We are humans, and we have been using make-up for millenniums. Now Flamingos also do. They have a pink oil that comes out from their tail and have figured out that if they role themselves for a long period of time and leave it on that it will make their feathers even more pink and that will make them more attractive! flamingos are always doing this because the sun makes the pink color go away very fast. What is even more shocking is that when it comes to matting season it helps them vigorously. We have seemed to notice that the ''pinkest'' female always lays her eggs first. Now you see that it is not only humans who care about how they look, Flamingos also do! Isn't this cool? Please comment and tell me what you think here is the link from where I got my information.
