"Amazing World of Bats: Nature’s Tiny Fighter Jets" Bats! Those strange, mysterious creatures we only catch glimpses of around twilight. Bats are fascinating animals with incredible skills of flight and nighttime navigation. They contribute to our environment in surprising ways including serving as master catchers of insect pests, pollinating wild fruits, and helping reforest disturbed lands. Poorly understood and frequently feared, they are under threat world-wide due to use of pesticides, loss of habitat, and being killed by humans. They need our protection as much as we need them in healthy populations. This multimedia presentation features photographs, video, audio clips, and museum specimens.
Using an ultrasonic microphone and a tablet, the presenter, Don Endicott, will demonstrate how we hear and identify their high frequency echolocation calls used to navigate and find and catch prey in complete darkness. Don is a retired civilian research engineer/executive in the field of Navy Communications and Network Technologies, He discovered a second career as a volunteer naturalist, becoming a public educator for the San Diego Natural History Museum and the San Diego Humane Society's Project Wildlife’s “Bat Team”. He contributes full spectrum bat echolocation call recordings to the San Diego Natural History Museum and Wildlife Acoustics, a bioacoustics monitoring systems company, where they have been incorporated into reference libraries for species identification.
