I live in Southeastern Pennsylvania, so wouldn't it be a little cold for
this bird? The last week has been warm (45-60 degrees) but I can't imagine
it getting enough food. It's apparently been around for a couple of weeks.
I'm actually excited, it's the first time this has happened. I'll try
to get some pictures.

umm you might want to check your fish pond.

Pix would be nice!
