Feeding birds by way of ice

A few weeks ago,we had small amount of snow and ice. We also did not have any sand or ice melt. Son Mike and his crew were making repairs on our house. Mike used bird seed to give some traction. It worked pretty well.
Last Monday, we had more ice, so I tossed more bird seed on the ramp and driveway. The ensuing warmth and rain washed away the ice, leaving the seeds. Birds large and small are taking care of the rest.
