Thanks. Honesly, it’s just not easy to take satisfying bird photos with a smartphone camera, in my experience. They’re really not designed for it, they’re for taking photos of humans, pets, food, and landscapes. Depending on your budget you might consider carrying a bridge camera. See past discussions:

You can always record bird calls (if they’re vocalizing) with the app.
