Petra's diploma studies focused on raptor research and conservation biology. Her PhD thesis at the University of Vienna, Austria was entitled 'Costs and benefits in the settlement decisions of the Eurasian Kestrel (Falco tinnunculus)' and was a collaboration between the Department of Integrative Zoology, the bird collection at the Natural History Museum, Vienna and the Section of Ecology at the University of Turku, Finland. The study investigated whether city dwelling raptors such as kestrels are attracted to breed in the city centre by favourable conditions, such as the ready availability of suitable nest sites or high levels of potential prey, or are pushed out of rural areas by unfavourable conditions there. By means of an experimental approach, Petra was further able to substantiate the use of public information in settlement decisions, thus broadening her expertise in the field of behavioural ecology.
After research in urban ecology and in remote areas in northern Europe, in 2014 Petra migrated south and joined the FitzPatrick Institute as a PostDoctoral Fellow in the Raptor Research group supervised by Dr Arjun Amar. The project aims to understand the establishment of urban raptor populations. On the Cape Peninsula, urban breeding Peregrine Falcons (Falco peregrinus minor) and Black Sparrowhawks (Accipiter melanoleucus) have been monitored since their colonisation. Petra will analyse that comprehensive data set to address factors underlying the expansion of both urban raptor populations.
