So I put out a bird feeder to attract birds like the second shot to my back yard. But then the squirrel mafia moved in took it over.... and I was tempted to not restock it. But I did anyway, and t my surprise, the birds brought in the big guns. So as it turns out.... put out bird feeder to attract birds -> which attracted squirrels which chased away the birds -> which attracted in the big guy... and it became bird feeder again. The squirrel presence is decidedly smaller now. And all kinds of birds have returned.
