Basic Guidelines: In the strictest sense, nature photography should not include "hand of man elements". Please refrain from images with buildings or human made structures like roads, fences, walls. Pets are not permitted. Captive subjects in zoos, arboretums, or aquariums are permitted, but must be declared, and must focus on the subject, not the captivity. Images with obvious human made elements will likely be deleted from the thread, with an explanation to the photographer. Guidelines are based on PSA rules governing Nature photography which also cover the Nature Forum. Keep your image at/under 1000 pixels on the long axis for in-line viewing. Note that this includes photos hosted off-site at Flicker, Photobucket, your own site, etc.

Each member please post no more than just one image to this weekly thread per week. If the information is available, many members appreciate information on your approach to making the image and the names, both common and scientific, of the subject(s). However, while encouraged, these are not required as a component of your contributions.

I particularly like how you can see the transparent nictitating membrane half covering the eye. Presumably for protection. It'd be interesting to see if the membrane usually covers the eye when catching prey.

It does as one of its primary functions is to protect the eye (while still maintaining vision). Another is to keep the eye moist. When observing ospreys this year, I noticed that they deploy their nictitating membrane quite often - interestingly about every time during a large head turning movement.
