bearded vultures are known for their vibrant red coloration. however, this isn’t their ‘natural’ color; it is derived from red clay the birds rub onto themselves as a status symbol (the darker the color, the higher-ranking the bird). when bearded vultures aren’t provided with clay, they are white like this bird.
