Why does a bird keep flying into the window

Both robins and cardinals are well known for this type of behavior but it can occur with any bird. This would seem to be a case of a simple misperception and accident. By reflecting foliage or sky, they look like inviting places to fly into.
They will keep flying and end up slamming into a window. This would appear to be a different phenomenon whereby the bird is choosing to fly into the window for whatever odd reason. Cardinals are highly territorial and defend their nesting area vigorously from other male cardinals.

In this example, the bird sits on a nearby branch flies into the window, leaves or returns to the branch and repeats it again.

This breaks the reflection and other birds interrupt the birds battles with himself. Sometimes a bird may be flying and not know that a window is there. The theory here is that the mesh will reduce the reflection on the windows, so birds will be less likely to think they are flying into whatever is reflected in the window. Post a hawk silhouette outside a window. Hawks prey on birds, so their images will keep birds from flying towards your window. For birds, glass windows are worse than invisible. However there are widespread reports of birds compulsively knocking into the same window repeatedly over days or weeks.
