This Cedar Waxwing was photographed at Village Creek Drying
Beds, Tarrant County, TX on 1 May, 1999 by Martin Reid. The orange
tip to the tail of the lower bird was immediately striking, and
it was seen a number of times as the flock of 50+ birds fed in
the willows. The Travis
Audubon Society web site used to mention a report of such a bird,
and states that this color is thought to occur when young birds
(with still-growing tails) feed on the fruit of Morrow's Honeysuckle,
a non-native plant grown in the north of the USA that contains
a red pigment called rhodoxanthin. The report says that there
are no other records of this rare(?) form from Texas. Interestingly,
Morrow's Honeysuckle is native to Japan and the Japanese Waxwing
(Bombycilla japonica) has a red tip to the tail (click

Any comments? Update: November 2006: I've heard from a biologist in San Angelo that he catches good numbers of Cedar Waxwings each winter, and that 2 - 3% have orange tips, with no apparent intergrades. He feels that this suggests a (genetic) mutation may be at work. |
