King-of-Saxony Otherworldly Calls
Throughout their evolution, male birds–of–paradise have been under immense selective pressure to win the attentions of females. Even the King–of–Saxony's extraordinary head wires aren't quite enough. They've had to develop a display that includes waving the head plumes, rhythmically bouncing on a perch, and delivering an extraordinary screeching, buzzing, hissing call that sounds like anything but a bird.
