• Cedar Waxwings are the most specialized fruit-eating birds. Rather than regurgitating the fruit seeds, they eliminate them with their waste.
  • Orange, rather than yellow, terminal bands now seen on some tails are attributed to pigments found in an alien honeysuckle fruit introduced to their diet.
  • A group of waxwings are collectively known as an "ear-full" and a "museum" of waxwings.
