I´m a brazilian biologist mainly interested on birds. I did my PhD in the Museu Paraense Emilio Goeldi, Belém, Brazil, on phylogeny of Megascops screech-owls, and have worked on birds censuses mainly in brazilian Amazonia for over 20 years - and also have some experience in Atlantic Forest, Cerrado and Caatinga. I worked as touristic guide in the Cristalino Lodge in Alta Floresta, Brazil, from 2018 to 2023. Now I´m startig a bird research project in the Carajás mountains in Pará state, Brazil.
