One hummingbird can visit as many as two hundred jewelweed flowers in fifteen minutes! Do these grow in your neighborhood? Keep your eyes open. (Dig deeper into what scientists have discovered about this amazing partnership >.) As these travelers fly south each day, hunt for food, and keep warm each night, they quickly use up fuel. So each morning — and early evening after a day of flying — they feed up to replenish energy. A wildflower called spotted jewelweed blooms like crazy during the rubythroat's fall migration. (It's also called touch-me-not because its seed pods easily burst open.) Scientists think its nectar is critical for hummer survival. And the flowers rely on rubythroats, too! The blossoms are shaped just right to make a hummingbird the perfect pollinator as it goes bloom to bloom in search of nectar. Hummers need plants they can depend on throughout their long journeys south. Just look at the routes they travel . . .
