Dedication

                                                   I dedicate this work to the hundreds of persons
                                  who have collected bird data in the UCR during the past century,
                             each furthering our collective understanding of the birdlife of the Region.

Epigraphs

...eventually, all things merge into one, and a river runs through it.  Norman Maclean

It is a wonderful feeling to recognize the unity of complex phenomena that to direct observation
appear to be separate.  Albert Einstein.
