Squirrel proof feeder effective against red and gray squirrels.
When a squirrel climbs onto the feeder, its weight forces the shroud down, closing access to the seed ports. All squirrels and many large birds are foiled but not harmed in any way.
Seed Tube Ventilation System permits humidity and warm air to escape through waterproof vents at the top of the feeder, while being replaced with fresh air entering ports and openings on the bottom.
Can be easily converted into a clinging feeder by removing the perches -- helps deter large perching birds such as Grackles and Doves.
Holds 1.4 quarts or 1.3 pounds. Two year factory warranty.
