I finally managed to get some decent photos at our new birdfeeder. I was taking pictures as birds came and went, and was only paying attention to trying to get a good shot. I didn't even notice at the time that I was taking pictures of two different species of bird.

While I was processing the photos for this picture of the week, I noticed the (now obvious) difference. On the left is a Black-Capped Chickadee, and on the right is a Red-Breasted Nuthatch.

Technical Details: These photos were taken with my Canon 5D Mark II + EF 100mm Macro at ISO 400, f/8 for 1/100th of a second.
