Hunger is making them pretty aggressive, too. I was in the back yard and started to hear lots of chirping and wing flapping. When I looked up, I saw a lot of fussing going on. I was able to get this shot of two of the house finches trying to get the best spot on the feeder.
I was pleasantly surprised to see some more song sparrows in the yard. The were not serenading me, but they were very watchful. From the kitchen, I can't really tell the difference between the house finches and the song sparrows, and when I saw the stripes on this one's head, it was very exciting! I thought our entire yard had been taken over by the house finches!
