Hummingbirds drink nectar, a sweet liquid inside flowers. They are attracted to red, orange, and yellow flowers. When hummingbirds feed, they pollinate flowers. Pollination is the transfer of flower pollen, the male sex cells, from the stamen to the pistil, the organ that bears seeds. This transfer allows seeds to form and new flowers to grow. Hummingbirds pollinate thousands of flowering plants.
Hummingbirds also eat insects. The size of this prey, creature hunted for food, depends on the size of the hummingbird.
