I was down by the Missouri river one day to capture the fall colors. When I saw this little guy. This little Chickadee was flying all over this tree pulling the seeds off and dropping them on the ground. So I stood back and started to shoot him. Chickadees are fast little bird. And it was a fun task to keep him in the frame. I was shooting with a Canon 6D Mark II with a Sigma 150/600 lens At ISO-640 at 1/1000 sec. at 600mm. I love the way the fall colors and the sky came out behind him.
