Peter Berthold – författare

The question of how birds migrate over enormous distances with apparently minimal guidance continues to excite both professional and amateur ornithologists. Nearly ten years have elapsed since Peter Berthold, a leading researcher in the field, wrote the first edition of this highly readable and fascinating book. During that time the field has advanced by strides, so that this new edition has been extensively revised, expanded, and updated. No other book exists that brings together the vast amount of information that is available on the subject of bird migration, so that the book will be an inspiration to birdwatchers, naturalists, and ornithologists alike.

The reader of this comprehensive presentation benefits from an outstanding overview of all aspects of the fascinating phenomenon of bird migration. The book is written by leading experts from around the world. The text summarizes reviews and discussions of the most recent hypotheses. In doing so, it covers the entire research field from phenomenology through to ecology, physiology, control mechanisms, orientation, evolutionary aspects and conservation measures. It also examines the most modern methodological approaches including, satellite trakcking, molecular techniques or stable isotope investigations and envisages forthcoming developments in the course of global warming.

P. Berthold and E. Gwinnd Bird migration is an intriguing aspect of the living world - so much so that it has been investigated for as long, and as thoroughly, as almost any other natural phenomenon. Aristotle, who can count as the founder of scientific ornithology, paid very close attention to the migrations of the birds he ob­ served, but it was not until the reign of Friedrich II, in the first half of the 13th century, that reliable data began to be obtained. From then on, the data­ base grew rapidly. Systematic studies of bird migration were introduced when the Vogelwarte Rossitten was founded, as the first ornithological­ biological observation station in the world (see first chapter "In Memory of Vogelwarte Rossitten"). This area later received enormous impetus when ex­ perimental research on the subject was begun: the large-scale bird-ringing experiment initiated in Rossitten in 1903 by Johannes Thienemann (who was inspired by the pioneering studies of C. C. M. Mortensen), the experiments on photoperiodicity carried out by William Rowan in the 1920s in Canada and retention and release experiments performed by Thienemann in the 1930s in Rossitten, the first experimental study on the orientation of migratory birds. After the Second World War, migration research, while continuing in the previous areas, also expanded into new directions such as radar ornithology, ecophysiology and hormonal control mechanisms, studies of evolution, ge­ netics, telemetry and others.

Vögel strahlen Schönheit, Anmut und Freiheit aus. Wenn sie verschwinden, werden auch wir verschwinden. Der Vogelkundler Peter Berthold zeigt uns den Weg, dies zu verhindern.Das aufblitzende Blau eines Eisvogels. Das Gelb des Pirols im Blätterdach eines Auwaldes. Ein Schwan vor dunklem Schilf. Auch der Morgenchor in unseren Wäldern oder das Abendlied einer Amsel über den Dächern der Stadt machen uns staunen, so wie die schwebende Möwe im Sturm oder der Adler im Aufwind. Vögel faszinieren uns auf vielfältige Weise. Und sie sind uns ans Herz gewachsen. Doch Vögel sind auch unsere wichtigsten Bioindikatoren. Ihr zunehmendes Verschwinden zeigt uns, dass es um ihren und unseren Lebensraum in diesem Land nicht gut bestellt ist. Denn das Artensterben hat inzwischen alle Gruppen von Tieren und Pflanzen erfasst und macht auch vor dem Menschen nicht Halt. Es wird höchste Zeit, daran etwas zu ändern. Peter Berthold, Deutschlands renommiertester Ornithologe, zeigt uns in seinem faszinierenden Buch die Vielfalt unserer Vogelwelt, aber auch, weshalb sie gefährdet ist und was wir tun können, um sie zu erhalten.
