[Note Guidelines] Photographer's Note
This is Arrow, an Auger hawk (or Auger Buzzard) from Africa, another bird that I work with. I thought this picture was definitely a little creepy, but also really neat, in that it shows the capabilities of their third eyelids. The birds all have a third, filmy, eyelid that protects their eyes when they fly. They will blink with it just like we blink ours, even while they are sitting still. This picture showed how they are able to manipulate each separately. His right eye is normal, but his left eye shows the intricate little veins in his third eyelid that is blinking on that eye.
I hope you find this picture as interesting as I did! :-)

Hi Steph,
I've seen this before, it's what allows the hawks to drop into such high-speed stoops and catch the slower birds mid-flight (you obviously know that already!) although I didn't know they could control them independently. Some nice detail in the image and a good exposure, although a shame about the beak and top of the head being out of focus. It looks like bird movement as the eyes are focused. An interesting post, thanks for sharing.

Hi Steph,
I do find your photo to be interesting and helpful for the information in your note has answered a question in my mind about some of my own photos.I thought that the birds I photoed with this look in their eyes had cataracts but now I know differently.I think you were a little too close to your subject as it has already been mentioned the focus on the beak is weak,but the details overall are great.Tfs.
