Through the mist and frosty air : the mills of Kinderdijk on a cold February morning, Zuid Holland, The Netherlands
Birds of prey have a number of adaptations that make their eyesight especially good. The first thing, that is obvious here, is that both eyes point forward giving them great binocular vision for judging distances. Prey species have eyes on the sides of their head giving them all-round vision but the compromise is they have poor binocular vision. Here's a face-on Woodcock, a prey species, showing the different eye positioning: www.flickr.com/photos/timmelling/49683418456/in/photolist Birds of prey also have tube-shaped eyes which increases the size of the image on the retina (a bit like having a bigger screen on the back of your camera). Birds of prey have about five times more receptors per square mm than humans giving fantastic resolution. This is like comparing a 5 megapixel camera with a 25 megapixel camera. The fovea is the part of the eye with the greatest concentration of receptors giving the greatest visual acuity. But birds of prey also have a second fovea in a "pit" which will give an even larger resolution image if they "switch" to using that fovea. Interestingly, Condors which feed by scavenging don't have the second fovea that most birds of prey have, as they don't need such great visual acuity. The Caracaras which feed by walking on the ground also lack this second fovea. And finally birds of prey have a ridge over the eye giving them that fierce look, but this is also critical in protecting their eyes. Look how vulnerable an Ostrich eye is in comparison: www.flickr.com/photos/timmelling/33908387402/in/photolist
This young male Sparrowhawk had just caught a male House Sparrow in my back garden a few days back. I already uploaded a sideways view but this face-on view was dramatically different, so I thought I'd upload it too.
Cooper's Hawk, Glendale, Missouri. I'd prefer a more natural perch for this guy, but I like the glowing orange eye and the background isn't bad...
Photo taken at the weekend of this amazing wild juvenile Goshawk just look at the intensity of those eyes. (Thanks for viewing my photos)
Sparrowhawk in our garden, the image is a bit soft as it was shot through a double glazed patio door. I grabbed this first then slowly started opening the door but it must have seen me & flew away :(

Whilst Q198 did their thing at Joliet Yard, an eastbound IAIS decided to pay a visit with a classic GEVO/SD38-2 pair up front. The right sources kept me up in the action without missing a beat. UD Tower, Joliet IL.
The Big Piney river in the scenic Ozarks region of Missouri, USA. This river bends often and is lined by limestone cliffs and woods. Photo taken from an old Route 66 bridge.
Camera: Brownie Hawkeye box camera manufactured in June 1958.
Film: Verichrome Pan 620 film which expired in December 1972!
Developing: Kodak HC-110, dilution H, for 10 minutes.
This film, which expired when I was a child, never fails to impress. Some of the photos came out spotty, but most were of good quality.
Thank you in advance for any likes or comments!

Kuretake Managaka Zig Pigment pen & Artistro Watercolor on WHS 150 Cold Press Vintage Watercolor paper.
I’ve been using this 70 year old paper without many problems, but on this new sheet the color did not want go down, and would hardly move. Hopefully, it will be the only piece like this.
