The world’s Smallest Bird, Weighing Only Two Grams
The bee hummingbird is a beautiful marvelous bird that weighs just over two grams. This bird has been named the smallest bird in the world. It is slightly larger than a bee, hence the name Bee Hummingbird. One egg is about the size of a coffee bean and is found only in Cuba.
It feeds on flower sap and small insects, and in flight it looks like a flying insect. According to experts, the reason for its short size is a condition called ‘island dwarfism’ or island dwarfism. Evolutionarily, the animals on an island face a shortage of food and resources, and over millions of years, they gradually become smaller than other species. This way of avoiding complete extinction can be seen in many animals.
Along with the B. hummingbird, there are also double-sized hummingbirds on the Cuban islands. Similarly, many islands have some small and some large hummingbirds, but the B. hummingbird is the smallest.
The variety of plants on the Cuban islands is the reason for its survival, where there are countless species of insects and flower sap is abundant. That is why it does not suffer from malnutrition. Surprisingly, its tiny organs produce a lot of energy. It also has a high metabolic rate and body temperature. That’s why it can fly at speeds of 25 to 30 miles per hour. It needs a rich diet to survive and needs the juice of 1,500 flowers a day.
Even after eating innumerable mosquitoes and drinking flower juice all day long, this bird cannot maintain its body temperature at night. For this, he runs a special kind of winter dream-like condition in ‘Torpor’ so that energy is consumed less and physical strength is not dispersed.
The male of the hummingbird is handsome but small in size, while the female is small in size. Its nest is no bigger than a golf ball. Due to its feathery wings, it is easily eaten by large birds, spiders and other animals.
The maximum lifespan of a Bee hummingbird is noted to be seven years, and its survival is threatened by climate change.
