The one I remember seemed real, but it was too similar to the “convo” I “heard” earlier this week. I was falling asleep on my left side again and heard birds over the road construction outside my window.
One whistled more clearly and didn’t sound like the other birds. Its whistle sounded like the mocking jay tune from the Hunger Games movie, but off by one note. I thought it was interesting. It repeated the tune, but correctly this time. I woke up to post a Facebook status about it and the bird, if real, stopped whistling.
