This is a topic that comes up with some regularity, especially in the spring. When I incurred about the brown Hairy Woodpecker coming to my feeder a few years ago, I was told it was staining from the nest cavity! This makes perfect sense in hindsight, as the hole is going to be as small as possible to keep predators out and we all have experienced the sap and resin that seeps from recently cut branches. A cool phenomenon!
