Sandhill Cranes may have decided to venture Northward. Some part of their being has been circling loudly. There's obviously been discussion amongst them, and last night your correspondent heard them calling. Have to think their decision has been made.
In the generations of these particular Sandhill Cranes that pass this way, the
fossil record suggests that they've been making this same sort of decision for
certainly two and a half million years, possibly ten million years. The first
human settlers crossed the Bering Straight into the Americas something like
forty thousand years ago.
