Gustavo is a Peruvian botanist that studied biology at the Pedro Ruiz Gallo National University in Lambayeque, on the north coast of Peru. He started working with The Macaw Society in 2005 as a field volunteer assistant and then came back in 2009 to be our field leader for five years. During this time, his main research was to document the phenology of plant species eaten by macaws and parrots in the area and estimate the food abundance in the forest for these species. In 2016, Gustavo worked on his master investigation focused on how environmental factors, such as precipitation, influence the phenology of the plants consumed by macaws in Tambopata. Currently, he is the Career Coordinator of the forestry and environmental engineering department at the Jaen National University in Peru.
