~~~~~~~~~~~~~~~~~

"It is far and away the best book ever written about birds … the best 'all-round' book we have ever seen; the one that best answers the purposes of all readers; the one which conveys the most information per thousand ems; the one which is freest from misstatements of any sort; the one which is most cautious and conservative in expression of opinions where opinions may reasonably differ; the one which is the most keenly critical, yet most eminently just in rendering adverse decisions...."

—From an extended review in The Auk.
