Spotlight on optional hardware attachments: The SMX-UT ultrasonic microphone

Looking to upgrade your bat recording rig? The SMX-UT is our most powerful and precise tool for omnidirectional bat recording.

As the higher end alternative to our SMX-US ultrasonic microphone, the SMX-UT provides a flatter frequency response and higher sensitivity at frequencies above 60kHz. It records up to 192kHz and it’s weatherproof, just like the standard SMX-US microphone. The SMX-UT has very little reduction in sensitivity off-axis, which means it can record bats in all directions. This is helpful for capturing a larger sampling of bat passes and echolocations.

And if your recording needs require a directional microphone, the SMX-UT is compatible with our SMX Horn accessory. This horn will transform the UT microphone into a highly directional microphone.

A New Way to Tackle White Nose Syndrome: Artificial Bat Cave

The deadly fungus that causes White Nose Syndrome has claimed more than 6 million bats since it was identified in 2006. It has been a crisis for bats all over the Eastern US and Canada. Yet despite desperate efforts by various research groups and organizations, the epidemic has sprinted on at an alarming rate, threatening eventual extinction for several bat species.

Last year, The Nature Conservancy of Tennessee employed an all-new strategy. They built an artificial bat cave. The operation is more complicated than it sounds. The cave needed to have just the right conditions – the wrong temperature and humidity could spell disaster for the already weak populations. It also needed to be free of humans, who have been known to accidentally spread the disease from cave to cave.

We always enjoy hearing research updates from scientists who have deployed Wildlife Acoustics devices around the world. Recently, we caught up with Jared Towers, Minke Whale Research Director at MERS, to hear about the exciting research developments they have made with Minke whales. Here’s what he had to say:

“The MERS [Marine Education and Research Society] conducts research on Baleen whales off of Northern Vancouver Island, in British Columbia, Canada. In the summer of 2012 we deployed a Wildlife Acoustics SM2M near the community of Alert Bay in an area where Minke whales regularly occur. The SM2M was deployed in 70 feet of water for a total of 108 days and programmed to make back-to-back 3-hour recordings. During 54 of these days, we made 568 hours of visual observations of marine mammals from shore less than 150 metres from where the SM2M was deployed. In total, 9 species were observed and 6 (including Minke whales) were acoustically recorded. This kind of shore-based visual and acoustic research has allowed us to expand our study methods of baleen whales and other marine mammals, while concurrently reducing our impact on their behaviour and environment.”
