Updating details for old book

[Jess]

I have a photo that could be added for this cover. Additionally I have the summary for this book that could be added:

Beaverhills Lake, some 65 kilometres southeast of Edmonton, Alberta, has long been known as one of the major staging areas in western North America for wildfowl and wading birds bound to and from the western Arctic.
Over the years it has attracted many well known ornithologists who visited its shores to collect or observe the teeming flocks that gathered on its muds and grassy flats. Among them was Dr. William Rowan, for many years Chairman of the Zoology Department of the University of Alberta, who pioneered a field in avian biology now known as photoperiodism in birds.
For almost 40 years Rowan collected at the lake and kept extensive notes on the birds and his own activities regarding them. It is on these notes that much of this book is based.
Since the early 1950's, the Edmonton Bird Club has made several trips annually to the Lake. Its members, too, have contributed much to the knowledge of the avifauna of the lake and have added several new species to the list of the birds of Beaverhills. Many of their notes are also incorporated in this book. 
Although birds form a large part of the subject matter of this book it is not just a bird book. Rather it is a story of the people and their association with the avifauna of what still remains a most fascinating place.
