Adelie penguins are one of the smaller species of penguins, just above 60.96 cm tall. Their back, tail, head, and face are black. They have a white belly and a white ring around their brown eyes. Their feathers cover half of their bill, which is black with an orange base. They have dull white to pink legs and feet with black soles. (Berger, 2004; Glausiusz, 2007; Grossman, 2003)
