RE: [nysbirds-l] interesting woodpecker

2014-05-06 Thread SUSAN HERBST 
A couple of years ago, we came across one in NH. It was a frequent 
visitor to a friend's yard. We did some research and there were a couple 
of theories. One was that it was stained by what ever tree it was living 
in and another was that it was diet related. Neither scenario explained 
why none of the other hairys in the area were yellow tinted.

The phenomenon is called xanthochromism. Not much seems to be known about
it, except that it is fairly commonly observed. There are some hypotheses
that suggest that the cause is often environmental and perhaps dietary in
birds.
