Strictly, it refers to 7—12 species in which the male is glossy black often with white belly and has a curled crest of feathers and a brightly coloured bill ornament; the female, lacking the ornament, is smaller and brownish. Curassows are game birds with delicious flesh. Large examples to nearly cm [40 inches] are the great curassow Crax rubra , from Mexico to Ecuador; the helmeted curassow Pauxi pauxi , of the mountains of Venezuela and Colombia; and the razor-billed curassow C. Southern helmeted curassow Crax unicornis Albert E. Gilbert The chachalacas comprise 11 species and are the smallest and least arboreal members of the family.

The aim of the Alexander Library is to build up a comprehensive collection of literature as a service to ornithologists. The library has always greatly benefited from its close relationship with the BOU. For a number of years, all journals received in exchange for Ibis have been depos- ited in the library, and through the generosity of reviewers, most of the books sent for review.
In return, as a service to readers, this review section of Ibis is organized and edited by Michael G. They are always grateful for offers of further assistance with review- ing, especially with foreign language titles.
Part of the cost of this book review section has been subsidized by Subbuteo Natural History Books. Subbuteo are an international mail-order book company stocking over titles covering all natural and environmental sciences. They can also source titles from around the world. International postage is charged at cost; please contact them for a quote.

The Neotropical curassows and related birds guans and chachalacas , belonging to the family Cracidae, are residents of forests in Central and South America. Several members of the family are rare and threatened. When they go, other wild- life will soon follow.
The original Curassows and Related Birds, an artistic masterpiece with detailed textual treatment of the Cracidae, was co-authored by celebrated ornithologists Jean Delacour and Dean Amadon and first appeared in see Ibis This new edition, 31 years later, includes the original text and illustrations most by A.
Gilbert with a few modifications and additions, including new plates and, most importantly, an update chapter written by Josep del Hoyo, Senior Editor of the Handbook of the Birds of the World, and Anna Motis. The other artists who contributed new plates were J. Lane and the late G. They are also well-known orni- thologists and illustrators of scientific books on birds.
The qualities of the authors and their expertise have made this volume a delight to read, a must for anybody who is seriously involved in the study and management of the Cracidae family. Furthermore, the accessible language, and the quality of its illustrations and figures also make this book attractive for the non-specialist.
The book is divided into the original text from the first edition and the update chapter. Within the original text, there are three parts. The first guides us through general characteristics of members of the Cracidae such as their habitats, morphology, their particular anatomy, differences in reproduction, captive breeding, conservation and related expeditions under- taken by the authors.
The second part describes the eight genera and 44 species of Cracids. A key for identification is provided, which helps to avoid confusion. Furthermore, because the taxonomy could be controversial, additional comments regarding the systematics of some species are also included. In the third part, a generous list of refer- ences is provided. The update chapter complements the information of the first edition, new scientific data from field and aviary research having been added.
For example, there is a description of the downy young of Cracids. It also consid- ers the piping guans of the genus Pipile and lists 50 species. It is good to see the new and contemporaneous information pro- vided in the update chapter. For example, in the White- winged Guan Penelope albipennis account [pp. I was able to testify to the presence of these guans in the wild and the participation of the local com- munity in the conservation of the Tumbesian fauna in Chaparri when I visited the area in There are few typographical errors in the text.
Also, I became confused when I wanted to write the complete citation of this book: was this edition sponsored by the American Museum of Natural History p. It will be especially useful in evaluat- ing data obtained in the field and in providing a full list of references. Although it might be expensive for colleagues working in the Neotropics, I strongly recommend it to anyone with a passionate commitment to the study of guans and curassows. Oscar Gonzalez Bauchinger, U. NY Acad. Before his untimely death in , Eberhard Gwinner, founding director of the Max Planck Institute for Orni- thology at Seewiesen, was, without doubt, one of the most important and innovative ornithologists of the 20th century.
Ebo was known for the pioneering nature of his work and so it is fitting that the published proceedings from two recent European Science Foundation-funded workshops are dedicated to him, as a gesture of thanks for encouraging the organization of two highly successful international workshops.
This workshop sought to address the methodological problems associated with measuring hormone levels in two circumstances: from faecal samples and in egg yolks. The inspiration for this meeting came from the recent interest in combining functional and mechanistic approaches to understanding avian behaviour and evolution. Although highly laudable, this approach has led to some problems owing to ignorance of the basic assumptions underlying endocrine processes and technical procedures, with con- sequences for data acquisition from novel substrates.
The proceedings from this workshop 15 papers should be essential reading for anyone embarking on measuring hormone levels from any substrate other than plasma, as the series of papers outline the underlying problems and approaches that need to be adopted with such data.
While pointing out the problems associated with non-invasive endocrine measures, this volume also demonstrates how useful such measures can be, when analysed appropriately. This is particularly important in situations where invasive sampling is undesirable because of practicalities or welfare concerns, or where it is simply not possible. The second part of this section deals with steroid measurements from avian yolk samples, a highly topical issue, considering the increased interest in maternal effects.
Again, methodological concerns are highlighted. A second meeting was held in January , addressing optimality in avian migration, Are there specific adapta- tions for long-distance migration in birds?

Nigel Hughes "A catalogue of paintings exhibited at the Fine Art Society, London, June , shows 41 colour illustrations of the neotropical bird family Cracidae. Nigel Hughes is the first person to have painted all 50 species of curassows, guans and chachalacas from living specimens, and these paintings show them in their native habitat. An inserted booklet describes the biology, ecology and conservation efforts to save these remarkable birds from extinction. The original work of by Delacour and Amadon included wonderful illustrations by A. This new edition contains all the original drawings and plates as well as stunning new plates by A E Gilbert illustrating the chicks of some of the species, and incorporates the plates from the Handbook of the Birds of the World corresponding to this family.

Helmeted curassow , Pauxi pauxi Linnaeus Temminck Alternatively, all subfamilies except the Penelopinae could be lumped into the Cracinae. As the initial radiation of cracids is not well resolved at present see below , the system used here seems more appropriate. It is also quite probable that entirely extinct subfamilies exist as the fossil record is utterly incomplete. Recent research has analyzed mt and nDNA sequences , morphological , and biogeographical data to study the phylogenetic relationships of cracid birds, namely the relationships among the genera Pereira et al. The traditional groups—chachalacas, guans, and curassows—are verified as distinct clades , but the horned guan represents the sole survivor of a very distinct and ancient lineage. In addition, the molecular data suggest that the Cracidae originated in the Late Cretaceous , but the authors caution that this cannot be more than a hypothesis at present: as the rate of molecular evolution is neither constant over time nor uniform between genera and even species, dating based on molecular information has a very low accuracy over such long timespans and needs to be corroborated by fossil evidence. The fossil record of cracids is limited to a single doubtfully distinct genus of chachalaca, Boreortalis Hawthorn Early Miocene of Florida , USA; may actually be a junior synonym of Ortalis and some species in the modern genus Ortalis , however.
