Jonathan's "The Big Cat Man: An Autobiography" (Bradt) was published in August 2016 alongside a large format book of Jonathan and Angela's award-winning photography called "Sacred Nature: Life's Eternal Dance" (HPH) designed by their son David and based around their love affair with the Mara-Serengeti. This won them the Gold Award for Photography in the Independent Book Publishers Awards in 2017. They were the keynote speakers at Wild Shots in South Africa in October 2016, and at the Royal Geographical Society in London in November 2016 and again in October 2019.
