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.
