You might be thinking that such an equation does not exist or that its formulation is impossible because the biological world is too complex. You would be wrong on both counts. Such an equation does exist and even more remarkable is that it works. Why then is this equation not known to ornithologists world-wide? That, caro lettore, is partly the subject of this book. The man who created the equation, the late Bert Murray, was for most of his career almost entirely ignored by ornithologists, ecologists, and evolutionary theoreticians.
