Don’s presentation begins with a primer on bats that covers their distinguishing features and physiology including their exceptional echolocation capabilities—“seeing with sound” in complete darkness.  

In April 2020, Don was granted a research permit by the Park to assess post-fire bat population status and recovery trends, after a human-caused fire on January 18, 2020, burned many of the native California Fan Palms in the core of Borrego Palm Canyon’s First Grove. Press releases at the time suggested resident native bats, particularly Western yellow bats, were likely killed while in their palm frond day roosts.  

The second portion of the talk will portray the survey methodology, findings, and lessons learned from Don’s acoustic survey of bats in Borrego Palm Canyon. Through the use of acoustic monitoring techniques, it is possible to identify species present and quantify bat activity levels. Don will share his findings from almost two years of data captured by a professional grade ultrasonic bat recorder positioned in the heart of First Grove. 

 

Bat Night Walk: 6:00-8:30pm  

$25 for ABF Members / $35 for Nonmembers; Register in Advance 

Limited to 30 participants 

 

Participants will caravan to various locations in the Borrego Valley to view bats, listen to their sounds using Don’s acoustic monitors, and learn more about this fascinating but lesser-known animal. The exact end time will depend on bat activity and participant interest. 

 

Walking difficulty: Easy walks of 100-200 yards at three locations 

COVID Protocol: If you have a known COVID exposure or are experiencing any symptoms of illness, please do not attend the programs. We ask that participants drive their own vehicles throughout the event. Masks should be worn when standing close together as a group.
