Droll Yankee Flipper
Battery-operated squirrel-proof feeder
With a weight-sensitive, motorized perch that spins off squirrels, this bird feeder is top-ranked in reviews not only for entertainment value but for effectiveness with gray squirrels. Durable with a tight-fitting metal cap and 3.3-quart capacity, this feeder comes with a rechargeable battery and charger. The interior design keeps seed flowing to four ports. On the downside, reviewers say it doesn't deter red squirrels, and if you don't keep the battery charged, it won't do much for gray squirrels either. We also read a few reports that rain can get into the seed ports.
