In the third paragraph, the writer says that because of the increased air speed on the top surface of the wing, there is increased pressure. Unfortunately, if that were true, the opposite of lift would be achieved and the poor birds would plummet to their deaths. Also, according to Bernoulli's principle, as the air's speed increases, the pressure it exerts decreases, which is, in part, how bird wings create lift.
