Book Description
One cannot help being struck with wonder at the vivid pink of 10,000 flamingos rising from Lake Nakuru or the glowing red gorget of a ruby-throated hummingbird feeding outside the kitchen window. How birds produce the brilliant and striking coloration of their feathers and other body parts is the focus of this first volume of Bird Coloration. It has been more than 40 years since the mechanisms of color production of birds have been reviewed and synthesized and in those 40 years new pigments have been discovered, new genetic mechanisms have been described, new theories have been developed, and hundreds of new experiments have been conducted. </p>
Geoffrey Hill and Kevin McGraw have assembled the world's leading experts in perception, measurement, and control of bird coloration to contribute to this book. This sumptuously illustrated volume synthesizes more than 1,500 technical papers in this field. The focus is on the three primary mechanisms of color production--melanin pigmentation, carotenoid pigmentation, and structural coloration--but less common as well as newly described mechanisms of color production are also reviewed in detail. The visual perception of birds and the best ways to collect and analyze color data are, for the first time, presented as part of the review of mechanisms of coloration. This book will be essential reading for biologists studying animal coloration, but it will also be treasured by anyone curious about how birds produce and perceive their bold and brilliant color displays. </p>

Hill will definitely become more widely appreciated as time wears on...
The poem's ethical obsession is with pitch, as opposed to tone: the making and upholding, in language, of difficult distinctions as opposed to - so far as it can be held distinct from - the equitable imperative smoothing-over of disputes and differends (the "healing" snake-oil of much contemporary political rhetoric). In illustration of this, as in obedience to it, "Speech! Speech!" bristles with split hairs. The defamatory satirical genius of the poem lies in its outrageous conflations, a wit that works insidiously, like guilt, by association. But its moral animus ("animus is what I home on, even as to pitch" - section 90) is focussed on those parts of speech where one is surprised to see distinctions being made, or remade - surprised that they should (still) be thought or seen to matter. There are many places in the poem where it becomes difficult, important, to ascertain what is being driven at, from what angle (or angles) and with what force. So, in section 57, the speaker beckons: Show you something. Shakespeare's elliptical late syntax renders clear the occlusions, calls us to account... The reader of "Speech! Speech!" is similarly drawn to the places where Hill's elliptical verse indicates, but does not show, unaccounted-for ommissions, exclusions, losses. We are ordered to "[j]udge the distance" between generations, to take the measure of what Hill sees as the abrupt - overnight - pillage and erasure of a common heritage - "common" in a sense to be distinguished from, but not opposed to, that of "demotic". This is arguable, of course, and the poem argues with itself about it, about the meaning of "democracy" and the condescension of "the egalitarian anti-elitist SUN" (a widely-circulated British newspaper, whose language Hill parodies passim). Nevertheless, Hill seems genuinely shocked by the way that English culture has changed over the past fifty years, and is clearly contemptuous of the ability of electronic databases and the "world-surfing quote research / unquote of your average junk maestro" (cheers!) to replace the "forms of understanding, far from despicable, / and furthest now, as they are most despised" he celebrated in "The Triumph of Love" (section CXIX). His argument may be judged reactionary, but it is passionately made. I have found it difficult to receive the verses of "Speech! Speech!" as Hill says they were intended - as praise-songs. What is being praised is presumably the faculty the poem itself aspires to, that of fashioning a language fit for human use out of the "acoustic din" of an indifferent mass culture. Or, rather, what is both praised and petitioned by "Speech! Speech!" is that part of ourselves that might find a use for such a language, that is too proud and attentive to be satisfied with less - that is healthy enough to curse. But sheer celebratory delight (not, for once, miscalled) is achieved only in brief epiphanic flushes, as if by concession: for the most part the dominant, almost ineluctable mood of the poem is one of sadness and anger. "Speech! Speech!" is a poem to spend time with - more time than I have spent so far. Notice is given on the inside sleeve that it is a "tour de force", and I would not dissent from that; however, there is much about it that will not come immediately, and may not come at all until the last measures of one's own reading (such is the messianic hope of interpretation). Off you go, then...
Book Description The last documented sighting of the Ivory-billed Woodpecker--one of the rarest and most intriguing animals in the world--was noted over 50 years ago. Long thought to be extinct, the 2005 announcement of a sighting in Arkansas sparked tremendous enthusiasm and hope that this species could yet be saved. But the subsequent failure of a massive search to relocate Ivorybills in Arkansas made hope for the species' revival short-lived. Here, noted ornithologist Geoffrey Hill tells the story of how he and two of his colleagues stumbled upon what may be a breeding population of Ivory-billed Woodpeckers in the swamps of northern Florida. He relates their laborious attempts to document irrefutable evidence for the existence of this shy, elusive bird following the failure of a much larger research team to definitively prove the bird's existence. Hill tells of his travails both in and out of the vast swamp wilderness, pulling back the curtain to reveal the little-seen political maneuvering that is part of all modern science. He explains how he and his group decided who to exclude or include a

Book Description
This volume brings together poems from four decades of Geoffrey Hill's work.Customer Reviews:
An excellent collection that will take some digestion.......2001-07-04
Not that these poems are easy, not even the ones Hill wrote when he was 19 (like "Genesis", the opening poem of the collection). What they are is challenging, beautiful, thoughtful, at times meditative, at times lyrical, often skeptical, almost always wonderful.
These are poems written for those who love poetry and don't mind if it's hard, who can reread a poem ten times in order to appreciate it, who have the patience to learn to read a real poet. Although this book is only 200+ pages, there is a lifetime (almost!) of reflection contained within it, from the early poems reflecting on art, responsibility, history and war in "For the Unfallen", to the funeral music of "King Log", the beautiful prose poems of "Mercian Hymns", and the deeply religious "Tenebrae".
Give it some time. Don't judge it too quickly. Hill will certainly be remembered as one of the greatest poets of the 20th and early 21st centuries, as one who recognized the heavy responsibility of a poet in our times.
