The Auk

The Gyrfalcon
reviewed by Thomas J. Cade



Friends --

When a book review of a major book on a charasmatic raptor species includes 
a statement such as:
"To summarize, this is a rather unfortunate book", and the reviewer is a 
world expert on the species written about, one has to wonder how such a book 
could be published as written, particularly by a major university press.  
This question alone makes reading this book review not only interesting, but 
important to all raptorphiles, all ornithologists and those who rely on 
published science as a means to an end for conservation, personal 
understanding of species' and their natural history, and those concerned 
about negative trends in the publication of works on natural history 
science.

As background, when I heard a couple of years ago that a major new book on 
the gyrfalcon was in preparation, I became excited and knew that I would 
obtain the book.  I would have been more excited if the book was being 
written by Dr. Tom Cade himself, because I consider Dr. Cade to be the 
preeminent expert on falcons of the world, with vast personal knowledge by 
Dr. Cade of gyrfalcons.  Instead, the book was authored by senior author 
Eugene Potapov with assistance from Richard Sale, who I know relatively 
little about and have sparse knowledge of their qualifications to write a 
major book on this species.   But I also trusted that the peer review 
process would pretty much assure that the book would be scientifically 
accurate, if not groundbreaking, and that the information in it would be 
reliable as a future reference in the significant details.  I bought the 
book and looked briefly at it, but have not read it in detail.  Then, fairly 
recently, I learned that Dr. Cade had written a review of the book for The 
Auk, and I could not wait to read Dr. Cade's review in order to see his 
appraisal of the new book I had purchased.

Regarding Dr. Tom Cade, if he were a bird, I think he would probably be a 
gyrfalcon.  He is a scholar, a field man, a great writer, holds enclopedic 
knowledge of science within his specialty, and apparently is a bit feisty, 
which is especially welcome in a person of his stature and achievement.  If 
I were to be "chewed out" or criticized by someone, I would much rather it 
come from the best, a real world-class authority like Tom Cade than by 
someone of low stature, so I believe the authors of this book should take 
this review as professional, constructive criticism and not personally.

In a nutshell, this review provides the expert opinion that the authors of 
the book under review were not major researchers of the species they wrote 
about, and thus their most valuable contribution by publication of the book 
was their review of the literature on the gyrfalcon, and especially so 
because the authors accessed Russian language literature and other 
non-English literature, often from sources that would be considered obscure 
for the typical English-language reader of this book.  But, when the authors 
attempted to perform original analysis of aspects of gyrfalcon natural 
history, biology, systematics, etc., the reviewer felt that their analyses 
and arguments were weak and unpersuasive.

Additionally, according to the reviewer, "the book was not well edited and 
contains many errors".
All sorts of errors were detected by the reviewer and even quantified:  "I 
found 260 errors and confusions in 280 pages of text and references".

The review was not all negative, though.  The reviewer described his own 
personal excitement at reading natural history accounts provided by the 
authors of this species, particularly in the Russian and Siberian range 
where the authors had access to literature accounts and perhaps personal 
experience that were obviously of great interest to the reviewer.   The 
reviewer also expressed support for a position taken by the authors 
regarding the appropriate scientific name or the species, which all agreed 
should be changed from F. rusticolus to F. gyrfalco.

A large part of the review dealt with efforts by the authors to analyze 
colors and color patterns of gyrfalcons and their significance.  While the 
reviewer seemed to display an open mind towards the arguments and 
assessments of the authors, Dr. Cade concluded that the result of the 
authors analyses were more confusion, not less.  Arguments that suggest 
novel explanations for such phenomena need to follow a rigorous  logic that 
provides facts, addresses contradictions, explains controversies, and 
reaches appropriate conclusions.  Arguments that provide opinions with some 
facts but lack of appropriate rigor lose their power and can result in 
confusion, not clarification.  I believe this is the major problem that Dr. 
Cade dwelt on regarding this discussion.  Since the discussion of colors and 
patterns formed a major part of this book, and were so flawed for the 
reasons described above, and were typical of overall flaws in the book, it 
was no surprise that the reviewer concluded by saying that "the inquiring 
reader is likely to be disappointed by lack of synthesis and summary of the 
many details presented, and the often difficult text must be read with 
care."

But the question emerges, how could a book with these profound weaknesses be 
published, particularly in a situation where its publication authomatically 
places it in a role as a likely major reference to the natural history and 
biology of this species?  What is wrong (if anything) with the peer review 
process, including the editing process which was specifically commented on 
by the reviewer?

I will here state my own personal opinion based on repeated observation.  It 
appears to me that peer review has often followed a process in which a 
certain profile of science is looked for in which formulaic science is 
sought for publication for its own sake.  Data and data accuracy are often a 
secondary concern.  Even study design seems to be of less concern to peer 
reviewers prior to publication as long as the scientific process seems based 
on formula, such as statistical analysis, genetic analysis, or specifically 
PCA (principal component analysis) as used by the authors of this book in 
reference to plumages of gyrfalcons.    By comparison, recently a friend of 
mine told me in private conversation that his recent publication in a major 
ornithological journal of a paper on diet habits of a different falcon 
species were published, according to the editor of the journal in question, 
not because of the uniqueness of the data or relevance of the data, but 
because the editor was specifically interested in the specifics of the 
statistical analysis.  The data in too many cases is less important than the 
process of analyzing it.  In my view, when process takes priority over fact 
or truth, then false conclusions are more likely to be produced and accepted 
and published.  Once published, bad information tends to be repeated and 
relied on by those unfamiliar with good information and a cycle of error is 
likely to be set in place.


Thanks to the book review editor of The Auk for asking Dr. Tom Cade to write 
this review!  Thanks to Dr. Cade for explaining in some detail his reasons 
for his disappointment.  As owner of this book, I will be better able to 
approach it and understand its weaknesses while enjoying it strengths since 
I have this input from Dr. Cade.

And I will take this opportunity to notify readers of this posting public 
that Dr. Cade's seminal work, 'The Falcons of the World" is out of print, 
but well worth owning, and I also believe it would be a great time for an 
update of that book in a new edition.  Much additional research has been 
done worldwide on falcons since the original publication and I hope that Dr. 
Cade would consider revising and updating his important book.
