Where birds go in winter.

Ever wonder where birds are going when they fly south? I think it's the open fields around little rock, ak. There must be hundreds in every clearing. It's really strange. I think they looked happy reuniting with old friends. I tried to snap some pictures, but the flash alerted four of them that followed along the car a little way. I think they were the sentry guards. I'm glad we didn't stay around to find out.
