News and Notes by BCM affilates:
Where is BCM? During the 2014 season we have in progress:
- bat capture surveys in MO, PA, IA, MD, KY, and AZ (the majority which were environmental assessments for Indiana bats)
- radio telemetry assistance on Myotis septentrionalis in PA
- radio telemetry on 9 Myotis septentrionalis in PA
- radio telemetry tracking 2 Myotis leibii to barns in PA
- 594 acoustic monitoring sites in PA and counting
- 110 acoustic monitroing sites in NY
'Tis the season for new bat detector comparisons. We are now testing 10 different long-term passive mic configurations from 3 manufacturers in a week long real-world batty environment. We are also making recordings with the new Echometer Touch, watch our reviews section for updates.
Join John Chenger/BCM and Janet Tyburec/JTConsulting test-driving the new Wildlife Acoustics SM3 bat detector. We will be putting these detectors thru their paces at all of our workshops along side the usual assortment of makes and models from Wildlife Acoustics and other manufacturers.
John Chenger, Todd Sinander (BCM), and Dave Riggs (Myotisoft) recently assisted the PA Game Commission with winter bat surveys in several caves and mines. Check out video and photos!
BCM is now supplying the Bat Bunker artifical roost. We made some in-house mods to the shell and increased the capacity to make it a "Plus" for your local bat population!
Where was BCM? During the 2013 season we successfully completed:
~262 nights of bat capture surveys in PA, OH, WV, IA, KY, and AZ (the majority which were environmental assessments for Indiana bats)
~216 nights of acoustic monitoring in PA, IA, NY, OH, KY, and WV
~33 nights of trapping and acoustic monitoring abandoned mine features in PA
~radio tracking on two Indiana bats
~day and night radio tracking on three Eastern small-footed bats
