The King Penguin is the second largest of the penguins, and is a tall, stately bird with prominent orange and black head-markings. The eye is fawn to dark grey-brown, the bill is long, slender and black, and this species is recognised by an orange to yellow ear patch shaped like an inverted teardrop, a yellow tinted upper breast and an orange streak along the lower bill. Females are slightly smaller than the males, and juveniles are slightly duller in appearance.
