Excuse me sir, but did you just tap on the window? It sounded like you tapped, does that mean there’s peanuts out here? Can I has some? Two years ago, when I first started throwing peanuts out back for the squirrels, they figured it out immediately. The cardinals took a few months, and the sparrows took a full year. The grackles figured it out in two days, incredibly intelligent those grackles.
