Hummingbirds are most beautiful birds endowed with dazzling colors and hues. But these birds seem to be consigned to the extreme life because at the end of the day, they are so exhausted that it is not sure whether or not they will live to see the another day. Their humming near the flowers in which they insert their specialized beaks to suck the nectar while steadying themselves by constantly flapping their wings, seems like a fluid motion poetry. It is sight to behold. They can fly forward and backward, up and down manoeuvrings come as easily to them.

So they are not the ordinary birds but take the definition of extraordinary to a whole new level. They are the smallest warm-blooded creatures on the planet, but they are also among the fastest. They measure on the average 4-5 centimeters. They can  With wings that beat up to 200 times every second, they are among nature’s most accomplished athletes, the only birds able to hover, fly backwards, and even upside down.

Hummingbird metabolisms are set in permanent overdrive, requiring them to consume more than half their body weight in nectar every day. Some researchers say that nectar consumption for providing energy to fuel the furious activity during the day time, may be equal to their own weights. Since nectar provides them only sugars for energy, they have to supplement it with insects for getting proteins and other nutrients.

To survive the night, they fluff up their feathers and adjust their body thermostats, and reduce their body temperatures by half and reduce their heart rate from 600 beats per minute to a mere 36 to save the energy for survival  and begin their struggle for life next morning.

Due to their small size and dizzying speeds, human beings know only the crude facets of their sizes. PBS has sponsored a study to peer closely into their lives. By using state of the art technology and high definiton cameras, they have been able to delve deep into the private lives of hummingbirds. With  cameras able to capture over 500 images a second, the hummingbirds’ magical world can finally be seen and appreciated. Amazing footage shows these little powerhouses are far more than delicate nectar gatherers — they are also deadly predators. And watch as the birds display their elaborate mating rituals, showing off with nose dives that subject them to over ten G’s of force — enough to cause an experienced fighter pilot to black out!

These tiny marvels dazzle and delight bird watchers all over the world, and NATURE reveals their stunning abilities as they have never been seen before.
