Merged summary

TL;DR — MetaPerch is a bioacoustics foundation model that adds recording metadata (e.g., location and time) as auxiliary supervision signals to audio training, aiming for richer, more robust species-identification representations. It matters because it shows freely available community-data metadata can improve generalization for real-world passive acoustic monitoring.

  • Uses audio + metadata (location, time, and other sources) as cross-modal auxiliary losses, exploiting species–metadata correlations rather than vocalizations alone.
  • Targets robustness to species-distribution and acoustic domain shifts, key obstacles for deployment in passive acoustic monitoring (PAM).
  • Reports strong species-identification performance across multiple challenging domains, plus an empirical study of 9 metadata sources across 17 bioacoustic datasets.
  • Builds on citizen-science data (e.g., Xeno-Canto); specific quantitative metrics aren't provided in the abstract, so exact gains can't be stated.
