BCID stands for Bat Call Identification; it is Professional-level software for the automatic analysis and identification of bat species, via recorded audio.
BCID is currently used by several agencies, Ecologists, Professional Bat Workers, and Researchers; to facilitate identification of recorded bat sounds.
I'd written a review of this formidable bat call identification software once before, back in February 2013. And thought it would be a good time to re-visit this application, and write an updated overview for 2019.
BCID has the distinct accolade of being one (of only two) software applications endorsed by The U.S. Fish And Wildlife Service. More specifically, it is approved by The USFWS for conducting surveys, for the following bat species:
The Indiana Bat (Myotis Sodalis) - USFWS Link
The Northern Long-Eared Bat (Myotis Septentrionalis) - USFWS Link
The other software, is Kaleidoscope from Wildlife Acoustics.
At the time of this writing, BCID is available in two versions:
- BCID Eastern USA (which is the specific version being reviewed here)
- BCID Canada
- And a soon-to-be-released BCID United Kingdom
BCID Software has been continually improved in the years following it's initial release, in 2007. Some of the very latest updates, may be seen Here.
It is a Windows-based software (32 and 64 Bit), which allows a user to quickly and accurately analyze large numbers of bat calls.
The user interface is simple but effective, and very easy to use. The current version of BCID is Version 2.8b.
BCID software should be given serious consideration, by anyone in need of a robust, easy-to-use, and accurate bat call identification software.
It is particularly well-suited to Ecologists, Bat Workers, Researchers, and anyone wishing to have bat calls identified.
The easiest way to use this software, is by starting with ZC recorded bat calls. However, as you'll see, .wav files are almost just as easy to process:
- From the default screen, click the 'Add Folders to Project' button, on the lower left-hand-side.
- Drill down to the location of the (ZC) file folder containing your recordings.
- Click the Species tab, and select your Country, and State. Your local bat species will be displayed. The (already checked) names of the bat species, are also un-checkable; if you have the need to omit a species from being identified.
- Click the Project tab, in order to make the original bottom tabs visible again.
- Click on the Identify Calls tab (lower center of screen).
- After (typically) a few seconds, the interface will look like this:
- As evidenced in the screen capture above, when accepting the default software selections, various files are created. As well as the individual bat recordings being converted to .ZC. In my particular case, the .zc files have automatically associated themselves with Kaleidoscope software; which happens to reside on my laptop as well.
- In general, I've always found BCID software to be fast, accurate, and very convenient to use. There is certainly no steep learning curve here!
As seen in the screenshot below, the report files which BCID creates, are in .xls format. I have always found this to be a very welcomed feature; especially because printing the file is so seamless.
For this particular example, I intentionally selected a group of recordings with very little bat activity. For the sake of clarity. Future screenshots, in Part 2 of this review, will illustrate much heavier call volume. Which for many of my readers, is a more common occurrence.
The output (.xls) files which BCID creates, that is to say, it's report/listing of bat species detected, has always been one of my favorite features.
Very convenient! Looking forward to completing Part 2 of this review.
Happy bat detecting!
