Twilight Bat Walk with Sarah Perrin

Join Biologist Sarah Perrin and Bear Yuba Land Trust for this special sunset outing at Black Swan Preserve. Perrin, a permitted bat netter and natural resources specialist with Bureau of Reclamation, will share with us her knowledge and passion for this often overlooked flying mammal.

“I think it’s important to bring more awareness to bats. Once people see them up close, they realize bats aren’t scary,” said Sarah.

Using acoustic bat detectors and mist nets, Perrin will catch and identify species found near the pond, formerly a hydraulic mine site. We’ll learn common bats found in our area and the challenges impacting populations of these important members of our interconnected food web. Prepare for a night of wonder and learning.

Cost: $15 Members, $20 Not-Yet-Members, kids age 12 and under are FREE!
