Look at this. I had barely put the peanut butter in the feeder when the downy woodpecker was on it. I still had my hand on the lid when he started pecking away at it! In fact, when I opened the peanut butter block I reached up, with the block in my hand, and three bushtits landed right on the top of the block. I had to brush them off in order to get it into the feeder.
When I took this shot I was about 3 feet from the feeder.
The bushtits, sparrows, and this downy woodpecker are the most relaxed around us, even though we frequently burst through the door heading out to the deck and shriek and wave (we're waving and shrieking at the starlings). We've all come to the conclusion that the other birds know this, because they ignore us now. They remain on the various feeders. Some of them look rather apprehensive, but that's about it.
