This is a very biographyof the ornithologist-field biologist, as well as a good story of the effort to save the Whooping Crane.

Although the book is about a field bilologist, the book really tells in detail the personal efforts and daily activities of those involved in saving the Whooping Crane species.

The book follows Bob Allen across North America as he attempts to pin down every detail on the crane's life style, winter and summer ranges and territory requirements, food supply, predation, migration stop-overs, and anything or everything that could affect the species safety.

The biography covers the entire many decades of this effort thoroughly and I recommend it for following this effort.

A dlightly less complete version, written in the first-person instead of the biographer, is Allen's own story on saving the species, "On the Trail of Vanishing Birds", is at least as exciting, but a little less complete as the story was still unfolding during his time before writing his own book in 1957.

There are very few illustrations in the book but it is a very good biography of Bob Allen. The reader will come away with a great respect for all that the man did for endangered birds when saving vanishing species was a hope and not yet a success on any species.

The author wrote a good biography and included the excitement of Allen's work in the field. ( )
