Anatomy: The biggest hummingbird is the Giant Hummingbird of South America; it weighs 20 grams. The smallest hummingbird (and also the smallest bird) is the Bee Hummingbird, which is about the size of a bee!

Most hummingbird's feet and legs are so small that they cannot walk or even hop; hummingbirds mostly use their legs and feet for perching (but the toes and claws are very long, and are used for perching). Hummingbirds are almost helpless on the ground.

Diet: Hummingbirds sip sweet nectar from flowers and eat some tiny bugs. They use their long tongue to lap up nectar.

Nest and Eggs: Hummingbirds make their tiny nests from lichens, spider webs, and plant down (fluffy seed coverings).

Predators: Many animals prey upon hummingbirds, including many other birds, like orioles, roadrunners, hawks, and flycatchers. Hummingbirds can also die when they are caught in spider webs.
