|OldBird 21c Mic|
Since April 2012 I've been recording and monitoring birds migrating over my home in Hunterdon County, NJ. I use an Oldbird 21c microphone mounted on a chair in my yard, and I record each evening's flight with Easy Hi-Q Recorder on a laptop computer connected to the microphone. Sometimes I listen to the recording in progress with headphones, and watch a spectrogram of the recording in progress on Raven Lite. In the morning after the recording is done, I
- Run autodetection software (Tseep-X and Thrush-X) on the recording to locate potential bird calls, which I then
- Sort through manually using OldBird GlassOFire software.
- Sometimes I also review a spectrogram of the recording again in Raven Lite to locate bird calls not picked up by the autodetections software.
- After bird calls are located and saved as separate sound files, I then identify them by referencing both published and online night flight call libraries, as well as other bird call collections such as xeno-canto.org.
- I am currently publishing reviews of nightly migration events here on the Birdchaser Blog, and entering NFC counts in eBird.
