I was surprised to see a lone Pine Siskin at my thistle feeder late this afternoon. It appeared to be a female based on the minimal yellow color in the wings. She really didn't like the House Finch or Am. Goldfinch being anywhere around near her, and as usual for a Siskin was very aggressive toward the finches. I got within about 7-8 ft of the feeder and got good looks at the Siskin just to make sure that I was seeing a bird that I wouldn't expect to be in the backyard for a few more months.
