Check out this great item that I found online.
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 or another location of your choice to locate bats using an ultrasonic bat detector. Alternatively, you may prefer to visit Waugh Street Bridge over Buffalo Bayou, to see 250,000 Mexican Free-tailed bats emerge at dusk.
For 20 people.
