Many birds make use of black plumage, whole or only partially. In feathers it is melanin pigments that produce the black to reddish-brown colour, these pigments are enclosed in granular structures called melanosomes. The melanosomes make black feathers stronger and more resistant to wear than non-melanised feathers, and often birds that have mostly white plumage…

In 2007, I traveled backwards in time. As I dove below the surface of the water at Cocos Island, two giant and curious sea turtles gracefully greeted me.  By the time I reached 30 meters below the surface, I found myself surrounded by hundreds of hammerhead sharks, another ancient species whose ancestors outlived the dinosaurs. …

Bird plumage assists birds with more than just flight; colour is often used as a signal of quality, and readiness to mate in the breeding season.
