PhD (UCT) 2016

Megan is a conservation biologist with HawkWatch International and also an Honorary Research Affiliate with us at the Fitz. Her work focuses on applied research and conservation of raptors, and her publications have ranged from investigating the illegal killing of hen harriers in the UK to describing the flight strategies of eagles in South Africa.

Megan completed her PhD in 2016, co-hosted by the Fitz and the Animal Demography Unit, on the ecology of Verreaux’s Eagles in natural and agriculturally transformed habitats. Her study investigated the differences in breeding productivity, diet and movement ecology of two contrasting populations. Broadly speaking, she found that eagles in the agriculturally transformed study area breed more successfully, have more diverse diets and do not appear to be under higher energetic demand than those in a natural environment.

Following this Megan spent two years as a Post-doctoral Fellow at the Fitz, working closely with Assoc. Prof. Arjun Amar to understand the risk which wind turbines can pose to Verreaux’s Eagles. Using GPS tracking data she built a predictive model which can determine the likelihood of collisions with turbine for this species on a fine spatial scale prior to construction of new wind energy facilities.

Megan also leads our research on understanding the population declines of Marital Eagles in Kruger National Park. This project is a collaboration between the Fitz, HawkWatch International and the Endangered Wildlife Trust.
