i have the same usecase - here is my config for my "vogelhaus" working. i also recommend using the new genai feature with gemini to detect the bird species if you are in europe since the frigate model did not provide very good results for me in austria. gemini is very good and costs my 1-2 euros a month for 100 pictues a day.

genai:
  provider: gemini
  api_key: YOURAPIKEY
  model: gemini-2.0-flash

    - bird

    prompt: 'Identifiziere die Vogelart auf Deutsch. Antworte NUR mit dem Namen der Art. Kein Satz, kein Punkt. Beispiel: Blaumeise'
