Cedar Waxwings [Bombycilla cedrorum] are beautiful birds with a diet that includes a lot of fruit. They can survive on fruit alone for months at a time. If they are not careful of fermented fruit, they are susceptible to alcohol intoxication and could even die of alcohol poisoning.
Starting around the 1960s, some Cedar Waxwings were found with orange tips on their tails instead of the usual yellow. This is due to a red pigment found in an introduced honeysuckle species that will turn a growing tail feather orange.
