520 _a"Birds Useful and Birds Harmful" by Ottó Herman and J. A. Owen is a combination of scientific publication and practical handbook written in the early 20th century. The book aims to assess the impact of various bird species on agriculture, categorizing them as either beneficial or detrimental to farmers and landowners. It serves as a guide to help people understand the ecological roles birds play, especially in the context of pest control and crop maintenance. The opening of the work sets the stage for a discussion on the economic value of birds, particularly in Hungary, where studies have highlighted their impact on agriculture. It introduces the background of ornithological research and stresses the need for knowledge about bird species, providing insight into both their helpful and harmful attributes. The authors emphasize that these evaluations of birds' usefulness are often subjective and influenced by changes in agricultural practices and environmental conditions. The preface also hints at the overarching themes of protection and rational management of bird populations in agriculture, illustrating the crucial relationship between humans and avian species.
