Behind the newest hidden feature in Kaleidoscope 2.0

You may be aware that the latest version of our spectrogram analysis software has just been released.

Kaleidoscope 2.0 has been rebuilt from the ground up, and includes new classifiers as well as a new feature known as the Virtual Call Library.

But wait...what is a Virtual Call Library anyway?

Simply put, it is our brand new feature that allows you to visually understand why the software chose to identify the pass as a particular species.

White Nose film examines progress made against the deadly fungus

White Nose film examines progress made against the deadly fungus

Four years ago, Ravenswood Media released a highly informative video called The Battle for Bats: White Nose Syndrome, explaining how the deadly fungal disease was decimating bat populations at an unprecedented rate. At that time it was reported that the fungus had killed over 400,000 bats. Today that number is over 5.7 million, and it is being called one of the most devastating afflictions to hit American wildlife.

The sequel film, subtitled Surviving White Nose Syndrome, remains positive. Some bats are surviving multiple years of exposure to the fungus and looking fairly healthy. In order to study the survivors, bats are banded with year-specific bands to track their health over consecutive hibernation periods. Researchers hope they can glean some answers from the bats that are defying the odds multiple times.

Because the disease has been around for several years now, protocols have been implemented at caves sites around the U.S. At Mammoth Cave in for example, the 400,000 visitors that pass through must step through bio-security mats, which serves the dual purpose of keeping them from bringing pathogens in as well as from taking them home.

Brian Pijanowski, Professor at Purdue University in Landscape Ecology, is pioneering the emerging field of Soundscape Ecology, and he's using Wildlife Acoustics SM2 Song Meters to do so. According to Pijanowski, sounds can oftentimes be the first indicators in a host of changes facing a habitat.

Like an acoustic fingerprint, each environment has its very own sonic signature, and that signature is bound to change with changes in its diversity. Using these aural snapshots, scientists are able to see what's happening in a landscape over time. At first glance, it might seem obvious to track the sounds in an environment as a gauge of biodiversity and ecological impact.

“Over increasingly large areas of the United States, Spring now comes unheralded by the return of the birds, and the early mornings are strangely silent where once they were filled with the beauty of bird song.”
