I would like to thank my supervisor, Matthias Laska, for the invaluable advice, guidance and support that he has provided throughout this project. I also thank my co-supervisor, Laura Teresa Hernández Salazar, for always offering to help in any ways needed during my stay in Mexico. Finally, I thank the field station UMA Doña Hilda Ávila de O'Farrill, where I was able to carry out my data collection, and thank you to the Universidad Veracruzana and the Instituto de Neuroetología for a great collaboration on this project.
