Catmandoo Posted January 9, 2022 Posted January 9, 2022 Polar bear hair comes up again. Polar bears do not show up on infrared imaging equipment. The Canadians learned about that many years ago when an attempt was made at aerial surveys with infrared cameras. Not to worry, there are about 30,000 polar bears today. The web sites about fly tying ( fly fishing ) have good information on hair types and structure. Elk, deer, moose, pronghorn etc. Non of the aforementioned animals have cloaking abilities but they do very well in hiding from humans. Simple browns, blacks and grey work well. Sumatra tigers are an interesting combo of colors for their environment. How about zebras? Nature has done well. 1
