Tz'unun! Tz'unun! A buzz of wings, a flash of color . . . There’s a very special visitor in Granny’s garden. It’s a hummingbird! And it’s just about to begin its long migration, heading north to its nesting ground. Watch as it spreads joy to all who encounter it along its two-thousand-mile trek. In an engaging text sprinkled with facts, zoologist Nicola Davies introduces readers to this valiant bird, lighter than a nickel, while Jane Ray’s lush, intricate illustrations, accented in gold Pantone, highlight its jewel-like beauty. More details about hummingbirds, along with a bibliography and an index, are available at the end to budding ornithologists.
