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. Currently I´m working as touristic guide in the Cristalino Lodge in Alta Floresta, Brazil.
