Cristina began her work with birds after falling in love with the blue-footed boobies in Isla Isabel, Mexico. Interested in their behavior, since then she has continued to study seabirds and plovers, studying the developmental long-term consequences of brood’s hierarchies in boobies and the mating behaviour, mating system and social enviroment in plovers. She finished her PhD in the University of Bath in 2016 and she currently works on a project that focuses on the causes that make some species more vulnerable to extinction.
