Has anyone experienced aggressive Cardinals attacking the mirrors of your vehicles? We have a male cardinal, or perhaps several male cardinals, that attack our mirrors! The cardinals actually caused damage to the mirrors so we now cover the mirrors with t-shirts.
They also attack one specific window of the house. It sounds like it will bust the window! I have trimmed back the bushes near that window to try to deter the birds but that hasn't helped.
We love the wild birds that visit our yard. We get several different kinds from woodpeckers to blue jays to hawks, and of course the cardinals. We toss them the seed our domestic indoor birds don't consume. We have a white face cockateil and a rescued mourning dove. Our indoors birds are also aggressive, that is, when they hear a bag of chips being opened, lol.
