we have had a robin hurling himself at our windows for several days. It started with seeing his reflection in the front door kick plates, which we then papered over. Then he moved to full size windows in the living room and made a terrible mess. We put screens over the windows. Then he moved to the transom over the deck door. Papered them over and then he moved to the deck door. Please help with any information you might have about this insane behavior.
This is common behavior for male birds staking out their territory. They see another male (themselves!) in a reflection, and try to drive them away. Cardinals and mockingbirds are the usual culprits of this behavior.
Covering glass with paper, pulling the blinds or drapes, or somehow making ihe glass nonreflective works well usually. Decals can help. You seem to have an unusually persistent male.
If there are branches (or other perches) where he sits and sees his reflection, try to prune them off or otherwise move them.
In many cases, after the initial spring territory-staking period, the males calm down and the behavior stops. Maybe they are too busy feeding baby birds.
