Awesome and big thanks! - i did put a bunch of duct tape squares on one of the panes yesterday. Still going, but it may be that he has simply moved to a different pane. I will evaluate and remit.Birder here.
Breeding season for resident birds is just starting. Think Northern Cardinal, both local chickadees and Tufted Titmouse etc.
Early migration is too, think Eastern Phoebe, Palm Warbler etc.
When a bird exhibits this behavior, it sees itself in the reflection and thinks there is a rival on his territory.
So a dirty window will prevent a reflection. Also put a temporary sticker or two on the window where he is pecking.
To all you guys, please feel free to send bird questions.
