Like some kind of karmic balance, it has often been remarked that the more plain-looking a bird is, the more beautiful its song, whereas those bestowed with gorgeous plumage tend to have simple calls. Research across hundreds of bird species has revealed a negative correlation between these traits, suggesting that there may be a trade-off in visual vs. acoustic signals when it comes to attracting mates. Likely falling at one end of this spectrum, Birds-of-paradise certainly are among the most extravagantly ornamented species in the world, but their highly varied calls often consist of harsh squawks and penetrating whistles, which although extremely loud are anything but melodious.
