Indoor Meeting - Tim Birkhead - Birds Eggs - The most perfect thing

Timothy Robert Birkhead  is a British ornithologist. He has been Professor of Behaviour and Evolution at the University of Sheffield since 1976.

Birkhead has combined his enthusiasm for research with a passion for undergraduate teaching. He has taught courses on ecology, evolution, statistics, birds, behavioural ecology, animal behaviour and the history and philosophy of science. His teaching has been recognised by four awards, including a National Teaching Fellowship in 2017.

His recent research is on the adaptive significance of egg shape in birds, including the common guillemot whose pyriform egg has long been thought to allow it to either spin-like- a-top or roll-in-an-arc to prevent it rolling off the cliff ledge. However, there is no evidence for either of these ideas. Instead, Birkhead and colleagues have identified the main advantage of a pyriform shape: stability. The pyriform shape makes the egg inherently more stable, especially on the sloping surfaces on which guillemots commonly breed.
