The past three days I’ve watched a downy woodpecker excavate a hole in a dead ash tree. Its characteristics are a near perfect match for the Cornell website description of a preferred downy cavity - a short section of branch around 7 inches in diameter, hole on the underside, etc.
I’m assuming this is a winter roost. What I can’t find info on, however, is whether they might then use this in the spring as a nest cavity. It seems like an ideal nest site (again, per descriptions at Cornell & Wikipedia). And we can easily see it, so a nest there would be fantastic.
We’ve intended to cut down the tree for years so it doesn’t fall on the woodshed. Our laziness has been rewarded. :-)

If you have any photos as this progresses please link the observations you make! I would love to see some updates.

I have video and am planning to pull some still images from that. If I can remember to bring out my camera rather than my phone, I should be able to get better photos. :-)

I don’t know about Downies in the particular, but many birds avoid using the same cavity for too long because of the buildup of parasites. I wouldn’t be surprised if they move out in the spring, or even part way through the winter, once the parasite load becomes too much.

That would make sense. It always surprises me that our barn swallows reuse nests, and those nests are, in fact, susceptible to mites. Thanks!
