Droll Yankees' Silhouette feeders hold several different foods and come in window- and wall-mount options. The Window-Mount Songbird Feeder features a songbird and blueberries design, and the black metal bracket is designed to attach to a window with three strong suction cups, the company states. A bird's nest vignette adorns the Wall-Mount Songbird Feeder and shows a mama bird feeding her babies. The black metal bracket attaches to any deck rail, fence or shed with two wood screws (included), according to the manufacturer. Each feeder includes a sturdy, 6-in. clear seed dish that locks into the bracket, holds 2 cups of seed, fruit or mealworms, and includes drainage holes to keep food dry and fresh, the company adds.
