Sunset spectacular

The most extraordinary thing just happened. I've been watching a cloud formation to the southeast for a hour, hour and a half. It was interesting and gradually morphed into extraordinary in both a dramatic and sublime way.

All of a sudden a flock of (sparrows?) birds flew to the east. A chill went up my spine. A few stragglers flew in the same direction, then a couple of individuals. The individuals were like drops of bliss dropped into my spine. Then another flock, more stragglers, individuals... over and over again for at least 15 minutes. Hundreds of birds. I've never seen anything like this. I had to sit down, my body was overwhelmed by the experience. Nice.
