BCID East is a powerful application that allows users to automate the identification process of bats in the Midwest and North Eastern United States. It currently covers the following species:
Myotis austroriparius (testing)
The application interacts with Chris Corben's AnalookW to filter and extract call parameters from bat calls. It then uses several different algorithms to determine which bat most likely is responsible for producing the echolocation file. It can be used with Anabat files, converted full-spectrum files, SCAN'R parameter files and Analook parameter files.
It is extremely fast. The latest test have shown that it will analyze around 40-60 call files per second, depending on the capabilities of your machine. It provides repeatable results. The algorithm will run the same way every time, unless the user specifies differently. This provides an extra layer of transparency for the researcher. It is very flexible. Though it will change your
results, I encourage users to try different settings and compare the quality
of their results. The user is capable of changing settings such as the filter
options, species present, output, Anabat header content, and several other options.
Bats in the wild do crazy things. I describe it as the ability for a person to hit "Hi's" like Cyndi Lauper and "Low's" like James Earl Jones. While this program has been shown to perform extremely well with clean known call files (>95%), field data can still present some difficulties. It is our belief however that the performance is comparable to an experienced human investigator.
