Dyeing Poison Frog (Dendrobates tinctorius). The name stems from the early belief that Amerindians used the toxins from the frogs to change the colors of parrot feathers. The alleged practice entailed stripping parrots of their green feathers. Skin toxins from the frogs were then rubbed on the bird's skin. The feathers that grew back were red. No substantial evidence has been provided for this process, known as tapirage. The species is found through the Guianas and adjacent Brazil. It is a polymorphic species with dozens of colors and patterns. These frogs were photographed in 2008 courtesy of the Atlanta Botanical Garden.
