Dr Gabriel Jamie has just returned from a successful couple of months of fieldwork in Zambia as part of his Leverhulme Early Career Research Fellowship. For this research, Dr Jamie is exploring the evolution of polymorphisms across diverse avian family Cisticolidae which exhibit some of the most complex and diverse eggs of any group of birds in the world.
