This award winning bird feeder is effective against Red and Gray Squirrels, as well as Grackles, Starlings, Doves, etc.
It is dishwasher safe and buil to last.
How it works:
Openings in the bottom section of the feeder (shroud) align with the 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.
