Fairy Bluebird - a dimorphic species, meaning that males and females differ in appearance. Male fairy bluebirds display bright blue and black colors, while the female is a duller blue. The brighter colors of the male birds help them attract mates.
Screaming Piha (Lipaugus vociferans) is found in the middle and lower levels of the South American rainforest. Although typically a solitary bird, the males form large groups during mating season as they attempt to impress females with their calls.
