Dr Robert E. Simmons
Rob is a behavioural ecologist, conservation biologist and ornithologist specialising in the ecology of raptorial birds, cats and giraffe. His studies have taken him from the UK to Canada, and Sweden to Africa with his main interests being mating systems of harriers, sibling aggression in eagles, reproductive constraints in subtropical species, the evolution of giraffe, the impact of cats and climate change effects on birds. He moved from Windhoek in 2003 where he was part of the Biodiversity Programme for 14 years, specialising on the conservation of endemic, montane and wetland birds in Namibia. He now lives in Cape Town drawn here by black harriers, black eagles, whales and a stimulating research environment. His academic research on harrier ecology span both hemispheres and resulted in the publication of his first book Harriers of the World: their behaviour and ecology, published by Oxford University Press. He is continuing that work in collaboration with Fitz students with a 15-yr genetic, ecological and satellite-tagging study of endemic black harriers. A film of this work was completed in 2011 (The Secret Life of the Circler - HomeBrew Films). Rob's studies of climate change effects on birds include vultures and fynbos-endemics (with Phoebe Barnard) and he has also initiated the African continents' first studies of the impact of domestic cats on the biodiversity in greater Cape Town. Following his long-term studies of threatened birds in Namibia he has written his second book on Namibia's threatened birds, Birds to Watch in Namibia: red, rare and endemic species, with Chris Brown, and Jessica Kemper due for publication in 2015. He watches buzzards, whales and cats in between environmental impact assessments, from Constantia with his partner Marlei and two daughters.
