Expert in bird behaviour Professor Tim Birkhead explains everything you wanted to know about eggs – which end of an egg is laid first, why are the shapes different, why do some contain two yolks and why do the shell patterns vary?

Birkhead explains the science behind the miraculous construction of an egg – from the curiously pointed eggs of the guillemot that are so variable in pattern and colour that no two are the same, to the eggs of hens, cuckoos and many others.

Birkhead is a professor of animal behaviour and the history of science at the University of Sheffield who has travelled the world to understand the lives of birds. He is author of Bird Sense, which sold 40,000 copies across the world and was shortlisted for the Royal Society Winton Prize for Science Books. Other books include Promiscuity, Great Auk Islands, The Cambridge Encyclopaedia of Birds, which won the McColvin medal, The Red Canary, which won the Consul Cremer Prize, and The Wisdom of Birds.
