The cranes are back

I caught these two out of the corner of my eye when I was driving to work this morning. Had to back the car up to get a picture but they were far enough away that they didn't seem to mind my presence. I wonder if they're the same two I've seen several times before and I wonder where they came from - I don't think Pennsylvania is in their normal migratory range, according to what I can find. But I'm always happy to see them.
