Horsfield H.K. Side lights on birds. An introduction to the study of British bird life
London: Heath Cranton Ltd., 1923. — 266 p.
Birds, like men, may be looked at from many points of view. Admirable text-books exist that tell us of the material side. But there are many aspects of bird life that he outside the textbooks.
The idea of this book is to try to show something of the animating principle of the bird, how it lives, moves, and has its being, how it reacts to the varying conditions of its environment; how its wonderful life expresses itself in its equally wonderful and beautiful form. Not that there is anything new in this, but the scope for new treatment is illimitable, especially in view of the new facts constantly coming to light.
For the most part, the deeper questions relating to bird life — migration and so on — have been dealt with by specialists in spacious volumes not readily accessible to the amiy of young ornithologists who are growing up arormd us. In these cases I have endeavoured to smimiarise the work of the leading authorities: to show so far as my limitations pemait, how our knowledge stands to-day: to give younger readers especially a general view of the subject before they come to grips with the severer technical side.
