Downy Woodpecker
Picoides pubescens
Notes:

Downy woodpeckers are probably the most common feeder visitors. They like suet.

They are calm enough to sit on the feeder as I walk right past.

During winter, I think they hunker down in the bluebird houses at night.

I think the environment should be put in the category of our national security. Defense of our resources is just as important as defense abroad. Otherwise what is there to defend?
