The smallest bird in the world is the bee hummingbird, found primarily in Cuba. This tiny bird measures about 2.2 inches (5.5 cm) in length and weighs around 0.07 ounces (1.98 grams). The male bee hummingbird is slightly smaller than the female and is renowned for its iridescent plumage and rapid wing beats, which can reach up to 80 times per second. Bee hummingbirds feed on nectar from flowers, playing a vital role in pollination. Their remarkable flying abilities, including hovering and agile maneuvers, allow them to access food sources that many other birds cannot reach.
