Tim Birkhead, the Chair of Trustees, is emeritus professor of behaviour and evolution at the University of Sheffield. His research on promiscuity and sperm competition in birds helped to re-shape current understanding of bird mating systems. He is a Fellow of the Royal Society and as well as a passion for research, Tim has been committed to undergraduate teaching and the public understanding of science. His talks (like The Early Birdwatchers) and popular science books have gained widespread recognition: The Wisdom of Birds (2008) won ‘bird book of the year award’ and Bird Sense (2012) and The Most Perfect Thing: Inside (and Outside) a Bird’s Egg (2016) were both short-listed for the Royal Society Popular Science Prize. His most recent book is Birds and Us (2022 Penguin/Viking).
