Handy blog on eyeshine, important to understand when squatching at night…
Eyeshine in animals is produced by a special membrane, called the tapetum lucidum (tapestry of light), a reflective surface that is located directly behind the retina. When the small rays of light found in the night, like starlight or moonlight, enter the eye, they bounce off the membrane, giving the eye a second chance to use the light. For animals that have this membrane, it is like having a built in flashlight that lights a path from the inside out.
The tapetum lucidum, coupled with big eyes and lots of light-sensing rod cells, allow nocturnal mammals to see well in dark or dim conditions. But eyeshine isn’t limited to mammals. Once, while at the edge of a pond listening to the midnight chorus of frogs, my flashlight caught the glimmering, emerald-green eyes of a huge bullfrog. And in my obsession over eyeshine, I am eagerly looking forward to the summer, when I will be searching the forest floor for the ruby red glow of a wolf spider’s eyes. I only wish that my eyes would glow, a fierce sapphire blue in the darkest of night, but although humans have many interesting adaptations, good night vision is not one of them. Our abundance of cones and lack of rods mean we see more colors than most other animals, but we can’t see in the dark. And we don’t have a tapetum lucidum – when our eyes appear red in photographs, it’s a reflection of the camera’s flash off the red blood cells of the choroid, which is a vascular layer behind the retina.
Eyeshine color varies by species, from the amber glow of a bobcat to the red glint of a black bear. The different colors are produced by the mineral content and the structure of the tapetum lucidum, as well as varying pigments in the retina. There does seem to be some overlap of colors, like bobcat and raccoon having yellow/amber eyeshine.
So is it at all possible to identify an animal by eyeshine color alone? According to ecologist and long-time tracker Dr. Rick van de Poll, eyeshine is somewhat variable so that even within the same species the color can look a bit different. Factors that influence individual eyeshine color, according to van de Poll, include the age and individual chemistry of the animal, as well as seasonal variation and the angle and intensity of the light hitting the eye. But this doesn’t deter van de Poll from using eyeshine as a clue to identifying mammals. “It’s part of the information” he said, “but you have to also be paying attention to the animal’s behavior, the shape and placement of the eyes, and how the animal moves away from the light, or if it even moves away from the light at all.”

"Seven and a half to eight feet tall. And we just started screaming, we were banging on the truck trying to get our parents to stop because we were kids, nobody was going to believe us. And we used to run those woods all the time in between my house and her house. And after that, I said no more, I'm not going back in those woods. It could have snapped us like a twig if it wanted to," Killian said
