Played a game of Trivial Pursuit, got a question going: How fast does a Woodpecker peck?
The answer said 2000 km/h (If you're running on miles, do the math yourself :).
Googled a bit and alot of information stated that a woodpecker can peck 15-20 times a second, and if the distance is about 14cm a peck that makes the 2000 km/h.
Another piece of information said a woodpecker will be able to peck continuously for upto one hour.
Giving these facts my question is, would a woodpecker be able to create enough updraft by pecking to fly without using it's wings?
