A genus of large, dark birds of paradise native to New Guinea, known for their elaborate courtship displays and vocalizations.
From Greek 'epi-' (upon) + 'macus' (likely from 'machine'), referencing the ornate mechanical quality of their display behaviors.
The sickle-bird (genus Epimacus) performs one of nature's most bizarre dances—males hang upside down while making chainsaw-like sounds to attract females, using their environment like a concert hall.
