Kaytee energy treat bar food is both bird food and feeder all in one for a convenient, time-saving option. This treat bar is coated with a vegetable-based fat that provides high energy to birds. This bar supports the energy that birds need to migrate, build nests and otherwise survive in the wild. This bar’s ready-hang feature means you don’t need a separate feeder. It makes for less mess, since there’s no loose feed for your feathered friends to push out of the feeder. This feeder cuts down on the mess and waste. Since birds spend more time pecking at and eating the seed, you’ll have more time to bird watch.
