all the birds are leaving

I've said more than once on this blog that not only do you start to notice when seasonal phenomena arrive, but also when they depart. Spring mornings are full of the sounds of song birds, but now the sunny mornings are silent. I don't know if the birds have actually started their fall migration yet, or if they are just quiet because they don't need to establish their territory now that the breeding season is over.

Across the evening sky, all the birds are leaving.
But how do they know it's time for them to go?
Before the winter fire, I will still be dreaming.
I have no thought of time.
For who knows where the time goes?
Who knows where the time goes?
