They Sparkle and Fly, Just Out of Reach

I've been out, catching an eyeful of yet another meteor shower. A lot of the more restless stars are up and zipping about this time of year. More now than in, say, the Winter and Spring. I have yet to see a good explanation.

What gets them up and going now? Is there more energy in the air now than there is in the Winter and Spring? Do they migrate in the Winter to another part of the sky, somewhere beyond Equestria? Or are they around always, but the kind of events that they observe don't happen in the Winter?

They do not talk to me.
