For maximum protection against squirrels and comfort for your favorite birds, try the Perky-Pet Squirrel-Be-Gone Max Bird Feeder. This outdoor bird feeder includes our patented Flexports, which offer 5-in-1 benefits for optimal feeding and bird safety. The unique design is 4X more shake-resistant than standard ports, resulting in less seed waste. The design also allows birds to feed at an optimal position outside of the port, offering better visibility so they feel safer and stay longer. Each feeding station features a ladder-style perch to accommodate a wide variety of bird sizes.This squirrel proof bird feeder boasts multiple great features for defense against squirrels. The weight-activated perch system supports birds but not squirrels; when squirrels try to access the perches, the ports close off. The new and improved Sure-Lock cap prevents squirrels from lifting the lid, and the metal frame discourages chewing around the ports. For 100% bird feeder squirrel proof placement, hang the feeder with at least 18 inches of clearance on all sides, ensuring squirrels can’t reach it. Ideal for wild bird feeders, this is perfect for those looking for squirrel proof bird feeders for outside. Try these innovative bird feeders for outdoors hanging and enjoy seeing birds thrive
