Birds are smaller than pennies

With a body weight of only 1.6 to 2 grams, not as heavy as an American coin, bee hummingbirds deserve to hold the "world's lightest bird".

Bee hummingbird

Bee hummingbird (scientific name Mellisuga helenae ) is the smallest bird known in nature, with a length of 5-6cm. Weighing 1.6 to 2g, it is even lighter than US and Canadian coins.

Like other hummingbirds, bees fly very fast and strong. It can stop at a point like a helicopter. The wing beating speed is 80 times / s, so fast that the human eye cannot catch up.

Male bees are usually smaller than females. Once she gives birth, the female lays about 2 eggs. It is mainly distributed in Cuba, in humid subtropical climate, where there is sufficient food and the climate is largely unchanged. Therefore, this species does not have to migrate as far as its 'relatives' .

It likes to live in areas with flowering plants of Solandra grandiflora, a beautiful climbing plant with flowers. However, this species is threatened by the narrow living area, the forest is turned into arable land.
