The hummingbird may be one of the most well-known birds on earth, yet this colorful acrobat continues to mystify the greatest mathematicians and aeronautical engineers. Just when they think they’ve learned all there is to learn about these birds, they discover more.To read the rest or download the audio version (by my favorite narrator), click on "Hummingbirds—Avian Acrobats of the Americas". Two other items of interest, "Hummingbirds Fly in the Face of Evolution" (which has an interesting video at the bottom) and "Flighty Evolutionary Speculations Taint Hummingbird Taste Study".
Hummers differ greatly from other birds. . . No other creature can match their skills. And man-made craft don’t compare. (What helicopter can cross the Caribbean Sea on a half ounce of fuel?)
