During most of his career Eduardo has investigated aspects of mating systems, sexual selection and parental investment in birds. His experience with shorebirds started during his MSc thesis when Eduardo studied the Southern Lapwing in Central Brazil. Southern Lapwings are a really interesting shorebird because they exhibit a form of cooperative breeding. Eduardo is currently using mainly comparative methods to address general questions in behavioural ecology. He has been a lecturer in Behavioural Ecology at the Department of Zoology of the Universidade de Brasília since 2015.
