Defying Gravity

tags: , ,

Eastern Gray squirrel, Sciurus carolinensis.

Last but not least was a demonstration of the so-called "gravity assist" method. It was obvious that this required the most skill but was not always as effective as the the other methods. In fact I watched three squirrels drop their Black Walnuts. One retrieved its nut only to drop it again while assuming a second gravity assist posture. Considering the outcomes I am not at all sure that gravity assisted these participants at all but there is no denying the artistry involved in the attempt. Please don't attempt this yourself. Instead I suggest utilizing the standard method. And be sure to use a nutcracker. Bon appetite! (last in a series of three).

Olney, Illinois is famous for white squirrels. In 1943 there were 1000 of the little guys but by the '90s the population remained constant around 200. The town has implemented a rather strict set of laws to protect them.

I have been hit on the head by nuts thrown out of trees by squirrels in Central Park.

There is a gray squirrel at Jet Propulsion Laboratory that drops pine cones -- big ones, unopened and therefore hard and dense -- on people's heads from high trees. I got nailed once, and I've learned my lesson -- Look Up Above!

CRM,

You completely misconstrued the lesson. Look at your feet. The back of your head is a lot tougher than your face!
