    Astrapia

    These indigenous New Guinea birds of paradise have long tails smaller in females than in males

    Phylogenetic evidence reveals that this genus is roughly 6 million years old – sister to two species in the genus Paradigalla.

    The birds of paradise are generally characterized by elaborative courtship displays, as it is not easy to impress a mate. Interestingly, these birds’ morphology, behavior, and courtship displays have evolved over time. A male in courtship might hop from branch to branch, cutely flick his wings with opened tail, or become inverted, showing somersault skills. The males are more brightly colored with elaborative tails; however, the females show more dull plumage.

    Evolutionists are particularly interested in studying these birds due to their exciting evolutionary patterns. Also, due to their habitat, there is still a lot to learn and discover about these birds.
