How It works? Our Technology Openings in the bottom section of the feeder (shroud) align with seed ports, providing birds access to the seed. When a squirrel climbs onto the feeder, its weight automatically forces the shroud down, closing the seed ports. Squirrels and large birds are foiled but not harmed in any way. The Closing Mechanism Use the feeder with the factory setting before making any adjustments. To increase the adjustment setting, rotate the transparent cartridge clockwise. The red line will move down from the previous setting. This increases the weight required to close access to the seed. To decrease the adjustment setting, turn the cartridge counter clockwise. The red line will move up from the previous setting. This decreases the weight required to close access to the seed.
