As I watched over the weekend the epic battles the hummingbirds have for superiority over the feeders or flowers, I was reminded of this post from our beloved Lex.
During the dive, the hummingbirds experienced an acceleration force nearly nine times that of gravity, the highest recorded for any vertebrate undergoing a voluntary aerial manoeuvre, with the exception of jet fighter pilots. At 7g, most pilots experience blackouts.
Of course it would not be a complete Lex post without his snark. Go to the link for further enjoyment.
