Blockquote Case study I: Suivi des Orthoptères Nocturnes (France)
In France, nocturnally vocalising bush crickets have been monitored by citizen scientists since 2006, as an add-on to the acoustic bat monitoring scheme Vigie-Chiro (Figure IA). Tadarida software was developed to detect both bat and insect calls and classify them into 79 classes, including all common bat and bush cricket species, using a random forest algorithm [101]. This nationwide monitoring scheme, with (so far) 16 349 individual sampling locations, has detected significant declines of several bush cricket species [34].
This is such a positive development for monitoring and studies.
I’ve been hoping that orthopteran sound ID apps will become more common. In addition to France, in England and Ireland there’s iRecord Grasshoppers, & sounds like there’s something for Germany (don’t read German, so don’t know for sure). Nothing I can find for north america.
An additional problem for this kind of app is sorting out individual calls from the soundscape of a warm late summer evening. Even Merlin has problems with overlapping bird songs.
In Holland we would use a UK website which was originally for bats but included all sound from mammals and orthoptera which could be heard at night. Due to much effort the use is more limited these days. You upload the sound in the cloud to Tadarida and you get the results (bats, mammals, orthoptera) return with a focus on UK.
But does https://irecord.org.uk/ include sounds ?
I thought that they wanted to develop their own open source data base and that they needed certified, controled, determeid .wav files to build their recognation database.
I´ve been waiting for orthoptera sound identification tool since the emergence of BirdNet. If it exists for birds, it could work for insects as well, am I right? Thanks for sharing this.
