This photo was on the "Daily Dozen" for today on the National Geographic site. Hope this is not a fatal copyright error, but I included the photographer's caption on the photo and her name. This is very unusual! I wonder if many of the eyeshine reports we hear about could be something completely natural and normal... like this owl?

Caption:

The owls' eyeshine is due to a reflection off the Tapetum Lucidum. The majority of primates dont have one. However if Sasquatch is nocturnal its not outside the realm of possibility that it may have evolved in them.

Some light reading for anyone intrigued by the primate visual system can be found at

Interesting. At first I thought it was a trick photo, showing 2 oddly colored baloons against a black wall...

It would explain alot of red glowing eyes 8 feet off the ground.

That is exactly what I thought, Fan.

I have seen unusual red eye "glow" and while I am still not 100% sure, I now believe it was an owl.

What is interesting about this image is the color spectrum. Very cool.

Found a couple of things at Wiki in reference to Tapetun Lucidum.



So some primates do have this feature. Also found this, although not in reference to primates:



Are they talking "Amount" of light that's not visible to humans, or "Wavelengths" of light?

I've been trying to make this point for years but it always seems to be kind of shrugged off. This incredible image illustrates the point very well - thanks for posting!

Me too Saskeptic, but from a "'believer's" point of view. I usually get yelled at. And I am sensitive to forum scoldings. lol

Me three.

OMG, it's orbs! Run, run, the sky is falling. High strangeness everywhere...

It is speculated by some that the Flatwoods Monster was an owl.

Ever seen a whiporwill eyes caught in the light beam of your car or flashlight?

Is that the monster on the left or the right?







j/k of course.

Both "whips" and the more southern "chucks" will often forage along roads. They dash up from the ground to catch an insect in flight and return to ground pretty much where they started from. Not evident from the posted photo, their eyes are "semi-binocular." Their eyes don't quite point directly in front of them as owl eyes do, but they do enough so that typical eyeshine is certainly two red eyes reflecting back to you. If the eyes are all you can see, the effect is of two, glowing, red eyes, that seem to float or "dance" above the surface. This can be extremely creepy for the uninitiated. (It's even scarier if you are a moth.)

Every time I see a purported BF eye shine in video or photo I automatically think 'owl' and often offer that as a possibility, but, like saskeptic, I have noticed it seems to go unnoticed.

Apparently spiders can also have some wicked eyeshine in the woods at night.

Good questions, I found a similar discussion of interference and sound waves to be appropriate to the infrasound argument perhaps too.
