Our back yard feeders are attracting all kinds of birds as well as a large rabbit and a couple of pesky squirrels. When I have something left over - like the inedible kernels in a bag of popcorn - I toss it on the ground in the hopes the rodents will focus on that. Well, it worked for a little while - this guy couldn't get enough, it seemed - but not long afterward, there he was, back on the bird feeder.
