Eastern Bluebirds Knocking on Our Windows

Photos taken between April 19 and May 17

A male and female bluebird

They have been busy building nests and eating black oil sunflower seeds and suet at our feeders.

These pictures were taken in different lightings and at different times of the day.

One of these male birds, or maybe two, have spent the last six weeks flying into windows in front of our house. Somedays it seems to go on all day long.

We have seen and heard this so many times in the last six weeks. It is kind of a knocking/pecking sound on the window. He also makes a mess on the window as you can see.

Some mornings it gets annoying. The other morning one took me off guard by pecking on our front door window at 5:30 am. I was surprised, thinking someone was at the front door. 🙂

At times he sits on the ledge, looking in the window with a confused look. Probably wondering what happened to the other bird.

Ready to make another attack on a window.

I understand that birds do this when they see their reflection in the window and think they have a competitor for their mate.

I also read that they do this when they have a nest close to the house. The tree you see on the right has a bluebird house on it. It is too high for us to look inside, but we see bluebirds coming and going.

That may be the reason why the flying into the windows has gone on for so long this year – because that birdhouse is close to our house. We don’t remember that we have seen a bluebird nest this close to the house.

This was a rainy day. It looks like he is telling me this feeder needs more seeds. Probably so he has energy to fly into our windows off and on during the day. 🙂
