Ornamentation is typically exaggerated in the male of the species, as seen in orang-utans (Pongo pygmaeus) and lions (Felis leo). Male birds in particular are typically more brightly colored. An exception is the three species of Phalaropes (Phalaropus) [Charadriiformes] [lower left]: as shown here, the female has a more brightly colored gorget and more distinct markings on the head, whereas the male is more drab. This appears to be due to a different hormone balance in the females.
