Hummingbirds represent one of nature's most interesting paradoxes --they are the tiniest of birds, yet they qualify as some of the toughest and most energetic creatures on the planet. 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.
The smallest of all warm-blooded creatures, hummingbirds live only in the Americas. Many found in North America are seasonal migrants who can live up to 12 years. With nearly 350 different species, these little Americans owe their genetic diversity to their unusual diet of nectar, extreme metabolism and incredible survival instincts.
They are ingenious adaptors and expert aerial predators. Their ability to hover is unique in the avian world. Other evolutionary engineering include the seemingly variety of bills naturally designed to hunt insects and to feed from complicated blossoms with secret nectar chambers. It’s no wonder they are the essential pollinators for over 8000 plant species.
New knowledge gained from scientists currently making great breakthroughs in hummingbird biology makes this a perfect time to focus on these shimmering, flashing jewels of the natural world.
Stunningly beautiful high-definition, high speed footage of hummingbirds in the wild combined with high-tech presentations of their remarkable abilities help us to understand the world of hummingbirds as we never have before.
