Air Force wants acoustic sensors to help save the squirrels

Tracking system will help Edwards AFB comply with Endangered Species Act

You might not think squirrels are a big concern of the Air Force. But the military branch is required to comply with the Endangered Species Act while testing and evaluating new military aircraft and systems, activities that can include bombing the heck out the landscape. And that’s where the squirrels come in.

Unsurprisingly, military strikes are not conducive to the well-being of the threatened Mohave ground squirrel, which makes its home in Edwards Air Force Base in California’s Mojave Desert. Finding and avoiding the critters is a time- and labor-intensive task, and expensive to boot.

To address the issue, as well as limit its destruction of other sensitive species, the Air Force is seeking acoustic sensor technology to locate, identify and track the squirrels, and develop an activity map with frequency and location information that researchers can use for study.  

Specifically, the Air Force is seeking ruggedized, field-portable, acoustic fingerprinting technology with a location accuracy of within two meters. The unit must be able to withstand temperatures ranging from 0 to 120 degrees Fahrenheit and 50-mph wind gusts in the desert. Plus it needs to be able to record at least two weeks’ worth of data.

Today, acoustic fingerprinting is mainly used for birds and animals such as whales and dolphins. However, most animals have at least some unique sounds for activities such as danger signals and mating calls.

The nocturnal Mohave squirrels, which spend much of their time underground or flying, are not so easy to see but are “tremendously talkative animals, which should make them easy to track with sound, reported Popular Science.

More than 300 endangered plant and animal species live on the base, reported Wired magazine.

So, they are a "flying" ground squirrel? That would make them a double whammy species - you can kill it by bombing and by getting them caught in your jet engines. I wonder if they fly into the props in wind farms too? These squirrels are dooooomed, aren't they? Or did we copy an article that talked about some kind of bird and forgot to delete the part about flying? Oh.. I found an article that may explain it.. They "fly" when captured by a hawk or an eagle which prey on them; which doesn't seem as glamourous as this article would have it sound. Or perhaps they frequently stow away on board Air Force jets to get their kicks - you know how adventurous those adolescent squirrels can be... Aallviiiiinn!!!

Spotted Owls taste like chicken.

Don't DHS and our Israeli friends have some technology like that for finding ssmuggler tunnels already? Might be a place to start, at least.
