Orthoptera recording
Hi,
I need to record Zeuneriana marmorata, a cricket endangered of extinction in Italy that I am trying to translocate.
The aim is to leave the recorder in different localities and compare the 24h automated recordings.
What kind of product do you suggest?
How long can your device record?
Can you suggest reference literature on Orthoptera that used your device?
Thanks in advance and best regards
Filippo

Hi Filippo, To capture the whole spectrum you probably need to record at 192 kHz. We'd normally use recording periods of multiples of one hour with 5 second sleep duration and 59:55 record duration. That way each recording will start on a round hour. At this rate, 24 hours of recording will generate about 33 GB of data so you'll need quite large SD card (use SanDisk Extreme SD cards only). It will use 580 mAh of battery capacity so you'll be able to record continuously for about five days with good alkaline batteries and 256 GB SD cards.
If you know the times at which the bush cricket will likely sing you can set a more precise recording period and extend the duration of the deployment.
This is a recent paper that used AudioMoth for recording and classifying Orthoptera:

Let us know how it goes.
