Taschenbuch. Condición: Neu. Neuware - 'The Practical Value of Birds' is a comprehensive study of the economic and ecological significance of avian species. This work explores the complex relationship between birds and the environment, focusing particularly on their role in controlling insect populations and aiding agriculture.The book is divided into two main parts: a general discussion of bird physiology, feeding habits, and the balance of nature, followed by a systematic analysis of specific bird orders and families. The author provides detailed data on the dietary habits of various species, illustrating how their presence can be both beneficial and, in some cases, detrimental to human industry. By synthesizing vast amounts of field data and scientific observations, the work advocates for the protection and conservation of bird life based on their tangible contributions to the human economy and the stability of natural ecosystems.'The Practical Value of Birds' remains a foundational text for those interested in ornithology, agricultural science, and the history of conservation efforts. It serves as an essential resource for understanding the intrinsic and practical worth of the world's bird populations and the scientific methods used to evaluate their impact on the environment.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
