"David Snow's work is known to the professional ornithologist as an almost unrivalled series of papers on the lives of the birds of the great forests of South Americas. Most, however, of his important publications have appeared in scientific journals, many of which are not easily available to the general public. The Web of Adaptation is an attempt – and a highly successful one – to give the general reader an insight into the lives of birds which differ so greatly from those of our own birds"
