Bat expert Cullen K. Geiselman, PhD, will share her extensive knowledge of the world's bat species, their habitat, and life histories. Afterwards join her on a twilight 'bat walk' at Edith L. Moore Nature Sanctuary, Waugh Street Bridge or another location of your choice to locate bats using an ultrasonic bat detector. (For 20 people)

Get involved in the cause and install your very own bat house to provide great shelter for these marvelous mammals.
