The American Tree Sparrows have arrived in my yard. I had just one last week, but yesterday there were three. The Dark-eyed Junco's are around on a daily basis as well. I have had a high of twelve so far this winter.
Overall yesterday, it was a sparrow afternoon. A Song Sparrow has been sticking around these last few weeks of November. There were actually two yesterday and I was also surprised to see a White-throated Sparrow. We had quite a bit of snow (probably at least 25 cm) and by the time it stopped at noon, that's when all the sparrows showed up.
