Abstract
Observations about negative interaction between Lontra felina Molina 1782 (Carnivora: Mustelidae) and Pelecanus thagus Molina, 1782 (Pelecaniformes: Pelecanidae) are explained in the present note. Field work was carried out in the small fishing town of Morro Sama, at the Department of Tacna in Peru. Four interaction events were documented during 2015, 2017 and 2019 which occurred in the surrounding of the dens of L. felina or in sites where fishermen discard fishing remains.
