It is very slooooow. like Seaducktor said, for the most part, the birds are stale. I certainly do not believe that we had a big push of migrants go by already, haven't seen or heard of that.
We need the weather up in Canada to get real nasty, that will chase the birds off, and bring them down. If it's a mild winter up there, you won't see very much down here, maybe some pockets of birds here & there, but that would be it.
