I have two Hairy woodpeckers - one male and one female that are nearly goldfinch yellow where the white feathers are - I'm assuming from the sap of the nest cavity. Here's a link to what I think is a downy with the same condition. What types of sap create this? Looking to learn more! http://www.flickr.com/photos/26210288@N08/?saved=1 Thanks!
