The color yellow is sprinkled all throughout the natural world. It can be found in every group of animal, in plants and fungi and let us not forget the sunshine that rains down upon us all from space. Yellow has different reasons for being in all of these places, some you may not expect. Let us brighten your day with the Golden-lion Tamarin and the Egyptian Vulture, each yellow in their own right, owning it in their own unique way.
