No they don't make it to the morning for birds. In fact I just made this post less than 2 hours ago, right after I realized there were a bunch in my house and went out to see the swarm outside .....and it's already over now, not a single one flying around the street light. They've dropped their wings and are coupled on the ground, then I reckon the males die and the females go underground to lay eggs, then probably die too. Just a guess. I have a biology degree with zoology focus, but entomology is a whollllle huge part I'm pretty ignorant about (except mosquitoes; I was lead field tech for a West Nile virus surveillance study in Little Rock several years ago, so I learned an absurd amount about them).
Here's a pic of a loving termite couple that tried to crawl up my britches a few minutes ago, and a dropped wing. It's weird how they copulate head-to-butt like that, but they are definitely connected; she is just dragging him wherever she wants to go! 🤣
