Bigfoot - Infrared

Still capture of an adult holding infant in front -2010
The eyes of a Bigfoot are very interesting. They appear to be like dog or cat eyes. Dogs, cats and other animals possess a light-reflecting surface known as the tapetum lucidum, located between the optic nerve and the retina. It operates like a mirror, reflecting the light and allowing the rods and cones another opportunity to pick up the limited amount of light available at night. This explains why their eyes glow when a light source hits them at night. This also would explain why they sometimes glow on their own with no apparent light source. Even on the darkest night with no moon there is still light present. It may be very slight starlight but it is there. Since the Bigfoot’s eyes are picking up this light and reflecting it, it often gives them the appearance that their eyes are glowing at night.

Hiding in the shadows
I have also noticed the eyes will appear reflective during the day when they are hit by sunlight. This is especially apparent when the Bigfoot is back in the shadows and leans out to take a peek around. The eyes will glow very brightly.

I think the Bigfoot can also see light in the Infrared (IR) Spectrum. I say this based on two factors. The first is their ability to avoid game cameras at night that use IR to illuminate the immediate area. The second comes from a trail camera video I captured in 2009. One Bigfoot was peering at the camera from thick vegetation. A second Bigfoot shook the camera then waved its hand in front of the camera. The IR light bounced back off the camera causing an “IR Flash” that illuminated a wide area of the night. During this flash the eyes of the Bigfoot that was observing from the safety of the vegetation reacted to the IR light. The pupils retracted almost to pinpoint. Then as the IR light returned to “normal” the pupils adjusted and dilated.

On a side note, critics have claimed the video I reference is no more than leaves and shadows, an illusion, or pareidolia. When I point out that this subject has two eyes that have pupils that can be easily seen and react to IR light there is silence. This issue is never addressed in their criticisms. Usually the critics switch to personal attacks or just incoherent rants filled with expletives when I point out the “clump of leafs and shadows” has moving, light reacting eyes.

The eyes are the first things I look for when I think I have captured a Bigfoot on video. Eyes cannot be created by pareidloia in the brain. If those eyes reflect sunlight, glow, blink, move, or the pupils react if the light changes then I know I have a biological entity, not an optical illusion.

In the field I look for this “eye shine” when I think I see something suspicious. The Bigfoot will try to stay down wind with the sun at their back if possible. The wind is always more important than the sun direction. This at times puts them where the sun is shinning in their eyes. This is the time they are vulnerable if you know what to look for. Many times their hiding positions will be exposed to morning or evening sun and this is another time when they can be vulnerable. I use the word “vulnerable” loosely. It means you can locate their position but getting close to them is another issue. Each time I have managed to locate a Bigfoot by their eye shine they have been in a high ground position above me or hiding in thick vegetation that I could not easily access. When I would attempt to move toward them they would slip away long before I was able to reach their position. I have also witnessed Bigfoot actually closing their eyes when trying to hide from me. I think they are keenly aware of this vulnerability and do this to limit their exposure when we get close to them.

There is still much to learn about the Bigfoot and their biology. The definitely have many advantages over us and I believe their eyes  are one of their greatest advantages.


  1. Amazing work you are doing. Have you ever attempted communication with them through thought?
    Sending a thought of friendship, kindness,a hello. Ask if they can come closer?

  2. Outstanding Scott!! Some of the best work I've seen yet.

  3. Based solely on a pre-episode of "Finding Bigfoot, Season 3", when a short clip of the entire "Finding" team (I counted eight people including the BFRO Team Members) was walking single file into a proposed "investigation" area, anyone with I.R. (Infra Red) vision would be able to see this group from a half mile at the very least.
    The reason for this is that every member of the team, be they camera-men to sound-men had an I.R. lamp attached either to their heads or their backpacks as do the BFRO Team Members.
    It seems to me that if the Bigfoot can see in the I.R. range of the spectrum, then these I.R. lamps would illuminate the "Finding Bigfoot" team as they tramp through the forest, always keeping a safe distance from the investigators.

  4. I really enjoy your work. Your passion and intelligence shine in all that you put out there. I love the way you break everything down so that even a first grader could understand. Thank you for all your hard work and please keep up all the great work!!

  5. I think you`re one of the most knowledgeable people in the bigfoot research field...all the insight and analysis of infra-red,ultrasound etc has to be way beyond anything considered before by any "pro" or`s greatly appreciated by guys such as myself that don`t even live on the same continent as yourself...thanks.

  6. What would you say could be an explanation of a VERY subtle fluttering or pulsating of light when being viewed by BFs in complete darkness? I caught a glimpse of amber eyeshine while on a mini-expedition in FL. If it was, in fact, BFs that were observing us, I did notice a subtle flickering/fluttering/pulsating light in the entire area in which we were located. I felt as though I was being scanned. Has anyone ever noticed a similar experience?

    1. I did experience this tonight. Like you are sitting there turning a switch on and off quickly!

  7. Scott thanks for your passion and the time it must take to figure these things out then publish for all to read i speak for a lot of people in saying God Bless you man. Your critics are jealous that you have staying power in this field it is obvious your on the right path to uncovering the mystery of these ancient people. Have you tried mirrors with your cameras it seems to have worked in some cases.

  8. I've found that nocturnal animals are quite sensitive to IR light. The IR illumination that my Bushnell Trophycam HD's emit are undetectable by humans, but foxes, coons & deer react strongly to it, and I'm sure that the 'squatches can see the light from a distance and have been avoiding them.
    This year I've moved the cameras and covered the light elements with two layers of black tape. I'll sacrifice any nighttime photos in the hope of making the cameras less obvious at night. I should still get some good early morning or early evening shots of the big guy while there's some light to shoot by.

  9. On the forum at Sasquatch Research Association a tread was dedicated to discussing theories about sasquatch trail cam avoidance, and the issue of them seeing iR light was also discussed, among other possible theories. It is under the section "Sasquatch Theories."

  10. Have you thought about a game camera that uses a laser-trip to trigger IR light and recording? You could set up a laser perimeter in the camera's field of vision with bait in the center. If Bigfoot can see infrared light emitted by the camera's motion detection this may be a viable alternative. Just food for thought I guess.

  11. Don't know if my comment was saved. Curious what Camera/video is the best. and does it need SIR or DIR infrared system. Love your website, and doing a great job. Thanks...Cheeversbeliever
