Biography

After receiving, in 1981, a "Diplom" (equivalent to MSc) in Mathematics from the Technical University Karlsruhe, Germany, I undertook studies in structural engineering at the ETH Zürich, Switzerland, and subsequently worked there at the Institute for Bridge Design. 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 a mayor study. In 2018 I received a PhD from the University of Queensland, Australia, for my work on this species, and it seems that, long ago, this study has become a lifetime project.

Research Interests

Aspects of natural and sexual selection and, therewith, competition (in animals).

All aspects of the ecology and biology of the Australian endemic Grey Falcon.
I will be very grateful for observational reports of Grey Falcons, Australia-wide.
