Hummingbirds : Now a model for micropumps too!

For many years now, scientists have been studying the hummingbird for its flying abilities. Their acrobatic flight is a great model for aeronautical engineers to develop air-crafts for the the future. While everybody concentrated on the wing action, dynamics of the air flow below and over them and the structural differences between humming birds and other fliers to figure out what makes these birds such special fliers, there was something that we had wrongly presumed many years ago, waiting to be discovered about these wonderful birds.  Since the year 1833, we have been assuming that humming birds feed themselves using capillary action . This means, that bird dips its beak into the flower nectar and waits for nectar to slow rise along its longish beak, much like what happens when you sip a cola with a straw, except that you are actually using your mouth to sip in the cola but the humming bird simply waits for the nectar to reach its mouth.  There are two issues with thi

Consuming their weight in nectar everyday, its amazing to watch these dainty little bird go about their business. Here's a video released by Deep Look a new video series created by KQED San Fransisco, that takes a closer look at how these birds do their thing.
