OK, I know this is hard to believe, but in the hour and a half since I wrote that bit about the huge numbers of cranes, I saw 1300 more. (Yes, that's the correct order of magnitude.). So that brings the day's total of birds I saw to 2,340 -- but I'm confident that the 3 flocks I heard but didn't see brings that up to 2,600 at least -- plus all those that flew over while I was inside and didn't hear them. Totally amazing!
The sun is now down and it's getting cold so I'm assuming they're done for the day. Oh no, there's another flock flying over right now.
