This was the fourth in a series of five shots taken in about a second. The first and fifth shot the bird's head is upright as normal. The second shot it is slightly cocked and the third shot it is at about 90°. In the field I didn't even see it and didn't know I had this shot until I got home and had it on my computer.
On another note, I have just added another photo. This should be posted in the "Bird ID" section, but I didn't want to confuse posts. It was taken shortly after the Boney at the Nonquon Lagoons. I originally thought it was a juvenile Yellow Warbler, but now I am not sure. Any help would be appreciated.
Thanks.
