Mary Heys is of British nationality and was brought up in Africa, Hong Kong, the United Kingdom, Malta and has lived for many years in France. She first discovered her passion for wildlife photography in 1997 after a safari in Kenya, followed the year after by a safari in Botswana.
Encouraged by her father and her friend professional photographer, Roberto Berrettini, she improved and perfected her technique. Since then she has visited parks in many other countries in Africa famous for wildlife, including the Masai Mara in Kenya, Kruger Park in South Africa, Etosha in Namibia, South Luangwa and Liuwa Plains in Zambia, the Serengeti (and other parks) in Northern Tanzania and also the lesser known parks in Southern Tanzania: Selous and Ruaha. She has travelled on safari in the Okavango Delta in Botswana regularly over the last 14 years. Most years she also spends between two and three weeks in wildlife parks in India, in particular Bandhavgarh and Kanha National Parks in Madhya Pradesh. She has thus aquired an ample knowledge of African and Indian wildlife. Her interest in wildlife and conservation is extensive but, as is notable from her photos, her particular interest is in the big cats. She has published in magazines and books in the United Kingdom and the United States. She has lived in Rome for the past 28 years.
