Thanks all for the answers, I really appreciate it. Regarding the second one, is there anything as a white faced cinnamon glider? I remember stumbling upon something like that on the internet. If something like that exists, is the second one is a white faced cinnamon?
This picture below, is my acquaintance's glider and I know for sure he is a WFB but he is so white. The second pic seems to have a bit lighter brownish color, or is it actually just the same?
