Squirrels are a constant source of annoyance to those kind souls trying to care for hungry birds. Most feeders cannot foil squirrels effectively. These feeders are an exception.
The perch is attached to a weight-activated door that closes over the seed ports when anything too heavy arrives for a visit. The adjustable spring mechanism can be set to accommodate various weights, in order to discourage heavy birds such as grackles, while leaving songbirds free to enjoy their dinner. The lid locks shut when in the closed position to keep critters out. A seed-saver baffle reduces seed spilling and waste. Squirrels* get frustrated with this feeder and often give up trying to find a way to dine.
With a powder-coated, galvanized steel body, this durable feeder is available in two versions: a single-sided model that measures 13 1/4" × 10 5/8" × 6 1/4" high and holds 1 1/2 gallons of seed, and a double-sided model that measures 14 1/2" × 12" × 9" high and holds 2 gallons of seed. Either feeder can be hung with the included wire hanger or pole-mounted (hardware included); the double-sided model comes with a 5' pole.
* Effective against black squirrels. Immature red squirrels can sometimes gain access due to their size.
