This is a comprehensive and up-to-date field guide to the birds of Southern Africa, featuring more than 4000 newly commissioned images. Intended to aid birders in identifying and distinguishing birds in one of the world's richest birding areas, the book depicts over 900 species, resulting in the most comprehensively illustrated field guide ever produced for Southern Africa. Although the region contains less than three percent of the world's land area, more than ten percent of the world's bird species breed here--more than in the whole of the United States and Canada combined. The Guide is devoted to identification features of the different species, sexes, and ages of Southern African birds as well as to their calls and habitat preferences. Both text and plates emphasize the separation of potentially confusing species and identify features which assist in differentiation. Illustrations include as many different plumages of each species as possible to further assist in identification. Special attention has been paid in the illustrations to plumage variations of age, sex, and season and there are numerous depictions of birds in flight, especially where these pictures can aid the birder. The informative text, written by eminent ornithologists, is fully integrated with the color plates to facilitate use in the field. The species accounts emphasize the essential characteristics of each bird, and distribution maps are included for each species. This guide is not only an unparalleled reference, but is a superb visual record of the rich variety of Southern Africa's birdlife.

* What are the consequences of fostering for children, their carers and their birth families? * What are the best ways of recruiting, retaining and supporting foster carers? * What are the most important elements of a successful placement? * Can foster care offer a permanent alternative to care at home? Fostering Now brings together authoritative research on foster care in the UK. It provides a succinct overview of a wide range of research projects and highlights the main implications for policymakers and all professionals involved in the fostering process. Drawing on the varied experiences and views of foster children, social workers, foster carers and parents, this book looks at how placement outcomes are influenced by factors such as foster carers' parenting styles, contact with the child's own parents, and the child's gender, ethnicity, age and physical and emotional health. Other important areas examined include care given by relatives, the effects of foster care on education, and what happens to foster children when they return home. Fostering Now identifies the most significant challenges currently faced by foster care and draws out the key messages for policy and practice. It offers important insights into the state of foster care today, and suggests how it can be improved in future. This book is essential reading for social workers, policy makers, academics and foster carers.

How can we determine success in foster placements? Based on exhaustive research, the authors discuss the primary concerns in foster placement planning, considering the high frequency of placement breakdowns, their impact on the child's behaviour and school performance, and the challenges this places on foster families. The specific needs of the foster child are given close attention in determining a pathway to success. By monitoring and describing the individual characteristics of the child within the context of the placement, the authors are able to reveal what types of supports are most beneficial. The implications for this research are considerable. Social workers are given new methods of assessing the needs of foster children which emphasise the process of care and not just the outcome. Policy makers are provided with rich qualitative accounts with which to increase and strengthen the success of foster placements. This is essential reading for social workers, policy makers and foster families.

First published in 1993, Sasol Birds of Southern Africa is one of the best-selling field guides on the African continent. This fourth edition has been rewritten and greatly improved, ensuring it remains the region’s most comprehensively illustrated and trusted field guide. In this fourth edition: species accounts have been rewritten and now include group introductions; plates have been newly designed for ease of use and comparison; more than 380 new improved illustrations replace earlier ones; illustrations have simplified labels, pinpointing key differentiating features; distribution maps have been updated, showing the relative abundance of a species in the region, and also indicating resident or migrant status. Other features include calendar bars that show species’ occurrence and breeding periods, a section on ‘how to use this book’, as well as sonograms depicting the calls of difficult-to-distinguish birds that have distinctive calls.

Foster care, which can include both long- and short-term placements, is the most common way in which local authorities look after other people's children. Examining the problems and the positive experiences of those providing care, Foster Carers is essential reading for social work professionals, academics and foster carers themselves. Through questionnaire responses from over a thousand foster carers across seven different local authorities, the authors highlight the importance of identifying and fulfilling appropriate kinds of care; the need to recruit and retain carers; and, finally, examin.
