Wondered about the eyes on the eagle ... must have hit that shutter button just as the eagle "blinked" ... nice shot, nice timing

Bald Eagle's Nictitating Membrane. Bald eagles, like other birds of prey have incredible eyesight. To keep their vision sharp, bald eagles clean their eyes with the help of an inner eyelid called nictitating membrane. Besides protection, the membrane keeps the eye moist and clean of dust.

Great shot and perfect timing!!!
BTW no cataract here, back in the time (in my childhood) I had for a few months young Common kestrel at home - broken wing - and I have seen this membrane in action. And not only the birds have it, last time I have seen this was in lizard (just few weeks ago).

I love the open mouth of that eagle shot. On the topic of blinking birds, here is a picture of Sandhill crane I took a couple years ago.

Thanks, yes its perfectly natural, I don't think all birds have them, but I have some shots of Woodpeckers where it is closed too.

Very nice pictures of this "cool bird"... I especially like the way the dull red / rusty colour comes out in the first one!

A comment about the eagle image above, and its eye ...

Neat photo. Given the very shallow depth of field, I'm curious about the lens you used. It obviously is rather long.

Thanks for the compliments guys. Stevelee, I actually used my old 100mm macro non L version. Luckily they don't scare to easily around here so your able to get very close. You can even feed them, if they are in a good mood. The hardest part was to get the Sandhill crane to look at me straight on. I wasted many shots trying.
