The Droll Yankees 15 in. Black Squirrel Guard is a creative way to keep squirrels away from your bird feeder. This durable plastic dome with a black topper, shields your bird feeder from squirrels and other garden pests. Suspended on a brass rod, it features a safety lock for hanging your bird feeder. You can adjust the dome's height on the rod as well as its distance from the feeder. A beneficial backyard addition, the dome also protects the feeder from rain, keeping bird feed dry and fresh.The Droll Yankees StoryWhat began as two New England historians, Alan Bemis and Peter Kilham, recording stories, would eventually set the stage for today's beloved bird feeder company, known for making ""The World's Best Bird Feeders."" Why ""droll""? That came from a story by Balzac, and after an experiment with plastic tubing resulted in a frenzy of feathered friends, founder Peter Kilham knew he had something special on his hands. Still located in Connecticut, still proudly made in the USA, the Droll Yankees story lives on - and when you order one of their bird feeders, you'll understand.
