From Wikipedia:
Hummingbirds are among the smallest of birds, and include the smallest extant bird species, the Bee Hummingbirds. They can hover in mid-air by rapidly flapping their wings 12-90 times per second (depending on the species). They can also fly backwards, and are the only group of birds able to do so. Their English name derives from the characteristic hum made by their rapid wing beats. They can fly at speeds exceeding 15 m/s (54 km/h, 34 mi/h)

"The Giant Hummingbird's wings beat at 8–10 beats per second, the wings of medium-sized hummingbirds beat about 20–25 beats per second and the smallest can reach 100 beats per second during courtship displays."

#2 Agree - just fantastic beautiful - and see how the wings work creating lift during the forward and back stroke. Looks very elegant - extremely adapted shoulderjoints and muscles...

it would have been nice to see it once in realtime, but i suppose this would have happened in a blink of an eye anyway
#6 i learned some time back that birds use their breast musles to flap.. and Hummingbirds got small wings and big breast.
