The three songbirds etched on these colorful glass sun catchers are based on Diane Pierce's illustrations from our bird-watcher's essential volume, National Geographic Complete Birds of North America. This northern cardinal, chipping sparrow, and blue grosbeak brighten any window, especially during winter months when the real things might be a rare sight. Hang on a Christmas tree, or use the included suction-cup hooks to hang on a window. 2 1/2''W x 4 1/2''H.
