The birds have gone away.
I think magpies symbolise something, but I'm too dumb to work it out.
I watched three attacking a galah in the air a few days ago.
The galah spit around, disoriented not sure what way to fly, going back and forth in a star pattern for at least 5mins.
Then the magpies flew off after harassing it and went in almost the other direction.
Probably a metaphor for emotional trauma.
