AOU Checklist Supplement

I don't even have time to read it, as I'm extremely busy this week preparing for the AOU conference and for my 3-week long megatrip (more on that before I leave), but here is the 48th Supplement to the AOU Checklist of North American Birds. Perhaps I will have time to comment on it before school begins, perhaps the next checklist will be out before I have some free time.
