The smallest bird in the world is the bee hummingbird
The bee hummingbird is a kind of hummingbird and also the smallest warm-blooded animal in the world. Their body length is about 5.6 - 6.5 centimeters, including the length of the beak and tail feathers. The average weight is only 2 grams, lighter than a coin. The egg weighs 0.2 grams, which is about the same as a pea.
Although the bee hummingbird is small in size, their flying skills are extremely superb. They can fly to the left or right, can also fly backward, and can hover in the air. Their beaks are as slender as needles, and their tongues are like a thin line, which is very suitable for feeding on nectar.
The bee hummingbird is mainly distributed in the various islands of Cuba in Central America and is a unique bird of Cuba. Due to the influence of human activities, the tropical and subtropical forests and swamps on which the bee hummingbird lives have been seriously damaged. The population has greatly decreased and it has become an endangered bird, urgently needing human protection.
