* that study was widely whooped when it came out - but of course both
office buildings and Cats are currently much more widespread than wind
turbines. What we need to understand, in evaluating the ecological
impact of planned turbines, is how many Birds, of which species, would
wind turbines kill for any level of electricity production (i.e.
birds/megawatt), and how much this ratio would be influenced by the
stupid vs intelligent placement of the turbines - e.g.

"[The] two fundamental steps of scientific thought - the conjecture
and refutation of Popper - have little place in the usual conception
of intelligence. If something is to be dismissed as inadequate, it is
surely not Darwin [, whose] works manifest the activity of a mind
seeking for wisdom, a value which conventional philosophy has largely
abandoned." Ghiselen, 1969. Triumph of the Darwinian Method, p 237.
