Acknowledgments RECUPERA 2020 project partially funded Miguel Ferrer for this study. We
are grateful to the Doñana Natural Processes Monitoring Team, especially José Luis Arroyo and
Fernando Ibáñez, and also Luis García, Héctor Garrido, José Luis del Valle, Rubén Rodríguez, and
Alfredo Chico. The authors want also to thank to Consejería de Medio Ambiente de la Junta de
Andalucía for the funding of the Long-Term Monitoring Program of Doñana Natural Space and the
annual census of Doñana breeding birds. Thanks to the owners of Veta La Palma for their cooperation and help in accessing the colonies.
