Description Afterwork: Border, cropped, contrast, sharpened.

Sight is an eagle's most important sense. Scientists believe that an eagle's vision is as much as six times sharper than a human's even though the eyes are approximately the same size. The relatively large eye to head size is not obvious because most of the eye socket is surrounded by the skull. In fact the eye consumes so much of the skull that there is little room left for the muscles that move the eye. The eagle can compensate for the lack of eye mobility by rotating its neck. The large number of cervical vertebrae in the neck enable it to sweep a 270 degree arc.

Even though an eagle's eyes are located on the side of the skull, they protrude outward and their position is far enough forward to provide an overlapping field of view. This allows a degree of binocular vision and its associated depth perception. The ability to accurately perceive distances is critical when diving for prey and snatching it with talons.

The cornea or outer surface of the eye is protected by a ring of bones called the sclerotic eye ring and by two eyelids. The outer eyelid is similar to a human's and is closed from the bottom when sleeping. The inner transparent eyelid is called a nictitating membrane. It protects and keeps the eye moist and clear by flicking across the eye sideways every three or four seconds. Eagle parents often pull the membranes over their eyes when feeding their young. This prevents the eye from being accidently injured by the chicks when they lunge for their food.

The extremely soft lens of the eye allows for rapid accommodation. This ability to quickly refocus between near and far assists in prey identification and self protection. In addition, the eyes are partially atonomous which allows some independent monocular vision to the sides.

I've missed my eagle the past couple of times I've went out there. He's always a highlight. Thank you. I'm putting up a peregrine falcon today.

Ohh you should have seen him this past week, during our Christmas at the Zoo with a friend of mine. Him and the crow were battling each other. Well the crow kept trying to steal a feather and he kept mantling. I snapped some more shots, but the lighting wasn't the best that evening.

I think they need to rebuild his habitat honestly. Make it more expansive.

I so agree with you on that! At least so that he can spread his wings without bumping something....
We got to see him at night last Sat at the lights festival.....

I have a feeling we will have to time it on purpose..... by the elephants or birds of pray....
By the way... what happened to the Eagle? Have you seen him???

No. But one of the handlers told us last time he'd been taken off the exhibit and retired. They are trying to negotiate for another one.

He was so awesome too, trying to avoid the dude cleaning up his habitat and squawking angrily at the vulture next door.

Luck, or rather lots of planning. You see if you bundle up and go to the Zoo when no one else is there, most of the animals are alot more active, especially in some of the cooler months, plus early in the morning is feeding time.
