The sword-billed hummingbird (Ensifera ensifera) is a South American hummingbird with the longest bill to body proportion among birds. It specializes in flowers with long corollas such as Datura, passionflowers and fuchsias. These hummingbirds are a very extreme example of coevolution between pollinators and the plants they pollinate. It's bill is so large that it can not be used in groom so the bird grooms with it's feet. It must hold it's bill at a certain angle to fly and perch. They are also among the largest hummingbirds at 12 grams.
