The Northern Rockhopper Penguin (Eudyptes moseleyi) inhabits mostly the southern Indian and the Atlantic ocean. It is also called the Moseley's penguin or Moseley's rockhopper penguin. This penguin has high vocal and visual communication signals such as loud bray, slapping each other with their flippers, and bowing and preening movements. The head and dorsal surface have black feathers, while the belly and chest are white. The eyes are bright red, bill orange-red, thicker and heavier in males, while the head plumes are long and yellow. The edges of the black flippers are white, while the feet are pink with black or grey claws. Juveniles have less showy plumage.
