觀察細節

Possibly heard an Indigo Bunting, recording attached. Compared to the numerous singing Lazuli, it was slower, cleaner (less metallic), and featured paired notes. I spent a lot of time trying to get a visual but had no luck with this skulky one! Due to no visual, leaving as Lazuli/Indigo as this recording alone is insufficient for a reliable ID, it could be a Lazuli after all.
