American Goldfinches are harbringers of spring in this part of the world. They arrive about the end of February and you can't tell the males from the females in their winter plumage. But as the month progress the males become more and more yellow. In this shot, there is one male on the right and two females on the left. I took this shot through the window which is dirty and the screen is on the window as well. Goldfinches are a bit bashful and will fly away at the least disturbance. Anyway, the image isn't of good quality but it meets today's assignment for a sign of spring.
