乐生活Mellisuga helenae, one of the smallest birds, is endemic to Cuba and Youth Island. They weigh about 1.8 grams and are 5 centimeters long. They are one of the smallest birds in the world.
As the smallest bird in the world, honeybeepers are as big as bees. They are as light as other hummingbirds and have a very strong flying ability. They can stay at the same location like helicopters. It is estimated that they flap their wings 80 times per second, and even the naked eye can not catch up with their speed.
The rainbow and bright feathers of bee-sucking birds make them look like tiny gems (after all, only large bees). However, the rainbow is not easy to see, depending on the perspective to see. Their long pointed beaks can penetrate flowers and eat nectar. Its tongue is also like a long tube, which can sip nectar. When looking for food, their beaks and heads stick to pollen, which can help spread. Within a day, bee-sucking birds can reach 1500 flowers, which is very helpful for plant reproduction.
Female birds use spider webs, bark and lichens to build nests. The diameter of the nest is about 2.5 cm long and cup-shaped. Bird eggs are as big as peas. Females incubate eggs and feed their young separately.
