As I said earlier, the Cedar Waxwing’s tail is tipped with yellow. That’s standard. But I have several photos of Cedar Waxwings with orange-tipped tails. It was very noticeable so I had to do some research to discover the reason.
According to my favorite site for bird information, All About Birds: “Cedar Waxwings with orange instead of yellow tail tips began appearing in the northeastern U.S. and southeastern Canada in the 1960s. The orange color is the result of a red pigment picked up from the berries of an introduced species of honeysuckle. If a waxwing eats enough of the berries while it is growing a tail feather, the tip of the feather will be orange.”
