In The Swordbill Hummingbird: Overcoming the Competition, narrator Sir David Attenborough visits Ecuador, where over 100 species of hummingbirds compete for limited nectar in flowers. Learn about the swordbill hummingbird, which has a beak longer than its body, and can reach nectar in flowers that other hummingbirds can’t. Though it has an exclusive food supply, the long beak is hard to keep clean and makes it difficult for the bird to preen feathers. This video is excerpted from BBC’s Planet Earth II, a breathtaking documentary series that highlights the natural wonders of our planet.

The article "Hummingbirds: Tiny Birds With Big Abilities" from BBC's Discover Wildlife is a detailed guide to the world of hummingbirds. It explores their unique flight skills, diet, habitats, and how their fast metabolism drives their daily routines. With over 350 species, these birds face threats from predators and habitat loss, but they continue to amaze scientists and birdwatchers alike.
