[more info]
This value is used by the model to constrain the list of possible species that it will try to detect, given the minimum occurence frequency. A 0.03 threshold means that for a species to be included in this list, it needs to, on average, be seen on at least 3% of historically submitted eBird checklists for your given lat/lon/current week of year. So, the lower the threshold, the rarer the species it will include.
If you'd like to tinker with this threshold value and see which species make it onto the list, please click "Update Settings" at the very bottom of this page to install the appropriate label file, then come back here and you'll be able to use the Species List Tester.you can use this tool:
- BirdNET_6K_GLOBAL_MODEL (2020)
- This is the BirdNET-Lite model, with bird sound recognition for more than 6,000 species worldwide. This is the default option and will generally work very for people in most of the world.
- BirdNET_GLOBAL_3K_V2.3_Model_FP16 (2023)
- This is the BirdNET-Analyzer model, a newer work-in-progress project with aims to improve on the BirdNET-Lite model. Currently it only supports about 3,500 species worldwide, meaning for some regions (North America, Europe, Australia) it will usually outperform the BirdNET-Lite model, but for other regions it will be worse.
