This is the closest I've ever been to a bufflehead. Normally they are way out on the lake. This time as I was walking the shoreline, I accidently flushed her out of the rushes. I took a shot as she swam further out in the lake then dived and disappeared. She seemed to be alone. For a long time I thought female buffleheads were babies or juveniles due to being so much smaller than the males but they are adults, just small and cute. Immature males look similiar but would be larger than she was.
