Using Auto-classifiers
to Determine Occupancy -
What do the outputs really mean?

A Bat Conservation and Management
Bat Acoustic Mini Workshop

Clinton, NJ • January 8, 2013
Preceding the
Northeast Bat Working Group Meeting

John Chenger of Bat Conservation and Management offered a 3 hour acoustic workshop on Day 1 of the Northeast Bat Working Group annual meeting; Wednesday January 8 in Clinton, NJ, from 9 AM until noon. The workshop theme was Using Auto-classifiers to Determine Occupancy - What do the outputs really mean? 

Janet Tyburec kicked off the workshop with a short introduction to echolocation and the physics of high-frequency sound, then allowed the four main US acoustic software developers an opportunity to demonstrate their product and explain their classifier output. Jeff Gruver demonstrated Echoclass, John Chenger demonstrated BCID live, Ian Agranat demonstrated Kaleidoscope Pro live, and Joe Szewczak Introduced SonoBat 4. Chenger presented  examples of real-world survey projects that rely upon auto-classifier outputs and caveats for how to best vet the outputs to provide reliable recommendations, based on our experiences with recently collected field data from across the eastern U.S. PDF versions of most presentations are provided below for the convenience of our participants.
