If you live in the northeastern US and were considering birding this weekend, go ahead and get out there. We've had two recent bouts of strong SW winds around here (good for western vagrants), and we're now finally going to get some good migration weather which should concentrate birds along the coast (particularly at our east-west coastline here in Connecticut). There may be a few rarities mixed in there.
Besides, it's going to be beautiful outside...clear and cool with light winds.
I'll be working, but hopefully somebody finds something good enough to make me jealous that I can't be out there.
