The crystal-clear plastic enables close-up bird observation from any room. The viewing opening is approximately 7 inches and accommodates larger birds such as cardinals. Squirrel-proof design. The window feeder includes cross-rod door stops and removable nutritious trays for easy cleaning and refilling. When mounted on a window, you can place it higher to reduce access by squirrels, with mounting options that suit your setup (including higher placements near branches or other structures). Material and compatibility. Made from crystal-clear plastic for durability and visibility. Designed for window mounting to bring birds into your living space for convenient viewing and enjoyment.
