Chirp Trail: Offline Bird-Call ID Device Uses Local AI for Hikers

Chirp Trail is an offline bird-call identification device designed for use in areas without cellular service. It records brief audio samples and uses local AI models to identify bird species and generate explanatory notes. The system combines BirdNET-Analyzer for audio classification with small language models like Gemma or Qwen for creating field-guide descriptions. All processing occurs on-device using a laptop or Raspberry Pi, with sightings saved to a local trail log. The tool targets beginner birders, hiking groups, and educational nature clubs.
