The Robins, like all birds, are getting ready to make babies and you have probably either witnessed this first hand or have heard about it, Robins attacking your windows. What is happening is that the Robin sees a reflection of itself and thinks it is a competitor and so he has to fight it. This can prove to be quite dangerous for them and so we recommend that you put some kind of a decal on the window that will cover the bottom 6″ of glass so they won’t be able to see their reflection anymore. This is a behavior that only last during breeding season but it is a good idea whether you feed birds or not to protect the birds from all windows throughout the year.
