National Poetry Month: Featured reading by Austin Smith

almanac smith jacketAustin Smith’s debut collection, Almanac, is a lyrical and narrative meditation on the loss of small family farms. Most of the poems are personal, set in the rural Midwest where Smith grew up. Though they are geographically specific, the greater themes such as death and perseverance are as universal as they are disquieting.

The collection is also a meditation on apprenticeship. Smith, the son of a poet, reflects on the responsibility of a young poet to mourn what is vanishing.

Listen to Austin Smith’s reading of his poem, “Coach Chance”.

austin smithAustin Smith was born in the rural Midwest. Most recently, he was a Wallace Stegner Fellow in fiction at Stanford University. He has written a collection of poems entitled Almanac: Poems.

An interview with Tonio Andrade, author of Gunpowder Age

To what degree do times of peace impact military power and precision? In his new book, Gunpowder Age, Tonio Andrade shows how throughout Chinese history, powerful enemies have inspired periods of intense military innovation and technological advancement. Andrade recently took the time to answer some questions about his book, China’s fascinating military past, and its potential emergence a modern day superpower.

Gunpowder AgeChina is fast becoming a military superpower now. Your book claims to find a “pattern to the Chinese military past.” How do current events fit into this pattern?

TA: China under its current leader, Xi Jinping, has become increasingly assertive, for example by building artificial islands in the South China Sea to buttress China’s claims to jurisdiction over the vast majority of the sea. These claims are disputed by many nations, including the USA, and analysts wonder whether China would really go to war to defend them. Some believe that it inevitably will, because rising powers tend to use their muscle to overturn the status quo, while existing powers tend to defend the status quo. Others, however, argue that China has traditionally maintained a defensive perspective on military power and is typically uninterested in waging aggressive wars. If we look at China’s deep history, however, we find numerous occasions when China used its overwhelming military power for aggressive warfare. Intriguingly, many of those occasions occurred at times analogous to today, when the dynasty in question had consolidated power after a difficult period, often spanning generations, and had reached a position of overwhelming regional power.

So you believe that China will likely use military force to assert itself over surrounding areas?

TA: China will use the most effective means to achieve its ends and maintain its security. Xi Jinping has said that war between the USA and China would be disastrous at present for both countries, and I believe China will try to avoid direct confrontation. Typically, in the past, when China has waged aggressive war, its power was overwhelming (or perceived as such) vis-à-vis its enemies. Today, however, China is in a situation less like the early Ming Dynasty (1368–1644) or Qing Dynasty (1644–1911), in which China was far more powerful than any surrounding country, than like the Song Dynasty (960-1279), which faced enemies that matched it in power, or, indeed, outmatched it. The Song fought many wars, but usually these were defensive wars, not wars of expansion.

You argue that when China faces powerful enemies it tends to be stronger and more innovative, and when it is overwhelmingly powerful its military power tends to atrophy. Is its current military power due to the fact that China faces an unusually strong rival in the USA?

TA: China’s military past seems to follow distinct patterns. We have to be careful to distinguish what we mean by “China,” however, because much Chinese warfare has typically been against other Chinese, and/or against other states occupying parts of what is today China. In any case, for much of its history, China has shuddered between periods of intense warfare and periods of relative peace, and during times of frequent warfare it has tended to have state-of-the-art military technology, techniques, and organization. During periods of extended peace, on the other hand, it has tended to fall behind, simply because it had fewer reasons to invest in military innovation. China’s current military power has been stimulated by more than a century of war and geopolitical insecurity, and there’s no doubt that China’s current military innovation and expansion is stimulated by competition with powerful rivals, most importantly the USA.

What were other periods of strength and weakness in China’s history?

TA: Probably the most significant period of relative weakness was the nineteenth century, when China found itself spectacularly vulnerable to western power, as first made clear in its humiliating loss to Great Britain in the Opium War (1839-42). Many Westerners explained China’s stunning weakness at that time by recourse to its cultural conservatism, to what they felt was a deep resistance to new ways or foreign ideas. These sorts of ideas are still very much around. But in fact, China’s resistance to innovation was a pretty short-lived phenomenon, and it can be explained by looking at the incidence of warfare experienced by China. Starting in the mid-eighteenth century, China’s Qing Dynasty had a position of such overwhelming strength and authority both within and beyond its borders that for nearly a century its inhabitants faced fewer wars (both external and internal) than ever before in the historical records. China was, in a sense, too strong for its own good, because this overwhelming power removed the stimulus for military improvement. Meanwhile, the British and their neighbors were fighting huge wars and innovating furiously. When China and Britain went to war in 1839, the British had military capacities that were far beyond those of China: Congreve rockets; light and powerful cannons; light, mobile howitzers; percussion cap muskets; explosive shells of unprecedented precision; and artillery tables that allowed the calculation of trajectories with extraordinary accuracy.

After the Opium War, why did it take so long for China to catch up with the west?

TA: Actually, Chinese officials, military and civil, carried out quite a bit of innovation right after the Opium War, studying Western guns, steamships, and sailing ships, and that innovation sped up during the intense military conflagrations that beset China starting in the 1850s. Many historians (I am one) now believe that from a technical standpoint the Qing were catching up quite effectively by the late 1860s and early 1870s. Indeed, it seems likely that up to that point their modernization attempts were even more effective than than those of Japan. But by the late 1880s, the trajectory changed, with Japan’s innovations becoming more effective. The reason is not technological or cultural but political. Japan’s old regime fell in 1867, replaced by a newer, centralized government that modernized its political structures. The Qing, however, held on, and its political structures failed to adapt. In fact, it’s a curious coincidence of history that the Qing and Japan’s old regime lasted exactly the same number of years. It’s just that the Japanese regime, which was founded first, also fell first. Japan had a clean slate and could sweep away old, unproductive aspects of its old regime. China couldn’t, so the Qing, although it effectively added new military structures – huge factories, innovative new armies, powerful new navies – couldn’t get rid of old ones, and so it was burdened and inflexible.

Your book starts with the invention of gunpowder and traces the evolution of the gun in the period 900-1280 or so, but one of the great questions of world history is why, if the Chinese invented the gun, they didn’t use it as effectively as the West?

TA: Most people know next to nothing about early gunpowder weapons, and I was no different when I started writing the book. In fact, even experts in China’s military history knew very little about early guns until recently, but what we’re learning is causing us to question some deep narratives in world history. Guns were tremendously important in China, used highly effectively. By the mid- to late-1300s, some 10% or so of Chinese infantry soldiers were armed with guns, meaning there were probably more gunners in Chinese armies than there were troops of all kinds in Western Europe (excluding Iberia). By the mid-1400s, the proportion of gunners in China had reached 30% or so of infantry forces, a level Europeans didn’t reach until the mid-1500s. And Chinese soldiers used guns more effectively as well, deploying them in advanced and highly-disciplined formations by the mid-1300s. Similar disciplinary techniques and formations didn’t spread in Europe until the 1500s. So you can see that Chinese gunners were highly effective, more effective than westerners during this period. This early history of Chinese gunnery is almost entirely unknown, but it is a key part of world history.

That’s very interesting, but of course Europeans did eventually get better at gunpowder technology. When and why did this happen?

TA: During the early gunpowder Age, from around 900 or so (when the first gunpowder weapons were used in battle) to around 1450, East Asians led the world in gunpowder warfare. Starting around 1450, however, Europeans pulled ahead. Why? I believe the answer has to do with levels of warfare. From 1450 or so, the Ming dynasty entered into a period of relatively low warfare, which contrasted with the previous century of intense warfare. This period of relative peace (emphasis on the word relative) in China contrasted with a period of tremendous warfare in Europe. So Europeans, fighting frequently, developed new types of guns – longer, thinner, lighter, and more accurate – whereas Chinese guncraft stagnated. This period lasted only a short time, however. By the early 1500s, Chinese were innovating furiously again, and the period from 1550 to 1700 or so was a time of tremendous warfare in China. China stayed caught up with the west from a military perspective – ahead in certain respects, behind in others – until the mid-1700s when, as I said before, it entered into a great period of relative peace (again, emphasis on the word relative), during which it fell behind, a situation that lasted until the Opium War.

Carelli transforms the most ordinary of images, such as a walk home from work or a game of Frisbee in a winter park.

An exclusive reading from Carnations:

Anthony Carelli’s poems have appeared in various magazines including The New Yorker, Columbia, and Commonweal, and on various websites including, AGNI online, and Memorious. His first book, Carnations (Princeton University Press, 2011) was a finalist for the 2011 Levis Reading Prize. Recipient of a Hodder fellowship and a Whiting Writers’ Award, he currently lives in Brooklyn, New York and teaches at New York University.

Bird Fact Friday – Is the Mute Swan silent?

From page 284 of Waterfowl of North America, Europe & Asia:

The Mute Swan is not mute at all. Its most frequent call is a wee-rrrr or wiingrr-iew with a high-pitched second syllable. It will also make an in-rrr sound accompanied with strong hissing in aggression. In flight, the wings produce a whistling sound, typical of the species.

Even celebrities misquote Albert Einstein

Calaprice_QuotableEinstein_pb_cvrAlice Calaprice is the editor of The Ultimate Quotable Einstein, a tome mentioned time and again in the media because famous folks continue to attribute words to Einstein that, realistically, he never actually said. Presidential candidates, reality stars, and more have used social media make erroneous references to Einstein’s words, perhaps hoping to give their own a bit more credibility. From the Grapevine recently compiled the most recent misquotes of Albert Einstein by public figures and demonstrated how easy it is to use The Ultimate Quotable Einstein to refute those citations:

Albert Einstein was a wise man, even outside the science laboratory. He has inspired painters, young students and comic book creators. Even budding romantics take advice from him.

So it should come as no surprise, then, that so many people today quote Einstein. Or, to be more precise, misquote Einstein.

“I believe they quote Einstein because of his iconic image as a genius,” Alice Calaprice, an Einstein expert, tells From The Grapevine. “Who would know better and be a better authority than the alleged smartest person in the world?”

Nicholas J. Higham: The Top 10 Algorithms in Applied Mathematics


From “Computational Science” by David E. Keyes in Princeton Companion to Applied Mathematics

In the January/February 2000 issue of Computing in Science and Engineering, Jack Dongarra and Francis Sullivan chose the “10
algorithms with the greatest influence on the development and practice of science and engineering in the 20th century” and presented a group of articles on them that they had commissioned and edited. (A SIAM News article by Barry Cipra gives a summary for anyone who does not have access to the original articles). This top ten list has attracted a lot of interest.

Sixteen years later, I though it would be interesting to produce such a list in a different way and see how it compares with the original top ten. My unscientific—but well defined— way of doing so is to determine which algorithms have the most page locators in the index of The Princeton Companion to Applied Mathematics (PCAM). This is a flawed measure for several reasons. First, the book focuses on applied mathematics, so some algorithms included in the original list may be outside its scope, though the book takes a broad view of the subject and includes many articles about applications and about topics on the interface with other areas. Second, the content is selective and the book does not attempt to cover all of applied mathematics. Third, the number of page locators is not necessarily a good measure of importance. However, the index was prepared by a professional indexer, so it should reflect the content of the book fairly objectively.

A problem facing anyone who compiles such a list is to define what is meant by “algorithm”. Where does one draw the line between an algorithm and a technique? For a simple example, is putting a rational function in partial fraction form an algorithm? In compiling the following list I have erred on the side of inclusion. This top ten list is in decreasing order of the number of page locators.

  1. Newton and quasi-Newton methods
  2. Matrix factorizations (LU, Cholesky, QR)
  3. Singular value decomposition, QR and QZ algorithms
  4. Monte-Carlo methods
  5. Fast Fourier transform
  6. Krylov subspace methods (conjugate gradients, Lanczos, GMRES,
  7. JPEG
  8. PageRank
  9. Simplex algorithm
  10. Kalman filter

Note that JPEG (1992) and PageRank (1998) were youngsters in 2000, but all the other algorithms date back at least to the 1960s.

By comparison, the 2000 list is, in chronological order (no other ordering was given)

  • Metropolis algorithm for Monte Carlo
  • Simplex method for linear programming
  • Krylov subspace iteration methods
  • The decompositional approach to matrix computations
  • The Fortran optimizing compiler
  • QR algorithm for computing eigenvalues
  • Quicksort algorithm for sorting
  • Fast Fourier transform
  • Integer relation detection
  • Fast multipole method

The two lists agree in 7 of their entries. The differences are:

PCAM list 2000 list
Newton and quasi-Newton methods The Fortran Optimizing Compiler
Jpeg Quicksort algorithm for sorting
PageRank Integer relation detection
Kalman filter Fast multipole method

Of those in the right-hand column, Fortran is in the index of PCAM and would have made the list, but so would C, MATLAB, etc., and I draw the line at including languages and compilers; the fast multipole method nearly made the PCAM table; and quicksort and integer relation detection both have one page locator in the PCAM index.

There is a remarkable agreement between the two lists! Dongarra and Sullivan say they knew that “whatever we came up with in the end, it would be controversial”. Their top ten has certainly stimulated some debate, but I don’t think it has been too controversial. This comparison suggests that Dongarra and Sullivan did a pretty good job, and one that has stood the test of time well.

Finally, I point readers to a talk Who invented the great numerical algorithms? by Nick Trefethen for a historical perspective on algorithms, including most of those mentioned above.

Attract some more Silent Sparks in your life

With firefly season drawing ever closer, we thought it would be a good time to share some tips for making your yard friendlier to these bright bugs. In addition to a wealth of information on fireflies, Silent Sparks by Sara Lewis includes a handy field guide for the firefly-enthusiast. Use these to fill your yard with twinkling lights during the summer evenings ahead.

Fireflies love a yard with spots of longer grass because when grass is longer, the soil holds more moisture. Fireflies need moist places to lay their eggs. If you leave some leaf litter and other natural debris in your yard, baby fireflies will have a place to grow.

When thinking about outdoor light, err on the side of less. Light pollution confuses fireflies during their courtship rituals. Use Dark-Sky compliant, shielded fixtures. Use bulbs with the lowest wattage that will meet your needs. Turn off outdoor lights when you’re not using them, or put them on timers or motion sensors.

Finally, limit your use of pesticides to horticultural oils or insecticidal bacteria that will target specific pests. Consider using organic products, and only apply them to target specific problems as opposed to routinely.

If you follow this expert advice, you’ll be on your way to a sparkling summer! While you’re at it, enter to win your own copy of Silent Sparks.

5 Myths About Sustainability

On Earth Day and everyday we all need to focus on ways to be more environmentally conscious and responsible. In Pursuing Sustainability: A Guide to the Science and Practice, Pamela Matson, William C. Clark, and Krister Andersson draw on the most up-to-date science to provide a handy guide that links knowledge to action. In the process, they debunk commonly held misconceptions about sustainability. The first step in affecting positive change is awareness:

1. Sustainability challenges are largely a problem of consumption.
In meeting the challenges posed by implementing sustainable practices, production and consumption should be viewed as parts of an integrated system. Demand may drive production, but production can influence consumption by creating a demand where there was none previously. (Pg. 16).

2. As we move toward more sustainable practices, precedence should be given to the environment; humans should be considered as negative pressures that put ecosystems at risk.
To meet the goals of sustainable development, there needs to be an integrated appreciation and understanding of the social-environmental systems that we are operating in or any solutions will be unbalanced and fall apart over the long-term (Pg. 53).

3. Better policies and technologies are all that is needed to meet the environmental challenges ahead.
The complexity of social-environmental systems means that we cannot always predict the consequences of new technologies or policies. The pursuit of sustainability has to be an adaptive process in which we try the best possible solutions, moniter the results, and make adjustments as needed (Pg. 64).

4. GDP (Gross Domestic Product) and GNI (Gross National Income) are useful metrics when considering sustainability.
Both of these measures do not take important elements into account. First, they measure flows (what is happening now) rather than stocks or assets (what’s left to draw on in the future). They also fail to recognize and integrate the social and environmental as well as the economic determinants of well-being. To achieve an accurate sense of how we are doing in regard to sustainability, other measures and indicators that are more inclusive and broad-ranging are needed (Pg. 76).

5. Implementing sustainable practices means sacrificing profits.
Not necessarily. When taking into account social-environmental systems, sustainable solutions can actually save money. For examples of sustainability success stories that aided in, rather than hindering, economic goals, see Chapter 6 of Pursuing Sustainability.

As we work to meet the challenges posed by climate change and environmental vulnerability, it is important to educate ourselves so that we can arrive at solutions that will work over the long term. This Earth Day, Pamela Matson, William C. Clark, and Krister Andersson’s book is necessary reading.

Justin E. H. Smith on six types of philosophers

Smith jacketThe Natural Philosopher, the Sage, the Gadfly, the Ascetic, the Mandarin, and the Courtier. What would the global history of philosophy look like if it were told as a series of job descriptions—ones that might have been used to fill the position of philosopher at different times and places over the past 2,500 years? The Philosopher: A History in Six Types by Justin E. H. Smith does just that, providing a new way of looking at the history of philosophy. Why six types? Are some types superior to others? Recently, Smith took the time to answer these questions and more about his latest book.

This book doesn’t have a conventional structure or approach. In addition to straightforward scholarly exposition, it also contains autobiographical elements, as well as what appear to be fictional excursuses, written from the perspective of invented historical figures who represent different philosophical types. What are the reasons for this experimental approach?

JS: When I began speaking with my editor at Princeton University Press, what intrigued him most were some reflections of mine on the relationship between the activity of a philosopher and the practical need we all have to earn money and pay the bills. I had recently moved to Paris, was having trouble making ends meet with my modest French university salary, and so had begun experimenting with some ‘freelance’ philosophical dialogues with people willing to pay—mostly Anglo tourists who were looking to experience the frisson of sitting in a Parisian café and talking about love and death and stuff just like Sartre and De Beauvoir. So when I began writing, that personal experience served as the point of departure for reflecting on the long history of the problematic relationship between money and philosophy—after all, one of the most common foundation myths of the tradition is that it began when Socrates refused remuneration, thus liberating whatever it is we’re doing qua philosophers from whatever it is the Sophists had been doing. This approach then sort of expanded to other parts of the book: launching into an investigation of some aspect of the definition of philosophy by revealing something about my own personal engagement with it.

As for the fictional elements, I suppose this is just an irrepressible symptom of the sort of writing I’ve come to believe can best get across what I’m trying to do philosophically. I’m with Margaret Cavendish, who explicitly lays out at the beginning of her delirious 1666 novel, Blazing World, how it is that fantasy can be harnessed and utilized for the exploration of philosophical questions in ways for which the faculty of reason alone might be less ideally suited. I faced some resistance to these portions of the book from some readers of drafts. They wanted me to more clearly mark off and explain what I was doing in them, somewhat as Martha Nussbaum does when she introduces a fictional figure in one of her books to guide as through the exposition of arguments that follow. But I didn’t want my characters to serve simply as didactic aides. I wanted rather for the work to be, at least in part, a work of fiction, a product, like Cavendish’s, of the literary imagination.

Is this book philosophy, or is it about philosophy?

JS: I don’t know that there can really be a valid distinction here. By the same token, I’ve never understood what people mean when they talk about ‘metaphilosophy’. We’re all just trying to come to a clearer understanding of the nature of this activity we’re engaged in, in order, in part, to better engage in it. Philosophy is peculiar in that a great deal of effort is expended, by those who profess to practice it, in seeking to determine where its boundaries are, and what falls outside of them. This is a problem sedimentologists, say, don’t have, and one might easily suspect that philosophy is essentially constituted by this activity, that there’s not much left over to do once philosophers have stopped trying to determine what philosophy is not. I think my approach, the transregional and wide-focused historical survey of the very different ways people we think of as philosophers have themselves conceived what they were doing, helps to establish this point: ‘philosophy’ is said in many ways, to paraphrase Aristotle. I’m sure some critics who have some stake in portraying philosophy as essentially thus rather than so, or vice versa, will be quick to say that this book is ‘not philosophy’. But I think I can survive that, and in fact I think they’ll be helping to support my thesis.

Why six types? Is this list exhaustive or arbitrary?

JS: I make it very clear in the book that there has been no transcendental deduction of all possible types of philosopher, or anything like that. My approach is more like the one Kant accused Aristotle of taking in his elaboration of the ten categories: his listing of them continued until he grew tired. I also make clear that what we usually see when we look at actual philosophers is hybrids of two or more of the types, or different dimensions of the types becoming apparent at different moments in their work. The point of thinking in terms of types is to help reveal the degree to which the expectations placed on a person occupying the social role of the philosopher will determine in part the range of questions or problems that philosopher considers worthy of attention. I think of types as social categories, and for this reason certain social circumstances need to obtain in order for a given type of philosopher to make an appearance. Is an amateur observer of the way snails copulate in Central Park in 2015 a philosopher? No, but someone who was doing the same thing in the Jardin des Plantes in 1665 probably was.

You seem to be more sympathetic to some types than to others. Why?

JS: My training as a scholar, and so to speak my spiritual home base, is in the 17th century, which I see as a brief period of tremendous openness, of liberality and of true love of knowledge, inserted in the middle of what has generally been, philosophically speaking, a long, dark history of tedious scholasticism, provincialism, and submission to authority. Not coincidentally, this is also the period in which most of the philosophical action was going on outside of universities.

While I didn’t mean to structure things in this way when I began writing, as it turned out the chapters, each of which focuses on a particular type, move from my most to my least favorite. The first chapter is on what I call the ‘Curiosa’ (or, masculine, ‘Curiosus’), and the fictional personnage is inspired by none other than Margaret Cavendish. She represents the intellectual virtue that I believe is most lacking in university-based philosophy since at least the moment, sometime around the end of the 18th century, when the natural sciences broke off from philosophy and ‘natural philosophy’ ceased to be a vital and central concern of philosophers. My least favorite figure is the Courtier, whose fictional representative is based loosely on Jan Sten, the Soviet philosopher who was called in to tutor Stalin on Hegel and dialectical materialism and whatever other profound things the dictator was having trouble understanding, and who was eventually purged in the Moscow show trials. Serves that groveling worm right, we’re inclined to say at our safe distance, but the truth is many of us are doing something somewhat similar when we bend ourselves to the reigning ideology of market-driven university research, and pretend to ourselves and others that that’s still philosophy.

You draw on many sources that are not traditionally considered philosophy in the narrow sense. What is the purpose of this?

JS: I just don’t know how one could possibly coherently define the corpus of texts that deserve to be included in, as it were, the imaginary library of the history of philosophy. Recently (too recently to be included in the book) I’ve been thinking a great deal about the philosophical problem of the concept of ‘world’, as it developed in the 17th century, and the way in which this development is central for our understanding of the metaphysics of possibility, counterfactuals, one of Kant’s three transcendental Ideas, and so on. I’ve learned a great deal about the history of this concept from the work, in French, of Édouard Mehl. One thing I’ve come to appreciate is that this concept simply cannot be adequately understood without reading early modern novels, particularly the ones we might call ‘proto-science fiction’, such as Cyrano de Bergerac’s Les états et empires de la Lune. Am I supposed to exclude that just because it’s not a treatise? But then I will fail to adequately understand the philosophical problem that interests me, and that would be bad.

Often we are willing to pay attention to things that canonical philosophers say that are, quite frankly, no less fantastical than 17th-century lunar fantasy novels, simply because they are already categorized as canonical philosophers and therefore, we presume, everything they say is of interest. So Leibniz says that every drop of water in a pond is a world full of beings, and that is poetic and wonderful, but is it any more worthy of our attention as philosophers than when, say, Walt Whitman finds that he incorporates “gneiss, coal, long-threaded moss”? Both capture something profound about nature and our place in it. Whitman says it better, in my view, and there’s no reason not to pay attention to it, as philosophers, on the grounds that Whitman didn’t also come up with the principle of sufficient reason or the infinitesimal calculus.

In the end you describe the work as ‘aporetic’? Does this indicate a failure?

JS: No, it’s philosophy’s fault.

Bird Fact Friday – How do hawks fly such great distances?

From page 7 of Hawks from Every Angle:

Several factors influence the migratory pathways of raptors, including geography. Mountainous sites are famous for attracting concentrations of migrating hawks, in part because as wind strikes a ridge it is deflected upward, providing birds with a current of air—or updraft—along the ridge for more energy-efficient means of travel. Raptors can travel along these updrafts for miles, covering great distances with little to no effort.
Hawks from Every Angle: How to Identify Raptors In Flight
Jerry Liguori
Foreword by David A. Sibley

hawksIdentifying hawks in flight is a tricky business. Across North America, tens of thousands of people gather every spring and fall at more than one thousand known hawk migration sites—from New Jersey’s Cape May to California’s Golden Gate. Yet, as many discover, a standard field guide, with its emphasis on plumage, is often of little help in identifying those raptors soaring, gliding, or flapping far, far away.

Hawks from Every Angle takes hawk identification to new heights. It offers a fresh approach that literally looks at the birds from every angle, compares and contrasts deceptively similar species, and provides the pictures (and words) needed for identification in the field. Jerry Liguori pinpoints innovative, field-tested identification traits for each species from the various angles that they are seen.

Featuring 339 striking color photos on 68 color plates and 32 black & white photos, Hawks from Every Angle is unique in presenting a host of meticulously crafted pictures for each of the 19 species it covers in detail—the species most common to migration sites throughout the United States and Canada. All aspects of raptor identification are discussed, including plumage, shape, and flight style traits.

For all birders who follow hawk migration and have found themselves wondering if the raptor in the sky matches the one in the guide, Hawks from Every Angle—distilling an expert’s years of experience for the first time into a comprehensive array of truly useful photos and other pointers for each species—is quite simply a must.
