Birds useful and birds harmful

A practical guide for anyone who works the land, this volume surveys the many ways birds affect farms, orchards and gardens. Drawing on extensive field data from Hungary, it explains which species help control pests, spread seeds or pollinate crops, and which can damage grain, fruits or young trees. Clear, illustrated identification keys let even casual observers spot the differences in plumage and shape without needing a scientific background.

Written with both the seasoned farmer and the curious naturalist in mind, the book balances detailed observations with easy‑to‑read explanations. It highlights the seasonal habits of familiar birds—from sparrows and swallows to owls and raptors—showing how their roles change through the year. The author also offers sensible advice on protecting beneficial species while managing those that cause trouble, making it a valuable reference for sustainable countryside stewardship.
