Carol & Jeff,
I have never seen this variation before and the presence of the
bird for a whole month makes the mudbath idea unlikely.
However, I do know that oftentimes genetic color anomalies are not
necessarily body-wide. Many birds (and other animals) with a single,
simple abnormality in the pigment production mechanism show abnormal
coloration in only one part of their body. A human example would
be those individuals who are dark-haired but have a streak of white hair
in the front. This is due to a very specific genetic sequence.
Sounds like this bird is certainly worthy of photo-documentation. It
would also be interesting to see if it sings a normal Carolina Wren song
and if it pairs up with a mate in the spring.

p.s. A Carolina Wren at a feeder ? What does it eat there ? Suet ?
