Droll Yankees Flipper squirrel-proof bird feeder — 5 lb capacity, rechargeable motor

The Droll Yankees Flipper is a battery-powered, weight-activated hanging bird feeder that gently spins off squirrels while leaving birds to feed uninterrupted.

Designed and assembled by Droll Yankees, this outdoor bird feeder pairs a clear, high-capacity polycarbonate tube with a weight-sensitive spinning perch and an enclosed motor to protect seed from persistent squirrels. The 21-inch seed reservoir holds about 5 pounds of mixed seed, so you refill less often while still giving visiting songbirds unobstructed access to four feeding ports. Rechargeable power and a snug metal cap complete a setup focused on durability and humane squirrel deterrence.

How does the Flipper stop squirrels without harming them?

The Flipper uses a weight-triggered perch ring linked to an encased motor. When a squirrel lands on the perch, the motor briefly spins the feeder so the mammal loses its footing and falls away; birds are too light to activate the mechanism. This approach avoids traps, poisons, or shocks and prioritizes animal safety while protecting seed.

• Weight-sensitive perch engages only for heavier animals
• Enclosed motor shields electronics from weather and chewing
• Spinning motion is brief and non-injurious
• Tight metal cap prevents lid-lifting by clever squirrels

How much seed does it hold and how is seed delivered?

The clear polycarbonate tube measures about 21 inches long and holds roughly 5 pounds of seed, making it easy to monitor fill levels at a glance. Inside, a simple baffle and angled interior guide seed toward the four ports so each station stays supplied as birds perch and feed.

• 5 lb capacity reduces refill frequency
• Four feeding ports provide simultaneous access for multiple birds
• Interior funneling maintains consistent seed flow to ports
• Transparent body shows seed level instantly

What power and maintenance does the feeder need?

The Flipper runs on a built-in rechargeable lithium-ion battery and includes a charging system; batteries are replaceable if needed. Routine maintenance is straightforward: charge the battery as recommended, wipe the polycarbonate tube clean, and check the perch ring and cap for wear to keep the mechanism reliable.

• Built-in 11.1 Wh lithium-ion battery, lightweight and long-running
• Encased motor and charger included for protected operation
• Simple cleaning with mild soap and water; avoid harsh solvents
• Replaceable battery and backed motor warranty for peace of mind

Will larger birds like cardinals and woodpeckers be able to feed?

Yes — the perch ring and port spacing accommodate medium and large songbirds without triggering the squirrel-defeating mechanism. The perch is tuned to ignore typical bird weights while delivering seed reliably to cardinals, jays, titmice, and similar visitors.

• Perch design distinguishes bird weight from squirrel weight
• Four stations allow several birds to feed at once
• Sturdy polycarbonate resists cracking from active birds
• Bird-friendly port size fits a range of species

Who is this for? The Droll Yankees Flipper suits homeowners and backyard bird enthusiasts who want a low-maintenance, humane way to reduce seed loss to squirrels while supporting a variety of feeder birds. It’s a good fit for yards where birds are frequent visitors, for people who prefer mechanical deterrents over chemical or lethal methods, and for anyone wanting an easy-to-monitor, high-capacity hanging feeder that blends durability with playful squirrel-proof performance.
