It is definitely sparrow migration! There are always lots of sparrows at our feeders. It is also definitely fall. We had our first frost the other day. I really love autumn, but I say that about all of the seasons.
Harris's Sparrows are one of my favorite sparrows, especially in fall plumage. Here is a Harris' Sparrow beneath our feeder.
