They flap their wings at an amazing speed.....cant remember the exact number but i thought it was like a thousand or something.....I better google it now.
I just looked on WikiAnswers and they say that they can flap anywhere from 40-80 times a second.....during courtship they can flap up to 200 times a second. So now you know!!!
Good thing i didnt bet the bank on my thousand something guess!!!!!!!
Thank you April :))
Good thing !! but still that is remarkable that their wings beat that fast.. and their nest are only the size of a walnut. I'm forever looking for them as they love this trumpet vine.. can not find them ??
