I used to run hounds and have shined a tree or two.I have noticed coons eyes glow a dull yellow and fox eyes reflect blue.I shined a tree one night and thought I had a fox treed and it was my dogs eyes shinning back blue also he had 3 coon treed and was going up after them.I called in a mountain lion one night and it had yellowish green eyes and a bear had a red glow to his.
