   Biography

After receiving a "Diplom" in Mathematics (equivalent to MSc) from the Technical University Karlsruhe, Germany in 1981, I undertook studies in structural engineering at the ETH Zόrich, Switzerland, and subsequently worked there at the Institute for Bridge Design until 1984. Later I had my own business in structural engineering until 1997 when I migrated to Australia with my family. There I was able to concentrate entirely on birds and ornithology, interests that I had so far pursued worldwide as a hobby. While conducting birding tours (until 2010) throughout Australia I became familiar with the remote interior of the continent. Soon I developed a strong interest in the rare and poorly known Grey Falcon, a species that had not previously been subject of an autecological study. Since 2014 I conduct the Grey Falcon study as a PhD student at the University of Queensland, Australia.
