With this volume, the well-known author begins a three-part book series that will cover all breeding directions of canary breeding in a compact form. In volume 1, the interesting history of the Canary's development into a domestic bird is examined from partly new aspects. The book contains tried and tested advice on keeping, caring for and breeding canaries in a manner appropriate to their species, as well as on a balanced, largely natural diet. In addition to an introduction to the anatomy of birds, embryonic development and feather structure, the volume also deals with compactly compiled advice on the treatment of diseases and parasite infestations.

This part of the book is rounded off with tips on breeding and training the song canaries.
The second volume of the book series describes in a compact form the colour canaries and the fascinating breeding of carduelid hybrids. The author gives an overview of the history of genetics and the mechanisms of plumage colouration. The latest scientific findings are included.

What is it to be scientific? Is there such a thing as scientific method? And if so, how might such methods be justified? Robert Nola and Howard Sankey seek to provide answers to these fundamental questions in their exploration of the major recent theories of scientific method. Although for many scientists their understanding of method is something they just pick up in the course of being trained, Nola and Sankey argue that it is possible to be explicit about what this tacit understanding of method is, rather than leave it as some unfathomable mystery. They robustly defend the idea that there is such a thing as scientific method and show how this might be legitimated. This book begins with th...
