A Naturalist in the Gran Chaco


Book Description

Sir John Graham Kerr (1869-1957) was a Scottish zoologist and politician, well known for his work in relation to the embryology of lungfishes. Originally published in 1950, this book provides an account of Kerr's travels and discoveries within the Gran Chaco region of South America. The text is divided into two main parts: the first discusses the Pilcomayo Expedition of 1889-91, providing detailed information on the 'Natokoi or Toba Indians', together with their natural environment; the second gives an account of the 1896-7 Lepidosiren Expedition, mainly focusing on Kerr's observations of the South American lungfish. Numerous illustrative figures are also incorporated, including photographs, drawings and maps. This book will be of value to anyone with an interest in the Gran Chaco region, anthropology, zoology and the history of science.

The Herons Handbook


Book Description

Everything you ever wanted to know about the world's herons. This book on herons and bitterns is an authoritative summary of what is currently known about this diverse and fascinating worldwide family of wading birds. It is the result of extensive studies carried out over many years by its distinguished authors on both sides of the Atlantic. The plumages, feeding and breeding behaviour, and ecology of each of the recognised species is illustrated in full-colour with paintings meticulously researched by Robert Gilman and Peter Hayman. A distribution map, based on the latest available information, also shows the range of each species. Because of the widening interest in wading birds, considerable attention is paid to identification in the field. Four identification plates, especially prepared by Robert Gillmor, show all the plumages in each stage of every species and race, of white herons and egrets. This information - invaluable for ornithologists and birdwatchers - has never before been brought together in one volume. References to all the relevant literature on herons and bitterns is included for those who want to make a deeper study of these birds, and the authors have contributed their own considerable experiences gained in the field. The definitive handbook on herons, this book will not only provide the basis for future research and conservation but will also be a source of interest and enjoyment for both birdwatchers and ornithologists.
