In Pollinators and Plants, Nature’s Perfect Pair, narrator Sir David Attenborough explores the fascinating teamwork — and clever defenses — between plants and pollinators! Monarch butterflies rely on milkweed plants for laying eggs and gathering nectar, but the plant defends itself with a sap that challenges the caterpillars. Meanwhile, the Heliconia plant carefully rations nectar to keep the hummingbird returning, as only this bird’s uniquely shaped beak can pollinate it! This video is excerpted from BBC's Life, a show that explores the remarkable strategies animals and plants use to ensure their survival.
