for I'm about to witness one of our region's most captivating wildlife spectacles - the nightly fly-out of the aptly named eastern bentwing bats (Miniopterus schreibersii) from a cave squirrelled away in the hills of Wee Jasper.
