About the Author(s)

Fernando Medrano has had a lifelong interest in wildlife and entered into the world of birding at the age of 18 when he started his career as an engineer at Universidad de Chile. Here, he became involved in the Laboratorio de Ecologia y Vida Silvestre (LEVS) and practiced bird monitoring techniques in different habitats throughout Chile, including work with the Critically Endangered Chilean Woodstar. At this same university, he continued with an MSc in Biology, where he explored the drivers of songbirds' clutch size variability. Throughout his career, he has been involved in the Chilean NGO "Red de Observadores de Aves y Vida Silvestre de Chile" (ROC), working actively in projects of seabird and waterbird monitoring and conservation, managing the Chilean eBird portal since 2015, being part of the editorial committee of the Chilean journal "La Chiricoca", and designing a network of shorebird protection. In this NGO, he also led the first Chilean Breeding Bird Atlas (the very first using eBird as the main data source, and the first in continental South America). Fernando also was part of the discovery of the first breeding colonies for Markham's Storm-Petrel, Ringed Storm-Petrel and Elliot's Storm-Petrel in the Atacama Desert. In 2019, he moved to Catalunya, where he has collaborated in tracking and sampling shearwaters, petrels, tropicbirds, and storm-petrels in Spain and Cabo Verde during his PhD with the Seabird Ecology Lab of the Universitat de Barcelona. Fernando is interested in finding novel approaches to studying the natural history of birds and has published several scientific and popular science articles (all of them available freely in Research Gate: https://www.researchgate.net/profile/Fernando_Medrano). He has also been at the forefront of bird conservation and has influenced light pollution regulation in Chile as well as the protection of colonies of storm-petrels in the Atacama Desert.

Ignacio Escobar Gutiérrez obtained his Bachelor of Arts with a mention in Musical Composition from the University of Chile. From an early age, he has been attracted to birds and nature. His interest in birds has been increasing and always with the interest of conserving them and compiling a wide catalog of their vocalizations. He has participated in several projects led by ROC: Neotropical Waterbird Census (CNAA) and Shorebird Census (MSP). He has also volunteered on projects to find new nesting sites for the Ringed Storm-Petrel and is currently volunteering to find nesting sites for the Wilson's Storm-Petrel. He is currently working to describe the acoustics of Chilean birds for Birds of the World.

Rodrigo Silva Caballero is a veterinarian, with an MS in Wildlife Conservation from the University of Chile. During the last 10 years, he has traveled widely in Chile, combining bird guiding, environmental assessment studies, and ornithological research. Currently, he works as Coordinator of the Seabird program at ROC (Red de Observadores Aves y Vida Silvestre de Chile, www.redobservadores.cl), leading several projects related to the natural history and conservation of desert-nesting storm-petrels and the Peruvian Tern. He is also part of the team involved in the search of storm-petrels breeding in the Andes.
