We had an evening walk and had the app on as we walked and it identified 11 different species. The last, on our return, was tawny owl which had a red dot against it. Perhaps the app was doubtful as it was not actually dark, but it was very close to sunset and we could hear the owl ourselves, and that’s one we have heard before. I expect we will hear it again at bedtime, when t won’t be competing with the blackbird, robin and song thrush.
